Engineered for precision and longevity, the Dormer Pramet A940 15.00 mm HSS-E High Performance Multi-App Straight Shank Long Series Drill is built to tackle demanding metalworking tasks across materials. With a robust straight shank compatible with DIN/ANSI tooling standards, this drill delivers consistent hole quality in a wide range of applications—from quick pilot holes to deeper drilling jobs in production environments.

• 130-degree point for self-centering and lower thrust: The optimized point geometry reduces pushing force and helps the drill start cleanly, minimizing wander and ensuring accurate hole initiation even in tougher workpieces.
• Bright finish to reduce material sticking: The polished cutting edge resists built-up edge, promoting smoother penetration and cleaner hole diameters across a variety of metals.
• Parabolic flute design for deep holes in one pass: The distinctive flute geometry channels chips efficiently, enabling long, through-holes without frequent retractions or pecking cycles.
• Premium HSS-E material: Enhanced toughness and wear resistance make this drill suitable for drilling steel, aluminium, and stainless steel, delivering dependable performance in diverse work environments.
• Long series with straight shank: Optimized for rigidity and compatibility with a broad spectrum of drill chucks and holders, ensuring stable operation at high speeds.
• High-speed and high-feed capability with h10 hole tolerance: Designed to maintain accuracy at elevated speeds and feeds, producing precise holes that meet demanding tolerance requirements.

This drill is ideal for engineers and shop floors tackling multi-material projects, manufacturing runs, and maintenance tasks where a single drill can deliver reliable performance across different metals. The A940's combination of 15.00 mm diameter, HSS-E composition, and long, straight-shank design provides a robust, versatile solution for drilling deep holes with minimal setup changes, reducing downtime and increasing throughput.

Tips for optimal results: pair the drill with proper cooling/lubrication, set speeds and feeds according to material and machine capabilities, and use a light, consistent pecking cycle when penetrating thicker sections to manage heat and evacuate chips effectively.
