Dormer Pramet A117 4.80 mm HSS-E STRAIGHT SHANK STUB DRILL DIN 1897

The Dormer Pramet A117 4.80 mm HSS-E Straight Shank Stub Drill (DIN 1897) is a compact, high-performance drill bit designed for metalworking where small, precise holes are required. With a straight shank and stub length, it delivers steady rigidity on drill presses and machining centers, making it ideal for engineers, fabricators, hobbyists, and maintenance technicians who demand reliable hole quality.

Its 135-degree split point promotes self-centering and reduces starting push force, helping you start holes cleanly and stay on target. Combined with a bronze oxide finish that minimizes material sticking and a robust HSCO-grade composition, this drill handles hard materials including tool steel with confidence.

• 135° split point for easy starting and self-centering: The split point concentrates cutting energy at the edge, reduces wandering, and lowers the force needed to begin drilling for cleaner entry.
• Bronze oxide finish to prevent sticking: The protective coating helps prevent workpiece material from adhering to the edge, improving chip flow and extending edge life.
• Premium HSCO material with heavy-duty design for hard materials: Built to drill hard metals, including tool steel, with reliable performance and durability in demanding applications.

This combination delivers precise, repeatable holes with minimal rework, fitting smoothly into production runs or on-demand fabrication. The 4.80 mm diameter is ideal for pilot or through holes, and theDIN 1897 specification ensures compatibility with a wide range of standard drills and housings, helping you achieve consistent results across different setups.
