Dormer Pramet A940 10.30 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

Dormer Pramet A940 10.30 mm HSS-E High-Perf Multi-App Straight Shank Long Series Drill DIN/ANSI is built for professional metalwork where precision, reach, and reliability matter. This long-series drill combines a deliberate geometry with advanced coating and material science to deliver clean, accurate holes across a range of metals, in a single, efficient pass.

• 130-degree point for self-centering starts every hole with minimal effort, reducing push force and ensuring you get true locations from the first cut.
• Bright finish minimizes workpiece material adhesion to the cutting edge, delivering smoother starts and easier chip evacuation in challenging workpieces.
• Parabolic flute design enables efficient chip removal and allows deeper holes to be drilled in a single pass, improving productivity on long-hole applications.
• Premium HSS-E construction provides robust performance across a variety of materials, including steel, aluminum, and stainless steel, while maintaining service life under demanding speeds and feeds.
• High-performance drilling capabilities support high speeds and feeds with consistent hole quality, meeting H10 tolerance for precise, repeatable results.
• DIN/ANSI straight shank and long-series design offer compatibility with a wide range of drill chucks and fixtures while providing extended reach for deep cavities and hard-to-reach locations.

This drill is an ideal choice for manufacturing and workshop environments where versatile metalworking is required—from rapid pilot holes in steel assemblies to through-holes in aluminum components. The A940 excels in multi-material drilling, enabling consistent performance whether you’re fabricating machinery frames, automotive fixtures, or stainless-steel assemblies.

Key benefits at a glance:

• Enhanced starting accuracy with a precision 130° point minimizes repositioning and rework.
• Less material sticking and smoother entry thanks to a bright, low-friction cutting edge.
• Efficient deep-hole capability in a single pass, reducing cycle times and tool changes.
• Reliable HSS-E durability for frequent use at higher speeds and feeds while preserving hole integrity.
• Wide compatibility with DIN/ANSI tooling and a long-series design for hard-to-reach drilling scenarios.

Practical tip: for optimal results, match cutting speed and feed rate to the workpiece material and thickness, and use appropriate lubrication or coolant to prolong tool life and achieve the best H10-hole tolerance consistently.
