Can I cut metal with a coping saw?
Circular saw. how to choose a decent tool?
After you paint the tiles, you need to protect the paint, so it always looks like new. This is especially important if you painted clay tiles on the floor. Give the newest paint two or three days to dry. Then apply two coats of varnish on an aqua base. It will hold up very well to the freshest paint. I do not recommend using an oil-based varnish, t.к. Over time, it tends to yellow a little (although you can use this yellow patina for design purposes), but aqua-based lacquer always stays clear and transparent. Generally speaking, varnishing. This is an integral part of a project like painting clay tiles. Lacquer. a very sturdy thing, and it does a terrific job of protecting the paint from such threats as “foot traffic”, the invariable movement of glasses, plates, pots, pans, etc.д. on your kitchen countertops. Everyone knows how well varnish protects wood surfaces from wear and tear. The same can be said about painted surfaces. This is especially true for painted clay tiles on the floor. Lacquer coating will protect the paint and give you long and lasting years of beauty. As proof of this I can give you an example. Think of the gym at your own school or your children’s school. There’s also a painted floor. And it withstands superintensive use, requiring only little maintenance.
- Creation of such a saw with their own hands will save money. For example, to finalize the grinder spent approximately 500. Price is suitable for most masters.
- The main features are chosen to suit your needs.
- By making the tool yourself, the craftsman will easily find the causes of problems and eliminate them.
- Factory-made products have a stock of durability and a guarantee, and self-made structures are usually made of some unnecessary things.
- Trimmers of their own making are rarely powerful enough, as high-quality spare parts are needed for the best of their work.
- Sometimes the money saved on the purchase of factory units is spent on rework, repairing homemade.
- Professionals often put their lives in danger because, saving money, they do not equip the device with safety features.
- Factory options have a scale that shows the angle of the wood cut in detail. It is difficult to make such a device on your own device.

Homemade mitre saws have both positive and negative features.
The advantages of homemade units include a number of characteristics.
- To create a crosscutting machine you will need to invest an order of magnitude less money than to purchase industrial equipment for crosscutting wood, pipes, plastic, etc. Approximately the specialists to re-equip angloshlifovalyh machine into slicer put from 500 to 1000.
- You have the opportunity to select the performance characteristics for the future end mill by yourself. These parameters include the size of the working surface, the power of the electric motor, disk diameter, kerf depth, etc.
- Manufactured devices have an uncomplicated design. For the reason that you yourself collected and disassembled the device, there will be no difficulties with the search for damage.
There are also disadvantages, among which are highlighted several factors.
- Homemade units usually use old, useless materials, tools and appliances. This adversely affects the quality and durability.
- They are often not very powerful.
- In some situations, saving on the purchase of an industrial model becomes farfetched, because a lot of money is spent on repair work, re-equipment, preventive measures of a self-made unit.
- You put yourself at risk, in terms of your own safety, by using a homemade crosscut saw.
Having an angular grinding machine, a manual circular saw for wood and metal, you are free to make a home machine. Follow the instructions, follow the safety rules.
Be sure to take into account the presence of protective guards, as work on such machines is not entirely safe.
How to saw laminate with a circular saw
Not everyone is likely to buy such a tool, but those who have it will enjoy working with it.
The power of the device for sawing is much higher than other power tools. Therefore, if choosing what is the best way to saw a durable and hard commercial grade laminate, it is worth choosing a circular saw.
Sequence of operations when working with a circular saw to cut laminate boards:
- disc for the circular device choose with small teeth;
- On the decorative surface of the board, make a marking for trimming;
- the boards are placed upside down with the decorative layer one by one on the machine, holding the panel by the edge, slowly guide it forward toward the rotating disc.

I read somewhere that there is no way. And it turns out you can” I wonder what diameter he used.
I think 200×32 mm through the adapter washer. You can in our country all you can)))
In a TV show I saw, as the men cut steel profile circular, but not such a pendulum, and which moves on the rod. They had a metal disc there, and I think they even poured coolant.
Yeah. I guess our people have a lot of health.

There are disks for steel and stainless steel (metal). Only the power of the saw should be enough. ” here is an example, there are videos. how people saw channels and even gas and oil pipes with a hand saw.
Actually, there are special saws that look very similar. Unknowingly, it’s easy to get confused. Metal cut-off saw 2414NB (abrasive disc) ” Metal cut-off saw LC1230 (carbide disc) ” Metal cut-off saw LS 1040 “

they are universal. they cut both metal and wood, the one that purely on wood cannot cut metal because of design differences, “wedge”, for example. There are also cantilever and pure metal trimmers with low speed and coolant supply. Only because of the lack of availability on the market and people put cutting discs on trimmers, although the money will be cheaper to take the same Jet ribbon.

Stock of what? ? To be clear, I suggest we measure linear velocity for abrasive. 75-80 m/s for hard metal. no more than 35 m/s if the drive is good. The Makita mitre cutter you quoted above has a linear speed of 61 m/s with a 255drive. If you put a 255 carbide in there that’s a lot, the drive will fly away. If you somehow stick 230 abrasive angle grinder there, the linear will be 55 it’s not enough for the abrasive.

There are no purely metal trimmers. you have a metal cut-off saw (or better yet, a circular saw).

There is everything or much on the market in almost every corner of the vast. I’m afraid it’s more often greed and Olympic feelings. for many people it is NOT SPORTS to buy ready-made tools sharpened for specific purposes, everyone wants universality.
Can I use a coping saw to cut metal?
Metal cutting can be done either hot or cold. The hot method is based on heating the cutting point to its melting point. These are methods such as laser cutting, electrode cutting, gas cutting (plasma cutting), autogenous cutting.
These types of cutting are used in most cases in production.
Cold cuts include guillotine cuts, bevel cuts, angle grinders, hand held tools like scissors, a metal saw, drill bit. The most progressive and convenient is considered a metal cutting mitre saw, which is designed specifically to work with metal.
Usually the crosscut saw having a usual set and an average power motor is used for cutting work on wood, but there are crosscut saws on metal and wood which can cut metal, but mostly color and plastic, and, of course, wooden workpieces if the right saw blades on metal for crosscut saw are used.
Which device to choose. a sliding compound mitre saw or a circular saw for metal
The principle of band saws is that the cutting tool is not the disk, but the band blade and a special gear on it. Working speed is slow enough, about 100 revolutions per minute, but this tool can saw large enough diameters, both logs and metal pipes.
Diagram of a band saw for metal cutting
Like any tool, band saws come in a variety of forms:
- Household, when the feeding of the frame, in which the saw blade is fixed, is done manually. It is used for sporadic work when sawing soft grades of steel. Technology does not use coolant in these machines.
- Semi-professional saws, where the frame is lowered using hydraulic feed. In this equipment it is obligatory to use coolant. Hard grades of steel can be sawn with these machines.
- Professional band saws are fully automatic equipment, where the work is done by the operator. Good work speed, cutting quality, usually has swiveling jaws that allow you to make sawing at an angle of 45 degrees.
Professional band saws for metal cutting
A big plus of the saws is the band saw blade itself, which can be installed on any machine manufacturer and capacity.
The Jet J-349V semi-professional saw has very good reviews, priced from 36000.
A good option.this is a semi-professional band saw from JET company
Can work with workpieces from 125 x125 mm its weight is 19 kg.
When choosing a pendulum saw, you need to consider its principle of operation: performance, accuracy of work and the ability to cut at any set angle. The principle of the pendulum is that the cutting mechanism itself works on the same principle as a pendulum: up. down. Its main part is a circular saw.
Metal cut-off saw has advantages over other tools in that it:
- The tool has many functions;
- with the help of the pendulum node, the cut itself is obtained with high precision;
- the working speed is quite high;
- It is very easy to buy a pendulum metal mitre saw, as well as set it up for work;
- easy maintenance and change of saw blade.
One significant disadvantage of this saw is its high price, especially if it is a professional tool. It is a professional tool for metal.
There are also inexpensive trimmers from Russian manufacturers, such as Elektropribor software company.2400 Dm which can work with metal,
An excellent option for dry cutting of ferrous metals is slicer Russian-Taiwanese manufacturer Messer DRC 355 at a price of 43000. The reviews are all excellent, the design is well made and the workmanship is value for money.

You can buy a crosscut saw for metal in Leroy Merlin. They are much cheaper than other stores, such as Metabo CS 23 with a 355 mm blade costs 10980, Corvette 431 for 7800.
Can torzovoy saw cut ferrous metal
There is a lot of controversy among professionals about cross-cutting saws for cutting metal. Those crosscut saws, which have an angular speed up to 5000 rpm and power up to 1, 8 kW, even when using carbide discs for cutting metal for crosscut saws, can cut thin sheet, non-ferrous metal, plastic, but ferrous metals are not suitable for them.
If you take the pipe or other rolling, for this there are special cutoff machines, which are almost the same as trimming saws, but have other technical specifications. This is a serious tool that will not buy the amateur, what would once a month to cut a piece of angle. So, for example, the linear speed should be at least 1, 5 times less, the power of 2 kW, the drive larger, the average size of 350 mm.
If you buy a reciprocating saw for metal, her, she cuts and thin-walled pipes and rolled metal with 3.5. 4 mm wall. At the same time, users note that for thick workpieces they just have to change the saw blades for metal facing saws more often, which is not a cheap pleasure to buy.
Here is such a serious tool. cut-off saw Makita LC 1230
Diameter of the blade is 305 mm, it is direct driven, with a motor power of 1750 W, maximum rpm is 1300 per minute.
Not bad reviews also about the Makita 4131 pendulum cut-off saw, which can cut metal up to 5 mm thick. The tool has many additional useful options. It is a protection against overheating of the motor, and the shaft lock, and the ability to adjust the depth of cut itself and locking button from accidental activation. The assembly has excellent insulation.
So the answer to the question whether it is possible to saw metal with a crosscut saw will be: of course it is, but not every saw and not every disc. To buy a good and working metal disc for a crosscut saw, you need to remember that it should be a carbide disc with a high number of teeth, more than 60. It should be made of steel with increased m carbon and alloyed with molybdenum, nickel and chromium for greater hardness and durability.
All about mitre saw blades
Such a tool as a crosscut saw is not familiar to everyone. Despite the large number of materials this tool can cut, its main purpose is specific. That’s why this saw is most often used by professional finishers. It does not become necessary at home very often. However, when you do not want to overpay for repairs, it makes sense to buy all the necessary tools to facilitate the work.
But in this case it is necessary not only to understand the principles of work with it, but also to understand the consumable parts of this tool. The main of such parts is a cutting disc.
Pros and cons of carbide discs for metal
It should be noted at once that there are many advantages over abrasive discs, but the price of equipment and discs themselves restrains the popularity of their use. Let’s talk about everything one by one!
- Cutting precision. In order to maintain accuracy when cutting metal workpieces, a carbide blade on a pendulum saw is one of the best options for the job.
- Speed of operation. You will be surprised how fast the carbide blade saws.
- Great disc life. The average life of a disk is five thousand cuts. Compared to abrasive, it is immortal.
- No harmful emissions. When working with an abrasive, a cloud of fine particles is formed in the work area, which negatively affects human health.
- Metal does not heat up. After you cut the workpiece, you can safely take it, it will be cold. The main advantage is that it does not change the properties of the metal without being exposed to temperatures.
- Price. Cost of carbide disc is ten times higher than abrasive disc. Metal cutting assembly saw with Makita lc1230 carbide-tipped (pobedite) disc (305 mm). At home, with infrequent use, such a disk will not pay for itself.
- Metal loss. Since discthicker than the abrasive, then it is worth considering that the line for the trimmer cut will be thick.
- Fear of rust. If you think about sawing metal with rust, remember that it will wear out the disk faster.
Making a conclusion about all of the above, we can say that the carbide discs belong to the more professional consumables. They have fewer disadvantages than competitors, but the price makes them unaffordable for domestic use.
The design of the mitre saw is quite simple: its main elements are the gearbox, the cutting disc, the base, the handle with the start button, and the motor. Today it can be manifold and asynchronous. The first variant is good because it is easy to maintain, the second one is durable and makes less noise during work. Regarding the type of transmission, it can be belt or toothed. Exactly the first one is almost silent, in this case the disk does not vibrate.
The disadvantage of this type is slipping off the base if the machine works for a long time. Toothed variant does not have this disadvantage, but such a saw is noisy and vibrates when working. The disc, which is the key element of the saw, is made of durable metal, because it must withstand an enormous load.
To make the unit produced less noise, as well as to compensate for the deformation that occurs at high temperature, the planes of toothed saws have waves or cuts.
Another feature of crosscut saws is the pivoting table. Precisely because of this type of platform and is performed cutting at an angle. For maximum precision, the saw is equipped with a finely graded scale. The scale is convenient in that the operator does not need to make additional measurements with auxiliary devices. Some models are even equipped with a laser ruler.
In addition, the product can have automatic broaching. This is convenient because there is no need to independently move the metal to the desired point: special grippers will do it. Also modifications can be equipped with special dusters, thanks to which one can forget about disposal of chips and waste. This equipment is relevant to the maintenance of the workplace.
Knowledge of the basic characteristics of crosscut saws for metal will allow you to buy the right option, based on the type of tasks and their own preferences. When choosing between the electric drive types, preference should be given to those in which the electric motor is located behind the disc. unlike left or right handed counterparts, this model has an unobstructed view and is less likely to cause injury.
When choosing between the types of transmission, it is necessary to weigh the pros and cons. For example, products with belt drive are low-noise. But if oil gets on the belt or pulley, it will cause an accident. When accelerating, the belt can slip, which is a recondition for repairs.
As for the toothed transmission, there is no slip, but noticeable vibrations will quickly wear out the cutting elements of the device. When selecting the optimum power, you should look for products not lower than 1500 W: they are the ones capable of cutting thick metal. The maximum bar is 3000 watts. Analogues with a power of 1000 watts cope with thin workpieces.
The label of the wheel indicates the expiration date, the number of revolutions, the material marking, which is coded by letters and numbers. After the expiration date, the nozzles become brittle and the abrasive crumbles. The date until which the disc can be used is indicated on the label, next to the seating hole.
Pay attention to the RPM limits when purchasing. It should be equal or less than that of the tool
The abrasive discs for angle grinders necessarily have the abrasive material marking in coded form. The material coding can be broken down as follows:
- The material from which the abrasive grit is made is indicated by a Latin letter (or two letters). For example, a wheel marked with the letter A has an abrasive consisting of electrocorundum. White corundum (AS) does not cut stainless steel; silicon carbide (S) is not suitable for metals at all.
- The grit size of the abrasive material is indicated by the number following the letter designation of the type of abrasive particles. The higher the value, the smaller the particle size. To work with ferrous metals, you need discs with coarse grit (up to 30), for non-ferrous metals suitable fine grit (from 40).
- Abrasive bond hardness is indicated after grit size. It is indicated by a Latin letter. The further the letter is from the beginning of the alphabet, the harder the bond. The softest bond is A, the hardest is Z. Brushes with soft grit are used for hard metals. A hard bond overheats the machined surface, cuts with difficulty. Soft bond wears out quickly.
- Bond materials are identified by one or two Latin letters at the end of the coding.
For example, a blade marked A24R BF has a corundum, coarse-grained, soft, bakelite bond.

Disc diameter as a function of the machine’s speed
The dimensions of wood saw blades are as follows.
- disc diameter up to 80 mm applies at 23 800 rpm./min;
- up to 100 mm. at 19 100 rpm./min;
- up to 120 mm. at 15 900 rpm./min;
- 250 mm. at 7 600 rpm./min;
- 300 mm saw blade diameter is used at 6 300 rpm./min.
Remember that the larger the diameter of the blade, the lower will be the rotational speed of the saw. This is an important factor to consider when selecting equipment.
Cutting pipe with a pipe end saw with a metal blade. is it possible??
ImhoDom Forums hands out of the shoulders Cutting pipe profile cutoff saw with a disc for metal. you can? There are 9 replies in this thread, 7 participants, last updated by kaifsheg 5 years/years, 11 months. back.
Greetings. I don’t have a pendulum saw and/or a band saw on hand, t. ч. the question arose, but need to make a cut on a profile tube (ferrous metal, 50h50h2).
Accordingly, the question. is it realistic to use a crosscut saw with a disc for metal (cut-off) and, if so, what should be the RPM/power?
Is it realistic to use a jigsaw with metal saws and, accordingly, what should be the power?
1.Buying a band saw/pendulum saw doesn’t fit into this design budget, cutting to order, again, excluded. too troublesome with shipping, etc.
The problem with the angle grinder is to get more or less close to 90gr. cut, that’s why I want to use a mitre saw (which has a 90gr. set) or the jigsaw on the guide rail.
Budget, here’s a pendulum for a simple angle grinder.
On a facing machine, you can put a disc for metal, but the angle grinder. disk on wood can not, different speed, it can all end badly.
It might come in handy, I haven’t used abrasive discs like Luga for a long time All cut with diamond “turbo” on a stone, one disc lasts for a year or two. The price of 300-500r pays for itself once in 10-20 times.
There are metal cut-off machines. The price of Interskolovski and other Chinese about 2.5 thousand. They are just for abrasive disks. Slicer I would not spoil. There’s a lot of plastic on it, and as you know it burns from sparks. And yet for facing discs have a metal discs with a carbideide tips (disk with teeth, but another form compared to the wood). It costs about 6 thousand.
Something you, my dear, you are too high 6 thousand for the drive. At these it’s easier to buy an angle grinder, complete with a pendulum.
Jigsaw. definitely not considered, nonsense, sawing pipes with a jigsaw.
Trimmer with a cutting disc. the saw will not live long, the disc will not fit, it is necessary to cut an adapter, and the speed with the power is not the same is also not an option
The stand for the angle grinder. flimsy, uncomfortable, the corners float, it is desirable to mount it stationary, otherwise the angle grinder can behave unpredictably. If you need to cut a little, you can get by with this diamond. the lesser of two evils. But if you need to saw in the future, I strongly advise you to buy a cut-off machine. 6-8 thousand, but it’s worth it.
It might come in handy for someone, I haven’t used abrasive disks like Luga in a long time We all cut with a diamond “turbo” on a stone
And what kind of? I tried several. they get very hot. I’ve tried solid, for waterless cutting.
My Matrix went a year, everyday use, until the car was not opened, and the angle grinder did not do a foot saws certainly slower than the abrasive, but the roof beats itself for 2-3 days and tiles, and sawed pipes and rebar.
And it’s really bent. Apparently, I was deceived by the salesman in the store.
I saw a corner with a 5 mm shelf was sawed with such a disc. thickness. Saws!
as commonly understood with crosscut saws you can cut wood, plastic and soft metals (alumina, plastics, etc.). profile). such saws, as a rule, have the power of 1,3-1,8 kW, disk up to 200-300 mm, speed 4000-5000 rpm.
pipes and other metal is sawed with cut-off saws. They look about the same as the facing tools, but have different characteristics. power from 2,2 kW, disk from 350 mm, speed up to 4000 rpm.
at seemingly small differences in the characteristics, the linear speed of the circular saw blade will be about 1.5 times less than that of a cut-off saw, with more power of the latter. so the crosscut saw simply can’t take the load when cutting metal.
we mustn’t forget about problems connected with compatibility of tools and disks (thicknesses, diameters, seating dimensions).

How to choose a crosscut saw blade for metal
This tool appeared on the market relatively recently. Metal disc for mitre saw? Many people, even experienced craftsmen, find this source of derision and disbelief. Not so long ago, steel was only amenable to gas flame cutting, angle grinder’s circle and metal hacksaw. Only wood and plastic materials could be cut on mitre saws.
But time is of the essence. Material engineers in tandem with toolmakers are constantly working on synthesizing new alloys. Today, metal cutting discs for mitre saws are available at any tool store. But this tool works under tough conditions and is subject to wear and tear.
Metal mitre saw
Metal cutting can be done by either the hot or cold method. The hot method is based on heating the separation site to its melting point. Cutting methods such as laser cutting, electrode cutting, gas cutting (plasma cutting), autogenous cutting.
These types of cutting are used in most cases in production.
Cutting by cold method include those such as guillotine metal cutting, cutting with an angle grinder, cutting with a hand tool, such as scissors, a hacksaw for metal, an attachment to a drill. The most progressive and convenient is considered to be a metal cutting mitre saw, which is designed specifically for working with metal.
Usually a crosscut saw having a usual set and an average power motor is used for cutting wood, but there are metal and wood crosscut saws, which, provided the right saw blade for crosscut saw is used, can cut metal, but mostly color and plastic, and, of course, wooden workpieces.

Those crosscut saws, which have an angular speed of up to 5000 rpm and power up to 1, 8 kW, even with the use of carbide discs for cutting metal for crosscut saws, can cut thin sheet, base metal, plastic, but ferrous metals are not suitable for them.
If you take the pipe or other rolled products, there are special cutting machines for this purpose, which are almost the same as trimming saws, but have other technical characteristics. This is a serious tool, which will not be bought by a hobbyist, just once a month to cut a piece of angle. For example, the linear speed should be at least 1.5 times less, the power of 2 kW, the drive more, the average size of 350 mm.
