How to drill with a Masonry Bit


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.

Step One

Insert the blunt end of the drill bit into your power drill or hammer drill and tighten the chuck.

Step Two

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.

Step Three

Slowly squeeze the drill's trigger, and begin drilling the hole slowly. Too much speed can cause the bit to wander.

Step Four

As the hole begins to form, increase the drill's speed to quicken the drilling process.

Step Five

Pull the drill bit out of the hole about once every inch of drilling to clear away the loose mortar from the hole.

Step Six

Continue drilling until the desired depth is reached.
