Meet the Dormer Pramet A940 5.10 mm HSS-E High Performance Multi-Application Drill — a straight shank, long-series drill designed to deliver clean, accurate holes across a wide range of materials. Built for precision and resilience, it’s the go-to choice when you need dependable performance in everyday metalworking tasks.
Why this drill stands out
- 130-degree point: The specialized point geometry promotes self-centering upon entry and significantly reduces the push force required, helping you start holes with confidence and reduce wandering.
- Bright finish: The bright, clean cutting edge minimizes material adhesion and built-up edge, producing smoother cuts and reducing dwell time for deburring or rework.
- Parabolic flute design: This unique flute geometry is optimized for drilling deeper holes in a single pass, improving chip evacuation and reducing the need for pecking or multiple passes.
- Premium HSS-E material: High-speed steel with enhanced alloying delivers excellent wear resistance and toughness, making it suitable for drilling steel, aluminum, and stainless steel with consistent results.
- Long, straight shank (DIN/ANSI): Designed for compatibility with a variety of power tools and collet systems, the extended reach enables deeper hole drilling without compromising stability.
- High-performance hole quality: Engineered to produce precise, round holes at higher speeds and feeds, achieving h10 hole tolerance for dependable fits in assemblies.
Ideal use cases
Perfect for workshops and production floors where you encounter mixed-material drilling. Use this drill for:
- General-purpose drilling in carbon steel, stainless steel, and aluminum components
- Deep-hole tasks where a single-pass approach saves time and enhances productivity
- Applications requiring tight tolerances and reliable hole quality at elevated speeds
- DYI and professional machining environments where a versatile, long-reach drill is valued
With the Dormer Pramet A940, you’re choosing a tool that combines precise geometry, durable construction, and practical design features to help you finish jobs faster and with fewer reworks. It’s a multi-application workhorse built to handle real-world machining challenges with confidence.
