Dormer Pramet A940 3/64 Inch HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

Unlock precision drilling with the Dormer Pramet A940 3/64 Inch HSS-E High Performance Multi-Application Straight Shank Long Series Drill (DIN/ANSI). Built for professional metalworking, this drill combines aggressive geometry with a refined finish to deliver clean holes fast and consistently.

What makes this drill stand out

• 130° point geometry — self-centering and reduces push force, helping you start holes with minimal wandering and less operator effort.
• Bright finish — a smooth, non-stick cutting edge that minimizes built-up material on the edge for smoother holes and reduced chatter.
• Parabolic flute design — engineered for deep-hole drilling in a single pass, improving chip evacuation and reducing clogging when drilling long sections.
• Premium HSS‑E material — a tough, wear-resistant steel that performs well across a range of common metals including steel, aluminum, and stainless steel.
• Long series, straight shank — designed for versatile use in a wide range of machines, with consistent runout and secure tool retention.
• DIN/ANSI compatibility — certified to industry standards, ensuring interchangeability with a broad range of drill chucks and holders.
• High performance with H10 tolerance — capable of producing high-quality, accurate holes even at higher speeds and feeds.

Ideal use cases

Perfect for fabrication shops, maintenance, and engineering labs needing reliable small-diameter drilling in metals. Use it for:

• Precision pilot holes in steel and stainless steel without wandering.
• Through-holes in aluminum panels, dashboards, or housings where finish matters.
• Multi-pass drilling where a long, straight flute helps maintain speed without overheating.

Tips for best results

- Match cutting speed to the material and hole depth; for deeper holes, rely on chip evacuation and consider lubrication to prolong edge life.
- Keep the drill sharp and clear debris from the flutes to maintain hole quality.
- Use proper clamping to minimize runout and ensure safe operation.

What you get

A single, high-performance drill designed for multi-material drilling with a long service life and predictable results. The 3/64" diameter is ideal for small-diameter workpieces, precise features, and delicate assemblies where hole tolerances and edge quality matter.
