5/16" X 4-1/4" PRO Series SDS-Plus 4-Cut Tip Hammer Bit Drill Bit SDSPRO4F5/16X4-1/4

The SDS PRO Series 4-Cut Hammer Drill Bit is engineered for maximum performance in concrete and reinforced materials. Featuring four precision-ground cutting edges and a four-helix flute design, it delivers fast drilling speeds while efficiently removing debris to minimize dust buildup and blowback. The advanced carbide tip, combined with an optimized head geometry, allows for faster penetration in concrete and superior durability when drilling through reinforcement. Compared to previous models, it offers up to 10% faster drilling, is three times more robust in rebar, and provides twice the service life. The SDS-plus shank ensures a secure, slip-free connection with compatible rotary hammers for optimal energy transfer. A patented double-centering tip ensures stable starts and precise, user-friendly drilling—even in the most demanding applications.
