How to install the blade in the hand jigsaw

If in the quick-clamping mounts the saw is automatically fixed in the right position, then in the jig mounts you have to control it, which for many people is a tangible disadvantage, because it takes time. In addition, it is important to determine the correct degree of bolt tightening. If it is too tight, the blade will be very stressed and may break. And if it is weak, it will fall out or hang in the socket, and jigsaw work becomes impossible.

The second problem with these fasteners is the rubbing of the slits on the bolts with intensive work and frequent saw blade changes. Often there is also a breakage of the fastener or shoe thread, appearance of cracks on its body. It happens mostly with tools made in China from low-quality materials. A damaged sawblade cannot be repaired, it can only be replaced.

Classification of files

There are several kinds of saw blades that are designed for handheld jigsaws.

Name of saw blade	Short description
Standard or Standard tooth	The teeth are the same size and equally spaced apart. Can be used for most tasks.
Reverse or Reverse Skip-tooth	Some of the teeth on this blade are pointing upward. This allows the wood to be cut in reverse. That way there are almost no chips on the back side, making it easier to machine the wood.
Skipped tooth or Skip tooth blades	These saw blades are needed to reduce the risk of the hand jigsaw jamming and to avoid the high heat of the blade itself. Sawdust is also better removed, resulting in a smoother surface.
With double teeth or Double tooth blades	That way you get an almost perfectly smooth cut. The saw blade is almost heatless and removes sawdust well.

Also the blades differ in length. There is a gradation in numbers from 2.0 to 12. The bigger the number, the rougher the finish. That means you should buy large saw blades for work with thicker bars. If complicated patterns have to be made, it is worth buying small saw blades.

Depending on the type of work you plan to do, you need to buy this or that type of saw. They are strong enough, but with excessive tension can break, so it is always worth having a reserve for the possibility of completing the work, using a spare blade.

What a jigsaw holder can be

The jigsaw holder is the most vulnerable part in the machine in question. It is the one that is subjected to the greatest stress in the process of work, and accordingly fails.

The material for the file holder is usually of the highest quality, but not all manufacturers care about it, so the percentage of replacement of the node on jigsaws is high.

There are three types of holder, and each has its own features, how to install a jigsaw into an electric jigsaw.

Bolted clamp fastener (pad fastener)

This is the first option that began to be used on electric jigsaws. Almost all modern manufacturers have already abandoned the block fastening, as the replacement of the cutting part in this case. the process of laborious: unscrew the two bolts, put a saw, and then back to fasten them. You need to carry an Allen key for the operation.

Quick-clamping attachment

Used on many modern jigsaws. The process of changing the blade does not take more than a minute, as you only need to press the special button to loosen the clamp, and insert a new saw there.

Radial clamping

Easiest type of attachment. Used on newer jigsaws. For ease of operation, it is equipped with a spring that returns the jaws to their initial position.

Important! When replacing the cutting part, it is important to pay attention to the mounts, because they are the most common failures. Over time, a play appears there that causes the saw blade to wobble, affecting the evenness of the kerf.

Setting up in the jigsaw

The jigsaw is a comfortable fixture because both hands of the craftsman will remain free while working, allowing for more manipulation.

Warning! To use the machine it is desirable to use special blades with a pin. for reliable fastening. If you buy a sample without a pin, then the tightening must be made more carefully.

How the saw blade is properly clamped in the jigsaw jaws:

• Fix the blade in the special slots (first in the lower part and then in the upper part).
• The teeth should point down and away from the person behind the machine.
• The blade is tightened with a special lever.

If the jigsaw is tightened properly, it should jingle after a slight tap. If the blade does not have a font, it is necessary to fasten it very carefully, because it often pops out of the device.

How to work with an electric jigsaw: features and rules

Depending on the type of material, the rules of the cut are slightly different. And, to avoid mistakes, you need to familiarize yourself with how you should work with the jigsaw in a particular case.

How to cut metal

When cutting metal, a fine-toothed jigsaw should be used. For thin and soft material like copper or aluminum you may want to set the RPM higher. than 750 W is considered optimal. And, to reduce the friction force, you should periodically drip oil during work.

Important! When you cut sheet metal, it is better to put plywood under it to reduce vibration.

How to cut wood, chipboard, plywood

The biggest assortment of files is available for cutting these materials. But they must be used for their intended purpose. You should set the number of strokes according to the tool’s maximum values.

For the cut in this case you need saws with coarse teeth from 2 to 6 mm. The more difficult the type of work, the smaller their size. A straight cut can be made at high RPM, while a curved cut can be made at lower RPM.

After mastering the basic principles, how to work properly with an electric jigsaw on wood, plywood and chipboard to cope with such a task can not only an adult, but also a child.

How to cut metal tile

In this case, the greatest difficulty is the profile of metal. And in order to properly make the cut, it is recommended to clamp a sheet of material between the bars on both sides. This eliminates vibration and creates a certain gap for comfortable work.

Important! In order not to spoil the coating of metal during the cut, you need to wrap the sole of the tool with a cloth.

How to cut Plexiglas, plastic

To cut this material the same saws are suitable as for metal. Set the pendulum stroke to its minimum position or turn it off completely. Working with plastics, plexiglass should be done at minimum RPM.

How to cut ceramic, porcelain tile

When cutting these types of materials you should use saws with an abrasive edge. In this case the pendulum stroke should be turned off and the working process should be carried out at maximum speed. To cut ceramic and porcelain stoneware, you should rarely use a jigsaw, as these saws quickly deteriorate and need to be replaced.

How to saw laminate

When cutting this material, the only difficulty is that chipping occurs along the edge. To avoid this, it is necessary to use a saw blade with different teeth. And at the same time to make the cut not from the front side, but from the inside.

How to install the saw blade in the jigsaw machine

Considering the ways of installing the saw blade in the jigsaw, we could not ignore the most advanced type of this device. When working on a stationary jigsaw machine use thin blades with pins on the ends, similar to those used in hand tools. Some models have adapters to work with saws without pins, but this function is considered quite rare. If you have recently become the owner of such a machine and do not yet know how to insert the blade in a jigsaw of this type, just read the following text.

An undeniable advantage of pin saws, is the simplicity of their installation, which does not require unscrewing and tightening clamps. In any jigsaw machine there are special grooves where the ends of the blade are placed and fixed. First of all, the saw blade is installed in the lower element of the fixture, then in the upper one. Teeth of installed blade must face downwards and be directed to the operator. After making sure that the cutting side is correctly positioned, it remains to tighten with a special lever located on the opposite side of the device, on top. To check the tension, lightly flick the saw with your fingernail, like a guitar string. A high sound will mean that the blade is ready to work.

Saw blades installation without pins, in each device is realized differently, but absolutely everywhere occurs through adapters. The first thing to do is to tighten the blade tails in the adapter, then fix the assembled construction in the machine’s fasteners. To see more clearly how to insert the saw into the jigsaw correctly, with the following video.

Device and characteristics

It should be noted initially that the tool is divided into two large classes: manual and electric jigsaws.

The former are more suitable for fine and precise work with small elements, while the latter are mostly used for quick shape holes or straight cuts.

The design of a hand jigsaw is very simple, it consists of the following elements:

Arc-shaped metal frame of small size.

Predominantly made in the shape of “U” or “C” in steel.

Its main peculiarity is the big gap between the upper part and the stretched cloth.

This allows the frame to avoid resting on and around the edges of the workpiece.

If it is required to make a cut along the mowing line, which must not extend beyond the billet, a hole is drilled in it.

Then the webbing is removed from the frame, and passed through this hole, and reattached to the frame.

The blade. the working, sawing part of the tool with fine teeth.

Stretched between the ends of the frame (fixed by its fasteners).

Has one major disadvantage. low mechanical strength, which, coupled with the small size of the frame makes it impossible to saw at a large distance from the edges of the workpiece.

The blade itself often just breaks and breaks off.

Handle, an element for holding the tool comfortably with one hand, mounted on one side of the frame.

Made of wood, metal or plastic.

The standard electric jigsaw consists of:

• Casing with a practical handle and start button in which all the electrical elements are hidden.
• Motor with gear box.
• Stem.
• Saws.
• Guiding reference plane fixed in the lower part of the housing.
• Various optional extras for user convenience: backlight, pendulum motion switch, additional guide mechanism, laser pointer, etc.

The principle of an electric jigsaw is the reciprocating movement of the saw at high speed.

It is fixed in a rod that is moved by power transmission from the motor through a gearbox.

Cutting is perpendicular to the work surface.

Sizes and weight

The most common manual jigsaws have a weight of 285 g with a blade length of 130 mm and a cutting depth of up to 300 mm.

But the tool can also be found with the following parameters:

Parameters of typical electric jigsaws:

Basic types of Japanese saws:

DOZUKI. saw with a thin blade reinforced with a special shank. For very fine and precise cuts with a very clean cut surface KATABA. saw with a blade without shank. Designed for long, deep cuts. Often used with a jigsaw

RYOBA toothed saw with teeth on both sides of the blade. As a rule, the teeth on one side are trapezoidal, for cross-cutting, the teeth on the second side are triangular, for longitudinal sawing

Mawashibiki. canting saw with a narrow, soft curved blade. For sawing curved cuts in wood, wood panels, drywall etc.п.

Kugihiki. saw with super flexible blade. Designed for cutting plugs that protrude from the workpiece surface. Tooth setting on one side.

Deluxe saws. All saws with this mark are handmade by Japanese craftsmen. They are always specified as a geometric average. Almost all well-known Japanese carpenters and joiners use only custom-made saw blades. Deluxe saw blades have tighter tolerances and are often less thick than the factory-made products, usually with a blade thickness of less than 0.3mm. The blades are treated with a special scraper to give them a cone shape: Ryoba blades are thickened towards the center of the blade, while Dozuki and Kataba blades are thickened towards the back. The sawblades are hand-hardened and are thinner, so they wear out quicker than ordinary saw blades that can be sharpened with an emery board.

Leader among Japanese saws. Silky Blade Saws They are characterized by the highest quality of workmanship, have an extremely efficient cut, great durability and a chrome coating of the blade that significantly reduces the friction force while sawing. Great ergonomics and design of these saws.

DICTUM. saws (both Japanese and European) of the united company Dictum are very popular in the world and in Russia. They are inexpensive, but time-tested and have no owner complaints. The history of DICTUM begins in Saxony, Germany, when Johann Friedrich Dick founded a company for the production of musical instruments in 1848. In the early 1980’s, under the impression of Japanese carpentry tools, the DICK brothers developed and started to produce woodworking tools under the Dick brand.Since 2011 the company has been transformed into DICTUM, combining the two brands Dick and HERDIM.

Tool Tip Basics: Jigsaw : Tool Tip Basics

Different tooling types by cutting edge geometry

Teeth on different types of tools have different setting values and geometry of cutting edge. How the teeth of the jigsaw are tilted determines the speed and quality of the thread.

Milled with the classic approach

In this case the teeth have to tilt like regular hand tools. Cutting speed is high, but it is impossible to make a accurate cut.

Milled with corrugated

With this jigsaw jigs, the teeth on the blade change direction in groups. Each tooth is offset at an angle from the central axis that is different from the adjacent teeth and therefore creates a wave.

Sanded with the classic set

With this design, the teeth alternate on their sides. In this manufacturing process, they must be ground. This accessory allows you to work much faster and get a fairly clean cut.

Conical-grind without counterbore

On these blades, the teeth are not offset from the central axis but are ground. This permits a fine cut and a precise sawing operation.

Important! For accurate work with no chips when sawing laminate surfaces it is recommended to use a special saw blade with two rows of teeth.
