Dormer Pramet A976 5.00 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK EXTRA LONG SERIES (1) DRILL DIN 1869 / 1

Dormer Pramet A976 5.00 mm HSS-E High Performance Multi-Application Straight Shank Extra Long Series drill (DIN 1869 / 1) is designed for serious deep-hole work where reach matters as much as precision. Built to handle a variety of materials with reliability, this drill pairs a thoughtfully engineered geometry with a robust cobalt-enhanced steel to deliver consistent results in demanding environments.

Key features that matter on the shop floor

• 130-degree point for confident self-centering and a noticeably lower push force, helping you start holes cleanly even in tough workpieces.
• Bright finish reduces material sticking to the cutting edge, minimizing built-up edge and improving hole quality in a range of metals.
• Parabolic flute design specialized for extra-deep holes, enabling deep drilling in a single pass without constant reorientation or multiple passes.
• Premium HSS-E material capable of drilling steel, aluminum, and stainless steel with dependable performance and longer tool life under typical production conditions.
• Extra-long length series engineered for applications calling for increased reach—ideal when access is limited or holes must be drilled deep within assemblies.
• DIN 1869 / 1 straight shank ensures compatibility with a wide range of collets and chucks, providing stable guidance and consistent centering.

Ideal applications and use cases

• Deep-hole drilling in structural steel, machinery frames, and automotive components where standard-length drills fall short.
• Through-holes and blind holes that require a long reach without sacrificing accuracy or drill sturdiness.
• Workpieces with tight tolerances and limited access—perfect for setups where clamping space or fixture geometry restricts tool length.
• Prototyping and production environments where one drill can handle multiple materials, reducing tool changes and machining time.

Why this drill stands out

• Unlike standard-length drills, the A976’s extra length combined with a self-centering 130-degree point minimizes wandering, improves hole start quality, and reduces the need for rework.
• The parabolic flute design ensures efficient chip evacuation in deep holes, lowering heat and prolonging tool life while preserving hole geometry.
• HSS-E construction delivers a balance of hardness and toughness, enabling reliable drilling across a spectrum of common metals without frequent tool replacement.

Practical tips for best results

• Use appropriate cutting speeds and feeds for the material at hand; stainless steels benefit from moderated speeds and proper lubrication to minimize workpiece work hardening.
• Secure the workpiece firmly and maintain proper alignment to maximize the benefits of the 130-degree point and reduce deflection.
• Choose a compatible chuck or collet that accommodates the straight shank for stable, straight drilling; ensure the drill is mounted true to the work surface.
• Periodically inspect for wear and clear chips to avoid workpiece recutting, especially in deep-hole scenarios where heat can accumulate.
