Dormer Pramet A920 8.50 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK STUB DRILL DIN/ANSI

The Dormer Pramet A920 8.50 mm HSS-E High Performance Multi-Application Straight Shank Stub Drill (DIN/ANSI) is a versatile cutting tool designed to tackle a wide range of metals with a single, reliable drill. With an 8.50 mm cutting diameter and a straight shank, it's a great fit for standard drill presses and CNC machines in busy workshops.

Built from premium HSS-E, this drill combines precision with durability. Its 130-degree point helps start holes with minimal wandering, the bright finish reduces workpiece sticking to the edge, and the parabolic flute design clears chips efficiently for deeper holes in one pass. It delivers high-quality, accurate holes even at higher speeds and feeds, with H10 hole tolerance for predictable results.

• Parabolic flute design for deeper holes: The parabolic flute guides chips smoothly, enabling deeper holes in a single pass and improving hole quality while reducing cycle time.
• 130° point for self-centering and reduced push force: The 130-degree tip starts cutting cleanly, minimizes wandering, and lowers effort during setup and drilling.
• Premium HSS-E material with bright finish for versatile, reliable drilling: Engineered to drill steel, aluminium, and stainless steel with consistent results; the bright finish minimizes sticking and supports high-speed, high-feed applications with tight H10 tolerances.

This combination delivers a dependable, multi-material drilling solution that speeds up workflows, improves hole quality, and reduces downtime from tool changes. The A920 8.50 mm stub drill offers consistent performance across common metals, robust durability, and compatibility with standard DIN/ANSI tooling—giving engineers, technicians, and hobbyists a single, trusted tool they can rely on for demanding jobs.
