DRILLS FOR CONCRETE:HOW TO CHOOSE THE RIGHT AND THE MOST IMPORTANT DRIVING TIPS
Concrete is a very hard and durable material, so if you need to drill holes in it, it is important to know that not any drill will fit. It is very important that the drill for concrete is harder than the drill bit, so a diamond drill will work best here. When choosing the most appropriate one, it is important to pay attention to the dimensions of the drill (it should be predetermined what diameter and depth the holes will be drilled), as well as the manufacturer of the drill and the price of this product. Some drills may only be suitable for wet or dry drilling, but universal drills are also commercially available.
IMPORTANT TIPS FOR DRILLING CONCRETE
When drilling in reinforced concrete, you often have to deal with reinforcement, so it is very important to prepare the drill for the metal. If you feel that the drill bit for concrete has been pressed into the reinforcement, disengage the punch and insert the drill bit into the metal. Once you have drilled the reinforcement, you will be able to re-insert the drill to the concrete;
⦁ Sometimes reinforcement drilling can be avoided. As it is part of the bearing structure, consider whether it is necessary to drill the reinforcement. It can be detected even before drilling starts – you can use a metal finder to do this;
⦁ After 15 minutes of continuous work it is recommended to take a break: periodically cooled drill usually lasts longer;
⦁ If the drill encounters an obstacle (such as stone) that the drill cannot overcome, it is best to remove it with a chisel;
⦁ Once drilled, drill bits can be sanded with a diamond blade, but it is important to know that this job requires some skill;
⦁ If the wall has to be drilled deep enough (25 cm or more), it is recommended to use two diameters drills: first with a smaller and thinner drill and then with a larger diameter;
⦁ When drilling walls, it is important to remove the plaster layer as it may hide electrical wiring or other wiring.
If you follow these guidelines, you will not only be able to drill faster, the drill will last even longer. If you are having trouble choosing the right drill, it is always good to consult with specialists who will help you find the right options.
