Dormer Pramet A976 2.10 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK EXTRA LONG SERIES (1) DRILL DIN 1869 / 1

The Dormer Pramet A976 2.10 mm HSS-E drill is a precision-focused micro-drilling solution built for real-world metalworking challenges. Designed for reliability in difficult materials and tight spaces, this extra-long, straight-shank drill blends advanced geometry with cobalt-enriched high-speed steel to deliver clean, repeatable holes with fewer passes.

Why this drill stands out

• 130-degree point for self-centering — the sharp, precise tip reduces wandering and lowers the push force needed to start a hole, giving you first-pass accuracy even in challenging workpieces.
• Bright finish for reduced sticking — a slick cutting edge surface minimizes built-up edge and workpiece material adhesion, resulting in smoother drilling and less chatter.
• Parabolic flute design — engineered to evacuate chips efficiently, this flute profile enables you to drill deep holes in a single pass without clogging, increasing throughput and reducing tool wear.
• Premium HSS-E material — cobalt-enhanced high-speed steel provides improved red hardness and wear resistance, making it suitable for drilling a range of metals, including steel, aluminum, and stainless steel.
• Extra-long length, straight shank — optimized for reach where standard bits can’t, ideal for blind holes, internal pockets, and applications requiring extended reach while maintaining secure chuck grip.
• DIN 1869 / 1 specification — built to the DIN standard for small-diameter drills, ensuring compatibility with professional drilling setups and repeatable interchangeability.
• Diameter 2.10 mm in a single-drill package, designed for precision work where tight tolerances and clean hole finishes matter.

Ideal applications

• Micro-drilling in steel, stainless steel, and aluminum components where space is limited and hole depth is substantial.
• Electronics enclosures, instrumentation housings, and precision mechanical assemblies needing accurate, small-diameter through-holes or deep blind holes.
• Automotive and aerospace prototyping where tight tolerances and robust drill life are essential for small fastener holes or cooling channels.
• Tooling and fixture work where consistent hole quality reduces post-processing and assembly time.

Performance tips for best results

• Match speeds and feeds to the material and depth. For softer metals like aluminum, run at moderate speeds with steady feeds; for steel and stainless, use conservative feeds to manage heat and extend edge life.
• Use ample lubrication or coolant on tougher materials to reduce friction, minimize built-up edges, and prolong tool life.
• Keep workpieces securely clamped to prevent vibration, which can affect hole accuracy at small diameters and long reach.
• Start with a light touch to establish a clean pilot, then steadily increase feed to maintain a smooth cutting action through deep holes.
• Inspect the bit for signs of wear or micro-chipping after long drilling sessions; the parabolic flute design helps manage chip evacuation, but extreme depths or hard materials will still benefit from periodic inspection.

Whether you’re crafting precise micro-holes in thin plates or drilling deep, hard-to-reach bores in assemblies, the Dormer Pramet A976 2.10 mm HSS-E drill is built to deliver dependable accuracy and enduring performance. This single high-precision drill combines specialized geometry with robust materials to help you achieve cleaner finishes, fewer passes, and faster production cycles in demanding metalworking environments.
