Round- and Hex-Shank Masonry Drill Bits for Rotary-Only Drilling
Instead of using a hammering action to break up masonry material, these bits drill with rotary action only, requiring more pressure to grind up material. Use with handheld power drills, drill presses, and in hammer drills set to rotary-only mode. Do not use in hammering applications.
When using bits with a maximum drilling depth of 10 1/2” or greater, take the bit out of the hole every 4” and remove debris before drilling deeper to achieve maximum drilling depth.
