Dormer Pramet A117 4.10 mm HSS-E STRAIGHT SHANK STUB DRILL DIN 1897

The Dormer Pramet A117 4.10 mm HSS-E Straight Shank Stub Drill (DIN 1897) is a compact, cobalt-enhanced drill designed for precise metal drilling. Its straight shank fits most standard chucks, making it a versatile choice for workshops, fabrication shops, and serious hobbyists. Built for reliability, it delivers consistent hole quality across a range of materials.

With a 135-degree split point and bronze oxide finish, this drill starts quickly and cleanly, reduces wander, and minimizes built-up edge that can mar finishes. The result is accurate holes with smoother edges and less finishing work.

• 135° Split Point for Self-Centering and Easy Starts: Self-centering tip reduces wandering and lowers the push force required, helping you start holes accurately and drill faster with less effort.
• Bronze Oxide Finish for Reduced Sticking: The bronze oxide coating helps prevent material from sticking to the cutting edge, cutting friction and extending tool life in challenging metals.
• Premium HSCO Material with Heavy-Duty Design: HSS-E with cobalt (HSCO) delivers enhanced hot hardness and wear resistance, enabling drilling into hard materials such as tool steel while maintaining form and a robust straight shank for demanding applications.

With this drill, you gain reliable performance, reduced downtime, and consistent results that you can count on for both professional manufacturing and skilled DIY work. Its DIN 1897 standard ensures interchangeability with other tools, enabling quick replacements and efficient workflows across your milling or drilling setups.
