Dormer Pramet A940 3.20 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

The Dormer Pramet A940 3.20 mm HSS-E High Perf Multi-App Straight Shank Long Series Drill DIN/ANSI is a precision micro-drill built to deliver clean starts, tight tolerances, and dependable performance across a range of materials. Designed for reliability in demanding fabrication, this drill combines advanced geometry with robust construction to elevate everyday milling tasks into repeatable, high-quality holes.

• 130° point: self-centering on contact and reduced push force help you begin precision holes more reliably, even on challenging workpieces.
• Bright finish: minimizes material adhesion to the cutting edge, promoting smoother cutting action and cleaner chip evacuation.
• Parabolic flute design: optimized geometry enables drilling extra deep holes in a single pass, improving efficiency and reducing cycle time.
• Premium HSS-E material: durable across a broad material range, including steel, aluminium, and stainless steel, with improved wear resistance for repetitive use.
• High performance at various speeds and feeds: engineered to produce consistently high-quality, accurate holes, maintaining H10 hole tolerance even under demanding conditions.
• DIN/ANSI straight shank, long series: proven compatibility with standard holders and tool setups, offering dependable rigidity and reach for longer drilling tasks.

This drill is ideal for professional machinists, job shops, and maintenance teams who require a single tool capable of delivering precise holes in multiple materials without swapping setups. The A940 3.20 mm stands out through its combination of precise point geometry, efficient flute design, and a robust HSS-E construction that translates into fewer retries and tighter tolerances compared with generic micro-drills.

Use cases include drilling small-diameter holes in steel, aluminium parts, and stainless components where accuracy and surface finish matter. Its long-series design and straight shank improve stability in deeper holes and challenging workpieces, making it a versatile choice for electronics enclosures, hardware assemblies, and intricate mechanical assemblies.
