When you need a dependable, high-precision drilling solution for a variety of materials, the Dormer Pramet A940 11.80 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI delivers consistently clean holes with less effort. Built for multi-application use, this drill combines accuracy, speed, and versatility into a single tool you can reach for across steel, aluminum, and stainless steel projects.

Key features that matter in real work

• 130° point for self-centering and reduced push force: The optimized geometry finds the pilot hole quickly and starts cutting with minimal entry pressure, which translates into straighter holes and less operator fatigue.
• Bright finish to minimize binding: The polished surface resists picking and material buildup at the cutting edge, keeping feeds smooth and breakout clean, especially on non-ferrous and soft materials.
• Parabolic flute design for deep-hole capability: The unique flute geometry channels chips efficiently and maintains cutting action, enabling deeper holes in a single pass without retracting. Ideal for pockets, blind holes, or through-holes in thick sections.
• Premium HSS-E material for broad compatibility: Engineered for high heat tolerance and toughness, this drill performs reliably in steel, stainless steel, and aluminum with minimal edge dulling.
• High-performance drilling with tight tolerances: Capable of producing high-quality, accurate holes even at higher speeds and feeds, achieving H10 hole tolerance for critical applications.
• Long series, straight shank, DIN/ANSI compatibility: Designed to fit standard drill chucks and holders, with a straight shank that ensures solid seating and repeatability in CNC and manual machines.

Practical use cases

• Machining automotive chassis, heavy equipment frames, or steel structures where deep, precise holes are required.
• Fabrication and assembly work that involves multi-pass drilling; this drill’s depth and flute geometry reduce cycle times by cutting fewer times through material.
• Projects requiring drilling aluminum components or stainless steel fixtures with clean entry and exit surfaces.

With the Dormer Pramet A940, you’re choosing a trusted, industrial-grade tool designed to minimize downtime and maximize hole quality. The combination of a 130° point, bright finish, parabolic flute, and robust HSS-E substrate makes it a reliable workhorse in any metalshop or production environment.
