Dormer Pramet A940 1.60 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

The Dormer Pramet A940 1.60 mm HSS-E High Perf Multi-App Straight Shank Long Series Drill DIN/ANSI is engineered to deliver dependable, high-precision holes across a wide range of materials. Built for production environments that demand consistent results from first pass to final depth, this drill blends refined geometry with durable construction to keep your machining process flowing smoothly.

Key features that drive real-world results

• 130° point for self-centering starts – The precise point geometry minimizes wandering at entry, reducing push force and helping you achieve true starts even on challenging workpieces.
• Bright finish reduces-built up edge – A polished cutting edge resists material sticking, promoting cleaner holes and easier chip evacuation across ferrous and non-ferrous metals.
• Parabolic flute design for deep-hole capability – The optimized flute geometry enables deeper holes in a single pass, cutting cycle times and lowering tool wear by maintaining efficient chip flow.
• Premium HSS-E material – Heat- and wear-resistant, this high-speed steel family extension provides reliable performance across steel, aluminum, and stainless steel workpieces, even at demanding speeds.
• High-speed, high-accuracy drilling – Designed to sustain quality holes at elevated speeds and feeds, the drill achieves tight tolerances (h10) without sacrificing surface finish or diameter control.
• DIN/ANSI straight shank, long-series design – Proven compatibility with standard drill chucks and holders, while the extended flute length supports deeper drilling tasks in a single setup.

Who benefits most

• Machine shops and job shops performing multi-material drilling (steel, aluminum, stainless steel) with frequent changes in part geometry.
• CNC operators and manual machinists who value consistent hole quality, reduced cycle times, and predictable tool life.
• Specifically suited for applications requiring deep holes, precise hole geometry, and dependable performance in DIN/ANSI environments.

Practical usage tips

• Pair with appropriate cutting fluid or coolant to maximize tool life and surface finish, especially when drilling stainless steel.
• Maintain proper feeds and speeds according to material type to sustain the h10 tolerance without overloading the cutting edge.
• Use a sharp center punch and a starting pilot if working on very hard or reflective surfaces to ensure dependable alignment from the first cut.

When you need a single drill that can reliably handle multiple materials, deliver accurate holes quickly, and reach deeper depths without a multi-pass routine, the Dormer Pramet A940 drill is a practical, long-term investment. Its thoughtful geometry and robust construction make it a standout choice for precision drilling in professional manufacturing environments.
