Discover precision and versatility with the Dormer Pramet A940 17.00 mm HSS-E High Performance Multi‑App Straight Shank Long Series Drill DIN/ANSI. Designed for demanding work in metal, this drill blends speed, depth, and control to deliver consistently clean, accurate holes across a range of materials.

Key features that drive real results

• 130° point for effortless self‑centering and reduced push force, helping operators start holes with minimal wandering and improved accuracy.
• Bright finish minimizes material buildup on the cutting edge, reducing friction and promoting smoother chip evacuation for longer tool life.
• Parabolic flute design enables deep holes to be drilled in a single pass, increasing throughput and reducing tool changes in production environments.
• Premium HSS‑E material awarded for its toughness and wear resistance, suitable for drilling steel, aluminum, and stainless steel without compromising hole quality.
• H10 hole tolerance delivers high‑precision results at compatible speeds and feeds, making it a reliable choice for precision applications and assemblies.
• Long series, straight shank construction provides extended reach and dependable compatibility with a broad range of toolholding systems (chucks and collets), ideal for deeper hole drilling in typical DIN/ANSI setups.

Why this drill stands out in real-world fabrication

In workshops that demand repeatable hole quality, the A940 delivers standout performance. The 130° point reduces the initial thrust required to begin cutting, which translates to less tool wear and more consistent hole initiation—even on tougher materials. The parabolic flute geometry isn’t just about depth; it supports efficient chip flow, minimizes clogging, and helps sustain high feed rates without sacrificing accuracy.

Materials, applications, and scenarios

Whether you’re working with mild or stainless steel, aluminum profiles, or composite components, this drill maintains stable performance at elevated speeds. It’s particularly well suited for manufacturing setups where long, straight holes are common—think through‑hole drilling in frame components, electrical enclosures, or machinery housings. The multi‑application design means you can rely on a single tool for drills across multiple tasks, reducing tool inventory while maintaining precision standards.

Practical usage tips

• Pair with appropriate coolant or lubrication to maximize edge life and chip evacuation, especially in stainless steel or high‑hardness alloys.
• Use steady feeds to match the parabolic flute’s designed chip load; abrupt feeds can compromise hole roundness at depth.
• Ensure proper workholding and alignment to take full advantage of the straight shank’s reliable runout characteristics in DIN/ANSI configurations.
• Inspect drill wear regularly; a slight dulling can cause increased runout and reduced hole tolerance (H10) quality.

Size and compatibility: 17.00 mm diameter, HSS‑E construction, long series with straight shank designed for compatibility with standard toolholding systems and DIN/ANSI tooling setups.
