A quality hammer drill can bore down over two inches in solid concrete in one moment, which is significantly speedier than any rotary drill. These tools work by cracking the material through a fast hammer activity and after that scooping out the broken rock and dust through drilling.
Stage 1. Prepare the Drill Bit
Use a pencil to mark on the concrete where you need to drill your hole, and twofold check each estimation before proceeding onward. This is also a decent time to determine how profound you need each drilled hole to go.
If included, you can use the drill’s stop bar to set the exact depth you need each hole to be. Try not to stress if there isn’t a stop bar; simply wrap a bit of tape around the drill bit at the coveted length.
Stage 2: Get in Position
Put on safety goggles (and your favorite construction work clothes!) and embed your drill bit into the drill. Get into a safe drilling position by standing upright, with the tool secured in the two hands. Construction safety gear.
The best hand position is to hold your drill like a handgun and keep a grip on the helper handle for additional control. To ensure you get a straight hole, the drill bit should be impeccably opposite to the concrete before you start.
Stage 3. Make a Guide hole
Turn your drill to the most reduced setting, and work to put it plainly, controlled blasts to make a guide hole about a ¼ inch profound. This will build the drill’s stability as you drill the good hole.
Stage 4. Begin Drilling!
Carefully put the drill into the guide hole and start drilling down with a consistent hand. You can turn the speed up if you feel sure, drilling down into the concrete until the point that you achieve the stop bar or scotch tape.
Keep as a top priority that concrete is loaded with air pockets and little rocks that can quickly change the resistance level of your drill, making it simple to lose control if you aren’t careful. Never constrain the tool through if you hit obstructions, as it can damage the bit or cause you to lose control and damage the concrete surface.
Stage 5: Remove the Dust
As you drill, you should intermittently stop to haul out the tool and brush away the developed concrete dust. Pausing your progress like clockwork is a quick thought, and it also keeps the rotary hammer from overheating.
Stage 6: Finish the Hole
Once you’ve achieved the correct depth for your hole, haul out the drill and victory any residual dust with packed air, following a short time later with a vacuum to get everything that tumbles to the ground.
Wearing your safety goggles is as yet significant amid this progression, as concrete dust is highly irritating to the eyes.
Stage 7. Begin the Next Hole
You can rehash this process for each hole you have to drill, giving the hammer drill enough time to chill off between holes to avert problems.
In so far as you are careful and make precise estimations, you’ll be flabbergasted how basic it is to drill concrete when you have tools sufficiently powerful to finish the activity.
