Dormer Pramet A940 2.30 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

Meet exacting micro-drilling performance with the Dormer Pramet A940 2.30 mm HSS-E High Performance Multi-App Straight Shank Long Series Drill. This ultra-precise drill bit is engineered for versatility across a wide range of metals, delivering clean, repeatable holes in demanding applications where precision matters as much as speed.

• 130-degree point promotes self-centering and reduces push force, helping you start holes with minimal wandering and improved first-pass accuracy.
• Bright finish minimizes workpiece material from sticking to the cutting edge, resulting in smoother chip evacuation and reduced risk of built-up edge during productive runs.
• Parabolic flute design enables deeper through-holes in a single pass, cutting drilling time and improving hole quality in machining setups with limited vertical clearance.
• Premium HSS-E material provides enhanced hot hardness and wear resistance, making the drill suitable for a variety of metals including steel, aluminium, and stainless steel.
• Straight shank, long-series construction ensures reliable gripping in standard chucks and extended reach for deeper hole drilling without compromising rigidity.
• DIN/ANSI compatibility means this drill fits a broad spectrum of machinery and tooling standards, reducing setup friction in mixed-work environments.
• High-speed, high-feed performance delivers consistently high-quality holes with h10 hole tolerance, supporting precise fits and reliable part-to-part repeatability even at elevated speeds.

This multi-application drill is ideal for precision drilling tasks in prototyping, fixture work, and production environments where small-diameter holes (2.30 mm) must be accurate, clean, and repeatable. Use cases include micro-assembly housings, electronics enclosures, and general fastener and alignment pilot holes across steel, aluminium, and stainless steel components. When choosing tooling for tight tolerances and repeatable results, the A940 line stands out for its balanced combination of point geometry, flute design, and material quality—delivering dependable performance where other micro-drills may falter.

With the A940, you’re selecting a long-series, straight-shank drill designed to stay true under high speeds and feeds while maintaining hole quality and dimensional accuracy. For best results, pair it with appropriate lubrication, steady feeds, and correct spindle speeds to maximize the HSS-E advantages and achieve precise, repeatable holes every time.
