How To Make A Hole In Metal Without A Drill

How to properly drill a reinforced concrete pipe with an impact drill

When using a percussion drill for reinforced concrete, you need to use the “hammer drill” mode and winder drills. At first, the hole is made with a smaller volume, then a larger one. The drill needs to be cooled periodically.

Important! When working with concrete, you must not get into the reinforcement, otherwise the drill will break. Using a special device, you can check where it is located.

There are such crowns for drills. But they have a coating of a different nature. from a cabrid-tungsten alloy. It is convenient to use them, since it is quite within her power to drill a hole in the concrete wall with a drill and at the same time make a hole in the tile. Such crowns are used only with powerful drills.

Borax is another tool than drilling a concrete wall. Their diameter is varied. In the overwhelming majority of cases, when installing hidden electrical wiring, you can not do without such a dirty and noisy procedure as shtroblie. Experienced craftsmen advise to make a selection based on the diameter of the dowels.

How to drill holes in a brick wall: the choice of tools and attachments

To make a hole in a brick wall, a punch with a drill or an impact drill is suitable, most often the latter is used. Its power must be at least 600 watts, the minimum number of revolutions is from 2500 per minute. It is best to use a drill with stepless power adjustment and quick clamping function.

By using the hammer drilling function, the drill becomes identical to the hammer drill. The speed and ease of operation are increased. To make a hole in a brick wall, you need to use the dynamic blow method. Without this, the drill will not be able to catch on the inside of the brick.

How to drill a concrete wall. a possible way out of the situation

Sooner or later, most people living in houses with concrete walls need to hang a cabinet, lamp, shelf or painting. At this point, the pressing question arises of how to drill a concrete wall. It is no secret that every home craftsman has encountered this problem at least once in his life, but not everyone knows how to solve it. Many courageously torture the drill and their own strength, but without achieving the desired result, they abandon everything until the next attempt to make a hole in the wall. But the drill eventually breaks, and the shelves remain standing somewhere in the corner of the room or gathering dust in the closet. But there are still options. you just need to know and be able to use them.

Which attachments to choose

A specific nozzle is used for each material:

  • concrete, brick, stone. a drill with a carbide plate or a victorious one;
  • tile, glass. conical drills with diamond dusting;
  • metal. spiral drill with a cylindrical cone;
  • wood, drywall. for holes of different diameters, drills are used: feather, ballerina, screw, saw crowns for wood;
  • foam concrete. victorious drills.

How to fix a large drilled wall

You can fill in unnecessary holes in the wall using a special building mixture. It provides strength and durability. The composition must be selected depending on the area and type of defect.

With the help of putty, you can level the surface, including concrete. There are several types of putty:

  • cement. used in exterior and interior decoration, suitable for concrete. Durable and moisture resistant. It dries for a long time and often with a mesh, which requires reapplication;
  • gypsum. used in dry rooms, is not resistant to water and is afraid of temperature extremes. Does not crack when applied, therefore, it can be applied immediately in a thick layer;
  • acrylic. finishing. It should be applied in a thin layer, therefore it is suitable for small imperfections.

None of the mixtures are used to seal through holes.

Polyurethane foam is a versatile material. There is one-component (used without preparation) and two-component (when using a construction gun or mixer).

When applied, the foam increases in volume and fills the required space. Freezes and gives a high-quality density. Deep holes can be closed.

The repair mixture is suitable for removing large defects. Has good adhesion, frost-resistant, strong and durable.

When deciding to make a hole, carefully read the rules and recommendations. Choose a tool, depending on the composition of the surface, and the drill. If you are not sure of your own skills, then entrust the work to specialists.

Tools for work

Different tools are used for work, the main ones: a drill, a perforator, a screwdriver. There are nuances when using each.

Hole in metal without drill

To drill through thin metal or plastic, you need a screwdriver and a self-tapping screw with a cutting head. It comes in different lengths, it is better to take a short one.

  • Mark the point on the surface where you will drill.
  • Insert the self-tapping screw into the screwdriver and carefully screw it through
  • At the same time, press it down so that the point cuts into the workpiece and pierces it.

The operation will only take a few minutes and the passage is ready. With this self-tapping screw, you can cut several openings, then you need to replace it.

Also these tools are suitable for drilling holes in wood. First you need to screw in a small self-tapping screw, and then a larger diameter.

Hole in glass without drill

A way to make a hole without a drill in the glass so that it doesn’t crack. This will require molten lead.

  • Load lead fishing weights into metal containers.
  • Light the burner and melt them.
  • Wipe the glass surface with rubbing alcohol to remove grease and other contaminants. Otherwise, the glass may crack.
  • Pour fine wet sand into the cleaned area.
  • Using a stick, make a semblance of a well to form a vessel.
  • Pour molten lead into this vessel. Thanks to wet sand, the temperature inside the well will be kept for a long time.
  • Clean the surface after 1-2 minutes.

In the place where the molten lead was poured, a hole is formed. And the glass will not be damaged.

Hole in brick without drill

The way out is how to drill a hole in the brick if there is no drill. The main thing is to find a drill for metal of the required diameter at home.

  • Break off the spiral rod strictly perpendicular.
  • Use this drill and hammer to punch a hole in the wall.
  • Rotate it clockwise regularly. Then it will gradually deepen more and more.

It will take about 5 minutes to make a 5 cm deep hole with a broken drill and hammer. Therefore, if necessary, you can punch brick with these tools.

Hole in plastic without drill

A simple way to make an opening in plastic. To do this, you can use a conventional gas burner and an awl.

Heat the awl red-hot with a torch and carefully pierce the plastic. You will get an even hole in the plastic, which is quickly made without a drill.

Instead of an awl, you can use a nail clamped in pliers. And the burner can be replaced by a switched on gas stove.

Of course, if there are many holes to be drilled, then a drill is best. But 2-3 punctures can be easily done this way.

How to make a hole without a drill: 5 ways to drill materials

We will tell you what to do if you need to make a hole, but there is no drill or screwdriver. You will learn 5 ways to drill wood, metal, brick, plastic and glass without drilling tools.

How to drill a long hole in wood

Sometimes it becomes necessary to make a through opening in a long wooden block along its entire length. For example, to drive in a hairpin or wire. Even with equipment or long drills, this is difficult to accomplish. The drill will definitely go unevenly and will not get from one given point to another.

But there is an easy way to make a clear and even hole without using a drill, drilling or lathe. To do this, you need a circular saw and a router with a limit ruler.

  • Mark the place where the hole should go.
  • On the circular saw, align the saw blade with the markings and unfold the block.

  • Move the router to the marked risks of one workpiece, and mill the groove. Do the same with the second part.
  • Now restore the integrity of the bar, glue both blanks.
  • The hole is ready. A cable or hairpin will fit perfectly into it. If necessary, fix them, mill a shallower depth before compression.

    Equipment types

    Drilling begins with preparing the tools for the job. You can make holes using a screwdriver, drill or special drilling machine.

    make, hole, metal, drill

    To make a hole, you need to select the appropriate equipment. For metal blanks, you need to choose specialized tooling that is suitable for this particular material. This is due to the fact that equipment for wood, concrete or ceramic tiles has a different sharpening and shape. Tooling for metal products is marked with the letters HSS.

    The working part of the tool is coated with a titanium nitride coating, which increases their strength and wear resistance. For hard steels, a different tooling is used which is designated P18. The strength of the instrument is increased when cobalt is added to its composition. Example of marking. Р6М5К5.

    To drill alloy steel, drills with a carbide tip are used. With their help, you can drill any metal workpiece, however, due to the high price, this is not cost-effective.

    Once the hole has been made, you can match the drill bit to the thread. Its diameter will depend on the previously used rig. Tapered drills can be used to make holes of different diameters in thin metal sheets.

    How to properly drill metal?

    When you turn on the tool, the drill may slide to the side, which prevents you from making a hole in the selected place. You can cope with this problem using a core sample. It is a metal cylinder with a sharp end at one end. It is necessary to attach a sharp end to the marking and hit the back of the core with a hammer. A notch will remain on the metal, along which a hole is drilled.

    Application of lubricants

    When drilling holes in hardened metal, it is imperative to use a lubricant. It partially cools the working area, preventing the equipment from quickly failing. Regular machine oil or special drilling mastics can be used as lubricants. Correct lubrication is as follows:

    Milling Without A Mill! (On The Drill Press) | Güth Blades

    • The drilling area on the hardened metal is marked with a core. A small amount of grease is applied to this point. If it is liquid, then squeeze out a drop of oil so that it does not spread.
    • The cutting area of ​​the tool is dipped in lubricant and set at the previously marked point.
    • During drilling in hot metal, the amount of lubricant is monitored and added as it develops.
    • They monitor the state of heating of the tool, preventing it from overheating. Intense smoke emission from burning grease indicates the need to stop work and cool the tool and metal.

    Deep hole drilling features

    Holes are considered deep if they are larger than five drill diameters. The peculiarity of the work here lies in the difficulties associated with cooling and chip removal. The cutting length of the tool must be greater than the depth of the hole. Otherwise, the body of the part will overlap the helical grooves, along which the chips are removed, and also the liquid for cooling and lubrication enters.

    First, the hole is drilled with a short, hard drill bit to a shallow depth. This operation is necessary to define the direction and centering of the main tool. After that, a hole of the required length is made. As you progress, you need to remove the metal shavings from time to time. For this purpose, use coolant, hooks, magnets or turn the part over.

    How to drill hardened steel at home

    To improve the basic characteristics of the metal, it is often hardened. This technology provides for an increase in the hardness of the product due to strong heating of the metal and its rapid cooling. In some cases, drilling has to be performed after heat treatment. By increasing this characteristic, it becomes more difficult to drill hardened metal. Let’s consider all the features of drilling hardened steel in more detail.

    Drilling methods for hardened steel

    Drilling in hardened steel is characterized by high heating of the surface of the workpiece and tool, which leads to rapid wear of the latter. Therefore, during processing, they try to remove excess heat or make it so that the area where the channel will be becomes softer.

    How to make hole in heavy steel bar or metal

    The first method, which makes the hardened metal more malleable, is based on the use of acids. Suitable substances include nitric, perchloric or sulfuric acid. These liquids are applied pointwise, that is, they are used to treat exactly the place where the hole will be in the future (the area is etched). To prevent the acid from leaving the working area from materials that are not exposed to acid (polymers, paints, paraffin), something like a side is organized around the future hole. The hole is filled with active liquid and kept for a certain time. Next, drill with an ordinary drill.

    Another method of weakening the hardness of the hardened metal in the channel receiving zone is based on heating this zone to high temperatures. The welding machine copes with this in the best way. In this case, it is necessary to correctly select the arc force so that the metal does not melt or deform. When the workpiece in the drilling area is hot, you can make a hole with a conventional HSS drill.

    The easiest way, but not the cheapest, is to purchase a special drill designed for making holes in hot metal. The cutting edges of such a tool are reinforced with victorious solders or are made of victorious inserts. In this case, it is also desirable to use additional cooling of the working area.

    When working with acids, you need to be extremely careful and perform the operation in a well-ventilated area. This will help prevent burns or poisoning from harmful vapors.

    How not to blunt the instrument?

    The tool becomes dull because it overheats during operation. To maintain sharpness, drilling should be done at low RPM. It is not necessary to clamp the power button of the tool all the way. When drilling thick workpieces, coolants or pastes must be used.

    If no cooling lubricant is available, machine oil can be used instead. Coolant keeps the tool from overheating, reduces friction.

    Drilling thick workpieces

    Not many novice craftsmen know how to drill a hole in thick metal. Deep drilling is more difficult than usual. In production, it is carried out using lathes. In them, the workpiece is fixed in a movable spindle, which rotates it.

    If you cannot use industrial equipment, you can drill a deep hole with a drill. To do this, you need to purchase special guides for the power tool. Additionally, the use of machine oil is required for cooling. In the process of work, you need to periodically stop to clean the chips and let it cool.
