Dormer Pramet A940 11/32 Inch HSS-E High Performance Multi-Application Straight Shank Long Series Drill DIN/ANSI is built for professionals who demand precision, reliability, and deep-hole capability in a single pass. This drill blends advanced geometry with durable HSS-E alloy to tackle a wide range of materials—from steel and stainless to aluminum—without compromising hole accuracy or edge life.

Key features that drive real-world results

• 130° point for quick, self-centering starts and reduced push force, helping you maintain straightness and minimize wandering at entry.
• Bright finish keeps material from sticking to the cutting edge, delivering cleaner holes and prolonging edge life in challenging workpieces.
• Parabolic flute design optimizes chip evacuation, enabling deeper holes in a single pass with smoother cutting action and less chatter.
• Premium HSS-E material offers excellent wear resistance and toughness, making it suitable for drilling a broad spectrum of metals including steel, aluminum, and stainless steel.
• Long series with straight shank (DIN/ANSI compatible) provides extended reach and secure, repeatable clamping in standard chucks and collets for consistent hole location, even in shallow or occluded work envelopes.
• High performance with tight tolerances designed to achieve high-quality, accurately sized holes at elevated speeds and feeds, with h10 hole tolerance to satisfy demanding engineering specs.

Ideal use cases and who benefits most

• Fabrication shops and machine rooms that require dependable, multi-material drilling in automotive, aerospace, and general engineering applications.
• Maintenance and repair environments where a single drill can handle steel, stainless, and aluminum without swapping tooling.
• Workholding scenarios where deep holes are needed in limited access areas, thanks to the drill’s long series and rigid straight shank.

Practical tips for best results

• Use an appropriate cutting fluid or coolant compatible with the workpiece material to maximize edge life and prevent overheating.
• Begin with a light pilot hole if starting in hard or gummy metals to improve penetration accuracy and reduce chatter.
• Maintain steady feeds and avoid excessive speed to preserve the 130° point geometry and flute effectiveness.
• Peck drilling in deep holes can help clear chips and reduce built-up edge, especially when drilling stainless steels or alloys with high toughness.

Designed to deliver reliable, repeatable performance across a variety of materials and production scenarios, the Dormer Pramet A940 drill is the go-to choice when you need a single tool that can handle multiple applications with precision, depth, and speed. Elevate your drilling workflow with a tool that combines thoughtful geometry, durable construction, and DIN/ANSI compatibility for seamless integration into any standard drilling setup.
