Dormer Pramet A940 3.70 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

Introducing the Dormer Pramet A940 3.70 mm HSS-E High Performance Multi-Application Straight Shank Long Series Drill DIN/ANSI — a precision drill built for consistent, high-quality holes across a range of metals. This 3.70 mm drill combines advanced geometry with a cobalt-enriched alloy to tackle tough materials without sacrificing accuracy or speed.

• 130-degree point for confident self-centering entry and reduced push force, helping you start holes cleanly and maintain control from the first instant of contact.
• Bright finish minimizes buildup on the cutting edge, reducing chip adhesion and extending tool life by preserving sharpness during long runs.
• Special parabolic flute design optimizes chip evacuation, enabling deeper holes in a single pass and maintaining a smooth hole wall even at higher feeds.
• Premium HSS-E material (cobalt-enriched) delivers greater hardness and heat resistance, making the drill versatile for steel, aluminum, and stainless steel without sacrificing performance.
• High-performance drilling capabilities support high speeds and feeds while achieving high-quality, accurate holes with tight tolerances (H10).
• Long-series, straight shank design with DIN/ANSI compatibility ensures reliable, repeatable performance in standard tool holders, ideal for production environments demanding consistency.

This drill is specifically suited for operators who need a single tool that can handle multiple materials while delivering excellent hole quality, even in deep drilling scenarios. The A940’s geometry and coating-free finish work together to reduce chatter, improve straightness, and maintain edge sharpness over extended usage, making it an essential addition to any precision drilling toolkit.

Ideal applications include fabrication and machining tasks where precision is non-negotiable — from automotive components and sheet metal assemblies to thick steel plates and stainless panels. For best results, pair the drill with appropriate speeds and feeds for the material, ensure solid work-holding to prevent deflection, and rely on the straight shank for dependable clamping in standard chucks and collets.
