In this article we will tell you how to properly drill various materials with a drill: metal, tile, concrete, glass, wood. Work with wood, metal, concrete and tile has its own subtleties. If you follow some principles, then the holes will be smooth and high quality.
To properly drill metal, you need to know the properties of this material. It is very hard, hard to mechanical stress and requires drill bits of a certain strength. If the drills are bad, then the job will not work. Saving on a tool is not recommended because a poor, poor-quality tool can destroy the material.
Drilling thin metal sheets is a real flour for most craftsmen. Steel tends to break free, which can lead to serious injuries. To prevent this from happening, the steel sheets must first be fixed. To do this, you can make a special device that will clamp steel.
For even holes, a piece of rubber should be placed under the steel sheet. It is noted that when drilling large holes, the steel around can collapse, creating scars. Rubber will prevent this.
When cutting blind threads, various debris often gets into the hole. To eliminate this phenomenon, it is necessary to pour a little paraffin or wax inside.
Tile is a very fragile material. Incorrect movement. and it can just crack. To properly drill the tile, you need to follow simple rules. First of all, you need to pick up special drills that have brazed carbides. This will reduce the load on the work surface and facilitate the drilling process.
The point where you need to make a hole must be marked in advance. This is done with a tap or marker. This point will ensure that the drill does not slip. A mark is made on the outside of the tile.
Sometimes it is necessary to drill a tile that is already glued to the surface. In this case, you can use drills for glass. When drilling tiles, there are no special secrets. The main thing is not to exert too much effort, otherwise the tile will crack. The better the drill, the easier the work process is.

Drill Bits Holes in concrete may be needed for a wide variety of purposes. The need for them may arise during normal repairs. For example, holes in a concrete wall are required when installing a toilet bowl and other plumbing, for installing shelves and sliding doors. There are lots of examples when you need to use a drill to work with this material. Concrete has its own special properties, therefore, work with it is also carried out according to certain rules.
How to drill concrete? For this purpose, you need to purchase drills with victorious tips.
It must be remembered that the drill is used in concrete work only for drilling holes of small diameter (up to 12-13 mm). If you need to make a larger hole, it is better to use a hammer drill.
When drilling concrete, the most common problems are drill breakage and jamming. Drills can also become clogged, so they need to be cleaned and sharpened regularly.
Dust will not fly in all directions if you put a box or a can on the drill while drilling a hole. Then, during operation, concrete dust will collect in the tank.
Drilling is as follows:
- First, a point is marked at which a hole will be made.
- Then you need to make a small recess at this point with a conventional drill.
- Is the deepening ready? So, it’s time to change the usual drill to asymmetric. It will allow you to work more efficiently.
- If the hole is made under the dowel, then it must exceed its size. Because concrete dust will significantly reduce free space.
- It is better if the drill used in the work has a built-in level. Anyone who has already drilled concrete knows how difficult it is to constantly maintain an even position of the tool. Especially if the work is long.
- Drills during operation can be regularly moistened with plain water. This makes the process easier.
Wood is a soft, natural material that lends itself perfectly to mechanical stress. However, in working with wood, a number of rules must be observed.
- When making holes in logs, it is better to fix the material. Because otherwise the master risks losing the drill.
- If you need to make holes in small pieces of wood, then under them you can put the usual emery. Then the parts will not slip.
- Burrs can be removed after drilling by wrapping felt around the drill.
- Wood has many varieties, and each of these varieties contains its own characteristics. For example, plywood is almost impossible to drill, it can easily crack. To avoid this, it is necessary to use not ordinary drilling, but a tool that resembles the appearance of a potato peeler. If you sharpen a steel tube, you can use it to make many great holes in plywood.
When working with wood, it is not the drill that suffers more often, but the wood itself. Do not press too hard on the material, some types of boards may crack or crack as a result. This is especially important when making large holes. Drills for wood are suitable from among the inexpensive.
