Dormer Pramet A920 5.90 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK STUB DRILL DIN/ANSI

The Dormer Pramet A920 5.90 mm HSS-E high-performance multi-application straight shank stub drill is designed for precise, repeatable hole quality across a range of materials. Built to DIN/ANSI standards, it’s an ideal choice for engineers, machinists, tradespeople, and DIY enthusiasts who need reliable, accurate drilling in a compact tool.

The 130° point helps with self-centering and reduces the push force required to start the hole. A bright finish prevents workpiece material from sticking to the cutting edge, improving chip flow and reducing binding. The special parabolic flute design enables drilling deeper holes in a single pass, boosting productivity without sacrificing accuracy. Made from premium HSS‑E, this drill is suitable for steel, aluminium, and stainless steel while maintaining high quality and an H10 tolerance at high speeds and feeds.

• 130° point for self-centering: The 130-degree geometry starts holes cleanly with less resistance, reducing push force and improving first-pass accuracy across common metals.
• Bright finish reduces sticking: The bright surface minimizes material adhesion on the cutting edge, aiding chip flow and tool life in busy drilling environments.
• Parabolic flute design with premium HSS‑E: The parabolic flute enables deeper holes in one pass, while the HSS‑E composition delivers consistent, high-quality results in steel, aluminum, and stainless steel, even at higher speeds and feeds (H10 tolerance).

Designed for reliability, this drill supports faster, more predictable workflows. The straight shank guarantees compatibility with a broad range of machines, and the durable HSS‑E construction stands up to demanding tasks across multiple materials. Whether you’re manufacturing, performing maintenance, or prototyping, you’ll achieve clean, accurate holes with confidence.
