Dry Cutting Diamond Core Bits

Blue BoarŪ dry diamond core bits provide a 10" drilling depth and vented barrels for heat relief, keeping the bits running cooler and providing for fast removal of cuttings. They have standard 5/8-11" threads for direct attachment. The Contractor series of diamond core bits offers excellent quality at an affordable price.

Dry cutting bits are ideal for electrical, plumbing, mechanical, HVAC and general contractors who need to make holes quickly in concrete block, brick, stone, tile. Dry core bits bore holes much faster than line drilling with conventional carbide tipped percussion bits, while providing a smoother finish, and with little or no patching.

The bit works without water, using either an inexpensive hand-held angle grinder or a hand held core drill. Cutting without water, these handy tools drill clean, neat holes.

**** Dry drilling of lightweight brick and block only. Dry core bits are not designed for drilling reinforced concrete or other hard, dense materials such as clay brick. ***
