#### PRODUCT OVERVIEW

Professionals enjoy using the Simpson Strong-Tie SDS-Plus Shank MDPL03706-R25 Drill Bit 3/8” x 6-1/4” with 2-cutter head for use in commercial construction. This quality bit has a centering tip for easy spot drilling, and uniformly brazed carbide inserts which result in extended bit life. Engineered with many enhancements, the SDS-Plus Shank has a chromium-nickel-molybdenum steel alloy body which improves ease of use, hammering quality and overall efficiency.

This bit comes heat-treated with a shot-peened finish to increase surface hardness, while reducing drill bit wear and improving its bending resistance. It’s manufactured for efficiency with a chisel-shaped head that easily penetrates material while preventing sticking in concrete and removing dust upon use. Drilling speed is amplified on this bit with a patented, high-volume, multi-flute spiral. This compatible bit fits all current and older SDS-plus rotohammers from AEG, Black & Decker, Bosch, DeWalt, Hitachi, Hilti, Kango, Makita, Metabo, Milwaukee, Porter Cable, Ramset, Red Head, Ryobi and Skil. Conforms to ANSI Standard B212.15. Package includes 25 SDS-Plus Shank Drill Bits.
