13/16” x 21” Simpson Strong-Tie SDS-max Drill Bit

Professionals love the new contractor-grade Simpson Strong-Tie SDS-max Shank Drill Bit MDMX08121Q 13/16” x 21” with Quad Head4x. This premium quality, professional-grade tool is ideal for concrete & masonry installation projects. The SDS-max drill bit incorporates a variety of features that enhance its durability and drilling speed, while improving the ease of use. The centering tip featured on most SDS-max bits is a plus for installers because it makes spot drilling nice and easy. Product quality and bit life is extended on this premium device by its chromium-nickel-molybdenum steel alloy body and uniformly brazed carbide inserts.

Designed with strength and reliability, SDS-max drill bits are heat-treated with a shot-peened finish for a strong resistance to bending forces and wear. The finish on these bits simultaneously increases drilling speed and surface hardness. 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. The MDMX08121Q conforms to ANSI Standard B212.15. It is sold as a box quantity of 1. Drill with confidence using the SDS-max Shank Drill Bit.
