Tools Direct Dry Cut Diamond Core Bits are ideal when drilling holes in cured concrete, brick, block, and stone. Dry Cut Diamond Core Bits have turbo segments and a thinner wall allowing for superior drilling speed. They are 10" long and have standard 5/8"-11 threads. Perfect for using on a rig or with a hand-held tool.
Use wet or dry. Dry Core Bits can be used with hammer drills - see our FAQ #3.
Dry Core Bits can be used with hammer drills provided you have: 1) the correct adapter and 2) a setting on your drill for spin only (the hammer action will blow the diamonds right off the bit, making it useless).
