Dormer Pramet A117 2.30 mm HSS-E STRAIGHT SHANK STUB DRILL DIN 1897

The Dormer Pramet A117 2.30 mm HSS-E Straight Shank Stub Drill (DIN 1897) is a compact drill bit designed for precise metal drilling in challenging materials. With a straight shank and DIN 1897 specification, it fits most standard drill chucks and holders, making it a versatile tool for engineers, machinists, maintenance technicians, and hobbyists who need reliable, first-pass hole quality.

Built for durability and steady performance, this 2.30 mm stub drill delivers clean holes, tight tolerances, and long tool life even when working with hard metals.

• 135° Split Point for Self-Centering: The precision tip starts holes accurately and reduces push force, helping prevent wandering and improving first-pass hole quality across a range of metals.
• Bronze Oxide Finish for Reduced Sticking: The bronze oxide coating minimizes material adhesion to the cutting edge, resulting in smoother drilling, less built-up edge, and easier chip evacuation for cleaner holes.
• Premium HSCO Material with Heavy-Duty Design: Crafted from cobalt-enhanced HSCO material to handle hard materials (including tool steel) with longer life, while the heavy-duty construction supports demanding applications and consistent performance.

This drill bit is designed to improve your workflow by delivering accurate holes on the first pass, minimizing rework and finishing time. Its 2.30 mm diameter is ideal for precision work, pilot holes, and delicate metal projects, while the DIN 1897 compatibility ensures quick tool changes with standard holders. The combination of self-centering action, anti-stick coating, and robust HSCO construction translates to reliable results, fewer interruptions, and consistent performance across jobs.
