Dormer Pramet A976 2.30 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK EXTRA LONG SERIES (1) DRILL DIN 1869 / 1

Engineered for deep-hole precision, the Dormer Pramet A976 2.30 mm HSS‑E High Performance Multipurpose Straight Shank Extra Long Drill is purpose-built for reach without sacrificing accuracy. Designed to DIN 1869/1 standards, this 2.30 mm drill combines a robust HSS‑E (cobalt-based) composition with a bright finish and a dedicated straight shank to deliver consistent performance across a range of materials—from steel to aluminium and stainless steel.

• 130° self-centering point helps starts cleanly and reduces the push force required to begin cutting, resulting in steadier entry and tighter hole tolerances.
• Bright finish minimizes built-up edge by preventing workpiece material from sticking to the cutting edge, aiding smoother chip flow and reducing binding, especially in harder metals.
• Parabolic flute design is optimized for drilling extra-deep holes in a single pass, reducing the need to retract and re‑peck the hole and improving overall drilling efficiency.
• Premium HSS‑E material (cobalt-based steel) offers enhanced red hardness and wear resistance, making it suitable for a variety of metals including steel, aluminium and stainless steel.
• Extra-long length series delivers increased reach for long workpieces and deep-hole applications, without compromising rigidity or cutting performance when used with a straight shank setup.

What this means in practical terms is a drill that can tackle long through-holes, deep cavity access, and tall workpieces with fewer tool changes. The A976 family is ideal for machinists, fabricators, and hobbyists who routinely drill deep into metals and require a reliable, repeatable solution that stays sharp through multiple passes. Its straight shank and DIN standard formulation ensure compatibility with common drilling chucks and setups, making it a straightforward upgrade for deep-hole projects.

Use cases include precision through-holes in long steel assemblies, reinforcement plates, or components where access is limited and hole depth is a critical factor. When drilling softer aluminium or tougher stainless steel, the HSS‑E composition, combined with the 130° point and parabolic flute, helps maintain control, reduce wandering, and extend tool life compared with standard-length drills.

Tips for best results: start with a light, even feed to establish the hole, maintain appropriate speeds for the material, and use steady lubrication to prevent chip packing in deep holes. Pair this drill with a rigid holder and a well‑tuned drill press or milling setup to maximize the benefit of its long reach and parabolic flute geometry.
