Dormer Pramet A920 5.50 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK STUB DRILL DIN/ANSI

The Dormer Pramet A920 5.50 mm HSS-E Straight Shank Stub Drill is a versatile, high‑performance drilling tool designed for precise metal holemaking. With a 5.50 mm diameter and a DIN/ANSI straight shank, it fits standard chucks and tooling setups for reliable performance in both production environments and DIY workshops. Built for consistent results, it handles a variety of materials with ease.

Designed for practical reliability, this drill combines a 130° point for self-centering starts, a bright finish to minimize sticking, and a parabolic flute design that enables deeper holes in a single pass. Together with premium HSS‑E material, it delivers smooth, accurate holes at higher speeds and feeds across multiple metals.

• 130° Self-Centering Point: Promotes precise starts, reduces wanders, and lowers push force for easier, more accurate hole initiation.
• Bright Finish for Reduced Buildup: Keeps the cutting edge clean, improves chip flow, and minimizes material sticking for cleaner holes and longer tool life.
• Parabolic Flute Design with HSS‑E Core: Enables deeper holes in a single pass while delivering consistent, high-quality holes in steel, aluminium, and stainless steel—even at higher speeds and feeds.

With premium HSS‑E material and thoughtful geometry, the A920 drill supports reliable performance across a wide range of applications. Expect precise hole diameters to tight tolerances (H10), reduced downtime from fewer tool changes, and smoother workflow in production runs, maintenance tasks, and precision assemblies.
