The tool’s powder metallurgy HSS‑E core combines toughness with a sharp cutting edge for extended life in demanding materials. The 30° helix and 12° rake are designed to optimize chip formation and reduce built‑up edge, promoting smoother cuts and better surface finish. A robust 12 mm Weldon shank provides rigid alignment in holders, which is especially beneficial for the short, compact geometry of this drill. With a 16 mm depth of cut and a 27.5 mm reach, you can reach pockets and shoulders efficiently while maintaining precise geometry and control.
