The Dormer Pramet A117 8.40 mm HSS-E Straight Shank Stub Drill (DIN 1897) is a compact, high-performance drilling solution designed for precise metalworking. Its straight shank and DIN 1897 specification ensure compatibility with a wide range of chucks and holders, making it a versatile choice for workshops, fabrication shops, and maintenance teams.
Equipped with a 135-degree split point, bronze oxide finish, and premium HSCO (high-speed steel cobalt) construction, this drill delivers reliable starts, reduced start-up effort, and outstanding wear resistance when cutting hard materials—including tool steel—while maintaining a smooth, consistent hole quality.
- 135° Split Point for Self-Centering: Enables clean starts with less wandering and reduces the push force required, helping you drill accurate holes with less effort.
- Bronze Oxide Finish for Reduced Build-Up: Minimizes material sticking to the cutting edge, improving chip flow and delivering smoother drilling and less rework.
- Premium HSCO Material with Heavy-Duty Design: Combines wear resistance and toughness to handle hard materials and demanding applications, delivering longer tool life and consistent performance.
This drill bit is built to improve workflow reliability, delivering repeatable hole quality and reducing downtime in challenging drilling tasks. Its robust design, combined with the asset of a standard straight shank and DIN 1897 compatibility, makes it a dependable choice for engineers, machinists, and hobbyists tackling tough metals with confidence.
