Which Masonry Bit do I select?

Masonry bits can be a complicated breed of drill bits. Below are the most common types and their distinct advantages & uses.

Fast Spiral


Generally used in rotary drilling. Speed range is 450-700 RPM to 1/2"" diameter, 350-500 RPM from 5/8" and up. Rotary bits do not break up the concrete, but actually grind it under operator pressure.

Rotary Percussion



Generally used in lightweight, mechanical vibrating hammers. Speed range 1300-3500 RPM, at up to 50,000 blows per minute. The impacting action created by the hammer fractures the concrete into tiny granules.

Rotary Hammer



Used in electro-pneumatic rotary hammers. Speed range 400-1000 RPM at up to 4500 blows per minute. SDS+ is currently the most popular shank type for holes up to 5/8”. Spline and SDS-max for holes 3/4" and larger.

Rebar Cutter



Used to cut holes through embedded steel reinforcing bar. It is used to prevent damage to the hammer bit, which occurs if the hammer bit is used after rebar is encountered.

Core Bit



The most effective way of drilling a large hole since you are only cutting the circumference. Both rotary and hammer types are available. Rotary core bits require a great deal of pressure and are suitable for very brittle or thin materials. Hammer core bits offer speed and economy only if rebar is encountered.
