The Simpson Strong-Tie SDS-max Shank Drill Bit MDMX06221Q 5/8” x 21” with Quad Head4x, is a professional-grade tool ideal for concrete & masonry projects.

Professionals appreciate the centering tip featured on most SDS-max bits that facilities easy spot drilling. SDS-max drill bits incorporate a variety of new features that enhance durability and drilling speed, while improving ease of use.

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. The SDS-max drill bit conforms to ANSI Standard B212.15 and is sold as a box quantity of 1. Order today from Nail Gun Depot and begin your new premium drilling experience.
