Why not use a Dry Masonry Core Bits in Drilling?

A perfect circle is never created by chance or by luck, and this holds true most especially in the world of construction. While in the past, spear-point bits worked wonders in creating holes, these old-fashioned tools can no longer penetrate through new types of materials. Enter diamond core bits, a diamond blade tool used for drilling concrete, blocks, bricks, tiles, granite, marble, porcelain, stone, and other hard aggregate materials. A perfect circle or a perfect core can be seamlessly created through top-grade diamond core bits.

For wet / dry cutting. 9" tube length with Laser-Welded individual segments to hold up under extreme heat and cutting pressure. Barrel vents increase air flow to dissipate heat and cool the core bit. Specially formulated professional quality segments provide fast cutting and long life. For general purpose dry drilling on a variety of soft brick and concrete block. NOT RECOMMENDED for Concrete and Reinforced Concrete.
