Masonry bits are specifically designed for drilling into masonry, specifically concrete blocks, bricks, mortar or cast concrete. A masonry bit is really more like a cold chisel than a standard twist drill bit. The two tips on the end of the bit carve out small chunks of mortar, and the flutes carry the mortar out of the hole.
Insert the blunt end of the drill bit into your power drill or hammer drill and tighten the chuck.
Position the point of the drill bit at the center of the spot where the hole is to be drilled. Adjust the alignment of the drill so that the bit shaft is parallel to the desired path.
Slowly squeeze the drill's trigger, and begin drilling the hole slowly. Too much speed can cause the bit to wander.
As the hole begins to form, increase the drill's speed to quicken the drilling process.
Pull the drill bit out of the hole about once every inch of drilling to clear away the loose mortar from the hole.
Continue drilling until the desired depth is reached.
