Dormer Pramet A940 3/16 Inch HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

Meet the Dormer Pramet A940 3/16 Inch HSS-E High Performance Multi-Application Straight Shank Long Series Drill DIN/ANSI. Engineered for professional metalworking, this drill bit combines toughness, precision, and versatility into a single tool that handles multiple materials with consistent, high-quality results.

• 130-degree point for effortless starting: The geometry centers itself as soon as you touch the workpiece, minimizing walk and reducing the push force required to begin cutting. That means smoother starts and less hand-fatigue in challenging setups.
• Bright finish to resist material adhesion: The polished surface reduces built-up edge and sticking, helping maintain a clean cut and predictable hole dimensions over longer runs.
• Parabolic flute design for deep-hole drilling: This specialized flute shape evacuates chips efficiently, enabling extra deep holes in a single pass and improving hole quality in blind or through holes alike.
• Premium HSS-E material: High-speed steel with cobalt-enhanced properties delivers stable performance across a range of metals, including steel, aluminum, and stainless steel, while retaining strength at higher speeds.
• High-performance drilling with tight tolerances: Capable of maintaining accuracy at high speeds and feeds, achieving hole tolerances around H10 for reliable, repeatable results in demanding applications.
• Long-series, straight-shank design: The DIN/ANSI straight shank fits a wide array of existing tool holders, consoles, and chucks, while the extended length provides reach for deeper pockets and challenging workpieces.

Ideal for machine shops, fabrication floors, and maintenance environments, the A940 is a true multi-application drill that reduces tool inventory without compromising hole quality. Whether you’re drilling into mild steel, aluminum components, or stainless parts, this drill keeps its edge and delivers clean, accurate holes time after time.

Practical guidance for optimal results: choose appropriate cutting speeds for the material type, maintain steady feeds, apply light lubrication where recommended, and pause to clear chips when drilling deeper holes to prevent sticking or binding. Trust the A940 to handle mixed-material workpackages with one trustworthy tool.
