Dormer Pramet A976 3.10 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK EXTRA LONG SERIES (1) DRILL DIN 1869 / 1

Meet the Dormer Pramet A976 3.10 mm HSS-E High Performance Multi-Application Straight Shank Extra Long Drill (DIN 1869 / 1) — a precision twist drill engineered for deep, consistent holes across a range of materials.

What makes this drill stand out

• 130-degree point for precise self-centering and reduced push force, ensuring clean starts and minimal wandering even in challenging materials.
• Bright finish lowers friction and prevents workpiece material from sticking to the cutting edge, promoting smoother chip flow and less built-up edge.
• Parabolic flute design tailored for drilling extra-deep holes in a single pass, cutting through long depths with improved chip evacuation and hole straightness.
• Premium HSS-E material offers enhanced red hardness and wear resistance, making it suitable for drilling steel, stainless steel, and aluminium with reliable longevity.
• Extra-long length delivers extended reach for deep cavities, blind holes, or hard-to-access workpieces without compromising rigidity or precision.
• Straight shank compatibility with a wide range of collets and toolholding systems for quick, stable tool changes.

This multi-application drill is ideal for machinists, fabricators, and workshop technicians who need dependable performance across materials and depths—delivering consistent hole quality from the first pass to the final depth.

Why this drill matters in your workflow The combination of A976 geometry, HSS-E composition, and parabolic flute translates to longer uninterrupted drilling cycles, improved hole concentricity, and reduced tool wear compared to standard drills when tackling deep-hole tasks.

Practical usage tips

• Match cutting speed and feed to material: steel and stainless steel benefit from conservative speeds with steady feeds; aluminium tolerates higher feeds at moderate speeds for quicker hole formation.
• Maintain steady, minimal runout with a rigid workholding setup to preserve hole accuracy during long-reach drilling.
• Use appropriate coolant or cutting oil to maximize tool life and surface finish in tougher materials.
