The SDS-max drill bit incorporates a variety of new features that enhance its durability and drilling speed, while improving the ease of use. Product quality and bit life is extended on this premium tool by its chromium-nickel-molybdenum steel alloy body and uniformly brazed carbide inserts. Professionals appreciate the centering tip featured on most SDS-max bits that facilities easy spot drilling. SDS-max drill bits have a tough resistance to bending forces and wear, as they’ve been heat-treated with a shot-peened finish. The finish on these bits simultaneously increases drilling speed and surface hardness as well. Ease of use is amplified with a chisel-shaped head that easily penetrates material. The 4 x 90° head geometry crushes through rebar to prevent sticking in concrete. You’ll find the high-volume, double-helix design of this quad-head bit highly efficient as its patented, high-performance, reinforced core flute maximizes energy transfer upon use. This compatible bit fits all current and older SDS-max rotohammers from Black & Decker, Bosch, DeWalt, Hitachi, Hilti, Kango, Makita, Metabo and Milwaukee. Drill with confidence knowing the SDS-max bit conforms to ANSI Standard B212.15. This product is sold as a box quantity of 1.
