Dormer Pramet A117 9.10 mm HSS-E STRAIGHT SHANK STUB DRILL DIN 1897

The Dormer Pramet A117 9.10 mm HSS-E Straight Shank Stub Drill (DIN 1897) is designed for clean, accurate holes in metal, especially when access is limited or depth is short. Built for reliability in demanding applications, it delivers consistent performance across a range of materials.

Its 135° split point centers the drill quickly, reducing starting force, while the bronze oxide finish helps prevent sticking and flare-ups during cutting.

• 135° Split Point for Self-Centering: Starts holes quickly with minimal wandering, reducing push force and improving first-pass accuracy.
• Bronze Oxide Finish for Reduced Sticking: Inhibits material from bonding to the cutting edge, delivering cleaner holes and smoother chip flow.
• Premium HSCO Material with Heavy-Duty Design for Tough Materials: High-speed steel with cobalt delivers enhanced wear resistance; the robust geometry is built for hard materials including tool steel and demanding applications.

With its DIN 1897 compliance and 9.10 mm diameter, this drill is ready for production lines, job sites, and serious workshops. The combination of a self-centering point, anti-sticking bronze oxide coating, and a durable HSCO formulation translates into faster setup, longer tool life, and consistently high-quality holes. Whether you’re drilling tool steel, hardened alloys, or other challenging metals, the Dormer Pramet A117 delivers reliable performance, reduces downtime, and helps you finish projects on time.
