Blue Boar™ Dry Cutting Diamond Core Bits from Hole Pro®

For holes over 1-1/2" in diameter, core bits offer advantages over solid-body bits. They drill faster because they drill only the circumference of the hole instead of removing all of the material.

Dry cutting core bits are ideal tools for electrical, plumbing, mechanical, HVAC, or general contractor needing to make a hole quickly and cleanly for an installation.

The dry core bits work without water, using either an inexpensive hand-held right angle grinder or a standard hand held core drill. Without water, these handy tools drill clean, neat holes quickly, and without the setup and cleanup time associated with using a water-cooled drilling rig.

The Blue Boar Laser-Welded diamond cutting segments provide longer life than brazed segments or turbo segments and are designed to withstand the higher temperatures generated with dry cutting and the use of angle grinders with their higher operating RPM’s.
