Have you ever wondered why you take a lot of time to drill through concrete even when you have the right tools for the job? Drilling holes in concrete is a daunting task itself, but with the assistance of powerful tools like the hammer drill, the job should be easy. Therefore, if you find yourself spending hours doing the same thing, it is quite clear that there is something that you are not doing the right way. Whether you are drilling holes in a concrete wall to hang pictures or curtains, you must equip yourself with the following tips if you want to do the job quickly and efficiently.
1. Begin By Drilling Small Holes
If you have a small drill and you are intending to drill many large holes in concrete, it is better to begin by drilling small holes first, or what are known as pilot holes. You drill the small holes with the smallest drill bits that you have and then you expand the holes with larger drill bits. This will lessen the load on the drill and save you more time. But if the chuck -- the part where the drill bit is fitted -- can't accommodate a drill bit that is larger in size, do not try to force the drill bit in. It simply means that the machine wasn't made for such drill bits. So if you need to make holes that are larger than the largest drill bit your machine can take, you may have to try other options like using a rotary drill.
2. Do Not Exert Too Much Pressure
Applying too much pressure on your hammer drill does not make it drill faster. On the contrary, it might be slowing its speed. When you exert too much pressure on the tool, you may force the motor gears to suffer from wear and tear, which will only slow down your work. In addition to wear and tear of the gears, the drill bits may also break if excess pressure is applied on the tool. Applying the right pressure is not easy and usually comes with practice. But as a guide, the right pressure is the kind of pressure that is strong enough to prevent slipping of the tool, and tight enough to allow the tool to drill at a slow speed.
3. Always Remove The Debris
The drill bits are made with flutes that aid in pulling the debris from the hole. But you can clear the debris even faster if you pull the drill bit out of the hole from time to time when you are drilling. Less debris in the hole implies that there is less friction, and hence smoother drilling. Your drill bits will also last longer if they are not subjected to too much friction.
