9/16” x 21” Simpson Strong-Tie SDS-max Drill Bit

The Simpson Strong-Tie SDS-max Shank Drill Bit MDMX05621 9/16” x 21” with 2-Cutter head is the premium quality, professional-grade tool to best suit your pre-drilling concrete & masonry needs. The SDS-max drill bit includes a variety of new features that enhance its durability and drilling speed, while improving the ease of use. Professionals appreciate the centering tip featured on most SDS-max bits that facilities easy spot drilling. Product quality and bit life is extended on this premium tool by its chromium-nickel-molybdenum steel alloy body and uniformly brazed carbide inserts.

Manufactured with strength and durability, SDS-max drill bits have a strong 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 this bit highly efficient as its patented, high-volume, multi-flute spiral quickly channels concrete dust from the hole, improving drilling speed 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 as this product conforms to ANSI Standard B212.15. The SDS-max bit comes as a box quantity of 1. Order today from Nail Gun Depot.
