Dormer Pramet A976 2.70 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK EXTRA LONG SERIES (1) DRILL DIN 1869 / 1

Engineered for precision deep-hole drilling, the Dormer Pramet A976 2.70 mm HSS-E High Performance Multi-Application Straight Shank Extra Long Series drill is built to reach where conventional drills can’t. With a robust HSS-E core and an extended flute geometry, this drill delivers consistent accuracy and reliability across a range of materials, making it a must-have for long-bore applications in fabrication, automotive, and aerospace settings.

• 130-degree point: promotes self-centering from the moment the tip touches the workpiece and reduces the push force required, minimizing wandering and ensuring starting accuracy in challenging materials.
• Bright finish: helps prevent workpiece material from sticking to the cutting edge, supporting smoother cuts and cleaner holes, even in tough alloys.
• Parabolic flute design: optimized for deep-hole drilling, this flute geometry efficiently evacuates chips in a single pass, reducing heat build-up and the risk of clogging on long bores.
• Premium HSS-E material: enhanced wear resistance and toughness, suitable for drilling steel, aluminium, and stainless steel without sacrificing performance or edge life.
• Extra-long length series (DIN 1869 / 1): designed for applications requiring extended reach, enabling deep holes and through-holes in workpieces with limited access or thick sections.

Who needs this drill? Professionals tackling long-bore tasks such as engine blocks, thick plates, or intricate mold components where reach and precision matter. It’s ideal for shops that demand dependable performance from a single tool across multiple materials, reducing the need to switch between specialized drills.

Practical usage notes to maximize life and results:

• Match cutting parameters to material: moderate rpm with steady, controlled feed for steel; higher speeds and careful feed for aluminum to avoid built-up edges.
• Use appropriate cutting fluid or light oil to cool the tip and extend edge life during deep-hole drilling.
• Secure the workpiece and use a stable drilling setup to mitigate deflection given the drill’s extra length.
• Start with a small pilot hole if precision is critical, then advance to the 2.70 mm drill for a clean, accurate bore.
