HSS-E twist drill DIN 338 Type N, short, fully ground, with split point, 5% cobalt-alloyed 135°
HSS-E twist drills to DIN 338 Type N in short design are engineered for demanding materials such as stainless, heat-resistant and tough steels. With 5% cobalt content, they offer significantly improved hot hardness and tool life compared with standard HSS-G drills. The fully ground geometry and 135° split point ensure smooth running, low feed pressure and clean, burr-free holes. The short length increases rigidity and reduces the risk of breakage, especially when drilling by hand or in confined spaces. They are ideal for machine building, metal fabrication, assembly and maintenance wherever high process reliability and accurate holes in difficult materials are required.
