Dormer Pramet A940 8.30 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

Meet the Dormer Pramet A940 8.30 mm HSS-E High Performance Multi-Application Straight Shank Long Series Drill. Built for reliability across a wide range of materials, this drill combines precision, depth, and compatibility in a single tool that shops and workshops can depend on for daily drilling tasks.

What makes the A940 stand out

• 130° point for self-centering and lower push force: Start holes with minimal wandering and reduce the effort required to penetrate the workpiece, especially when working with tougher metals.
• Bright finish: A smooth, non-stick cutting edge that minimizes material built-up at the point, delivering cleaner holes and longer tool life.
• Parabolic flute design: Optimized geometry that enables deeper, high-quality holes in a single pass, reducing cycle time and improving productivity on long-hole drilling tasks.
• Premium HSS-E material: High-speed steel with enhanced toughness and wear resistance, ideal for drilling a variety of materials including steel, aluminum, and stainless steel.
• Long series with straight shank (DIN/ANSI compatible): Designed for modern drilling rigs and deep-hole applications, offering rigid performance and broad tool compatibility without complex adapters.
• High performance with tight tolerances: Engineered to produce accurate holes at higher speeds and feeds, delivering H10-level hole tolerance for critical components and assemblies.

Practical use cases

Whether you’re fabricating steel frames, CNC-machining aluminum components, or tackling stainless steel housings, the Dormer Pramet A940 drill provides dependable results. Its deep-hole capability and sturdy straight-shank design make it a versatile choice for multi-application drilling in workshops, maintenance shops, and job sites that demand consistent hole quality across materials.

Why it matters for your workflow

In production environments where cycle time and precision matter, the A940 reduces tool changes and rework. The self-centering point minimizes pilot preparation, the parabolic flute sustains aggressive feeds into thicker sections, and the bright finish curbs built-up edge, all helping you hit target tolerances without sacrificing speed.

Tips for best results

• Match speeds and feeds to the material: higher speeds for aluminum, balanced feeds for steel and stainless to maintain stable cutting conditions.
• Use appropriate cutting fluid or coolant to extend tool life and improve surface finish on harder metals.
• Start with a light pilot hole if accuracy is critical, then proceed with the A940 for a clean final hole.
• Ensure proper workholding to prevent deflection—especially important with long-series drills and deeper holes.

Investing in the Dormer Pramet A940 8.30 mm HSS-E High Performance Multi-Application Straight Shank Long Series Drill means choosing a tool built to handle diverse materials, deliver precise results, and endure demanding drilling cycles with consistent performance.
