Dormer Pramet A977 3/16 Inch HSS-E HIGH PERF MULT-APP STRAIGHT SHANK EXTRA LONG SERIES (2) DRILL DIN 1869 / 2

The Dormer Pramet A977 3/16 Inch HSS-E High Performance Multi-App Straight Shank Drill is engineered for professionals who demand precision, durability, and the versatility to tackle challenging hole depths across multiple materials. Built to perform in everyday workshops and precision machining environments, this drill delivers dependable results from start to finish.

• 130-degree point for confident starts—the angled tip promotes self-centering alignment and reduces the push force required, helping you avoid wandering and achieve clean holes right away.
• Bright finish that minimizes sticking—the smooth, reflective surface reduces adherence of workpiece material to the cutting edge, extending tool life and reducing dwell time between holes.
• Parabolic flute design for deep-hole drilling—optimized chip evacuation and reduced vibration enable you to drill very deep holes in a single pass, improving hole straightness and process efficiency.
• Premium HSS-E material—high-speed steel with enhanced wear resistance supports drilling into a wide range of materials, including steel, aluminum, and stainless steel, while maintaining edge retention across long workpieces.
• Extra-long length for maximum reach—designed for applications requiring deep access, extended reach into fixtures, jigs, or recessed areas without compromising rigidity.
• DIN 1869 / 2 straight shank excellence—compatible with standard drill chucks and holders, ensuring reliable clamping and predictable performance in everyday setups.

Who should consider this drill? machinists, maintenance technicians, fabricators, and DIY enthusiasts tackling deep-hole projects in metalworking, automotive repair, and industrial fabrication. Its combination of self-centering geometry, durable HSS-E construction, and an extra-long reach makes it a standout choice when standard drills fall short for long, precise bores.

Practical usage tips: run at appropriate speeds for the material, apply steady, moderate feed pressure, and use cutting fluid or coolant to cool the edge and improve finish on harder steels. For deep-hole work, rely on the parabolic flute to manage chips effectively and maintain alignment throughout the drilling sequence.
