Dormer Pramet A940 2.00 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

Meet the Dormer Pramet A940 2.00 mm HSS-E High Performance Multi-Application Drill, a precision tool built for reliability across a range of materials. Its design is tailored for accuracy, longevity, and deep-hole capability in a single pass, making it a standout choice for meticulous workshop environments and production floors alike.

• 130-degree point for effortless self-centering and reduced push force, helping you start holes cleanly without wandering or skate.
• Bright finish engineered to minimize material adhesion on the cutting edge, promoting smoother starts and extended edge life.
• Special parabolic flute design enables deep-hole drilling in one pass, improving throughput and reducing the need for secondary reaming passes.
• Premium HSS-E material delivers robust performance across a variety of workpieces, including steel, aluminum, and stainless steel, with durable edge retention.
• High-performance drilling capable of maintaining quality at higher speeds and feeds, producing precise holes with H10 tolerance for reliable interchangeability in assemblies.
• Long series, straight shank provides extended reach in DIN/ANSI standards, accommodating deeper cavities and multi-depth drilling without changing tooling setups.

Ideal for general engineering, automotive fabrication, and precision metalworking where hole quality and consistency matter. In steel and stainless steel, this drill maintains concentricity and clean edge geometry even at elevated speeds, while in aluminum it resists grabbing and chatter, delivering smooth, chip-free cuts. The A940 is a practical choice for multi-material shops that demand one drill to handle diverse tasks—from pilot holes to final engineering holes with tight tolerances.

Compared to conventional high-speed drills, the A940’s HSS‑E composition and optimized geometry extend tool life and reduce downtime, enabling you to push for higher productivity without sacrificing accuracy. Its design supports reliable chip evacuation and stable performance through long drilling cycles, making it a dependable workhorse for repetitive manufacturing or rapid prototyping environments.

Practical tips for best results
- Use appropriate speeds and feeds for the material being drilled; start with conservative values and increase as cutting conditions permit.
- Apply light, continuous lubrication to minimize built-up edge on steel and stainless steel.
- Secure the workpiece firmly and use backing material when drilling blind holes to prevent burrs and deflection.
- For deep holes, ensure adequate chip clearance or use peck drilling techniques to maintain cutting efficiency.
