Product Description

Built for the Tough Jobs, the fewer segments of the C-51 make for a faster drilling in high psi concrete, heavy rebar reinforcement, and hard aggregate.

Specially formulated segments – C-51 bits contain high concentrations of quality diamonds combined with a special blend of metal powders to deliver maximum performance with lowest drilling costs. Improved cooling and slurry removal. The double pointed segments increase water flow to reduce heat and removed slurry more efficiently. Fast seating and reduced vibration. The double-pointed tips penetrate quickly and hold a straight drilling path to reduce side drag. Reduced vibration improves drilling efficiency and bit life. Faster drilling. The double-pointed segments provide incredibly fast drilling speeds.
