1-1/4” x 18” Quad Head Simpson Strong-Tie SDS-plus Drill Bit

Contractor-grade quality is only one of the many benefits of the Simpson Strong-Tie SDS-Plus Shank MDPL12518Q Drill Bit 1-1/4” x 18” with Quad Head4x. Use this high-volume double-helix bit in various types of commercial construction. The SDS-plus shank features many enhancements, namely its chromium-nickel-molybdenum steel alloy body which improves ease of use, hammering quality and overall efficiency. Installers appreciate the centering tip for easy spot drilling, along with the uniformly brazed carbide inserts resulting in extended bit life.

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. Energy transfer is maximized with the patented, high-performance, reinforced core flute design. The SDS-plus shank works with the Titen Installation tool to allow pre-drilling and installation of Titen screws using a rotohammer. (Rotohammer must be in rotation-only mode before driving screws.) 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 1 SDS-Plus Shank Drill Bits.
