Tools Direct Dry Cut Diamond Core Bits are ideal when drilling holes in brick and block pass through applications. These diamond core bits also work well with cured concrete. Dry Core Bits are 10" long and have standard 5/8" -11 threads. They are designed to be used with a hand-held tool.
Use wet or dry.
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).
