How to use the drill’s function or mode?

Most rotary hammer drills come with three modes or functions drill-only mode, hammer-only mode, and hammer/drill mode. You can change the function in accordance with your requirement.

  1. Drill Only Mode: If you want to use your rotary hammer drill for drilling into steel, wood, or widening holes then you have to select the “Drill only” mode.
  2. Hammer Only Mode: If you want to chisel tile or remove mortar or burst small areas of concrete or hammer away surfaces then you have to use the “hammer only” mode. Basically, where the shaft doesn’t require rotation, you can select this “hammer only” mode and use the rotary hammer as a mini-jackhammer.
  3. Hammer/Drill Mode: In fact, all the rotary hammer drills come with the “Hammer and Drill” mode as a default function and it’s the most useful function of the rotary hammer drill. If you want to drill into concrete, rock, packed clay, or masonry then you have to use this “Hammer and Drill” mode.

It’s much easier to use your rotary tool on horizontal surfaces including ground or floors compared to use on vertical surfaces. Because you don’t need to hold the tool against the vertical wall or column. But here also you have to hold the tool straight and securely.

However, here are the 05 steps on how you can use your rotary hammer on horizontal surfaces:

  1. Insert the drill bit or install the necessary tool accessories. If you want to put in small anchors, then it will be better to use quite a smaller SDS or SDS Plus bit. On the contrary, if you would like to put in lag bolts, you have to use longer 16-inch bits. Grease the bit shank before inserting properly.
  2. Wear your safety gear including eye protection, hand gloves, etc. Though the rotary hammer drill is comparatively a safe tool as it uses low RPMs, it will be wise to use at least eye protection.
  3. Select the mode “Hammer Only” for chipping and digging or “Drill and Hammer” mode for drilling holes.
  4. Aim the tool at the object point and hold it securely using both hands. Then, press the trigger to let the tool work and you just hold it in the right position until it finishes its drilling.
  5. After use, let the tool cool down and then release the bit and clean it properly. If it’s corded, then unplug it from the power source and keep it in the right place.
