Dormer Pramet A940 12.50 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

The Dormer Pramet A940 12.50 mm HSS-E Long Series Drill is engineered for multi‑application precision and depth, combining a 130° point with a parabolic flute to deliver dependable, high‑quality holes across a range of materials. Its straight shank and DIN/ANSI compatibility make it a reliable workhorse for deep drilling in demanding industrial settings.

• 130° self‑centering point aims for immediate true start and minimizes wandering, reducing the push force required during entry.
• Bright, uncoated finish helps prevent workpiece material from sticking to the cutting edge, improving chip flow and reducing built‑up edge.
• Parabolic flute design enables extra‑deep drilling in a single pass, supporting up to 10×D depth without intermittent pecking in steel, stainless steel and alloys.
• Premium HSS‑E material (cobalt‑based) provides enhanced hot hardness and wear resistance, suitable for drilling a broad spectrum of materials including steel, aluminium and stainless steel.
• Long series, straight shank with DIN/ANSI standards ensures compatibility with a wide array of machines while offering extended reach for deep holes, all while maintaining precise hole quality (H10 tolerance).
• High performance, consistent results at higher speeds and feeds, delivering accurate holes with surface finishes you can trust in production environments.

Designed for professionals who need dependable depth and precision in a single drilling operation, the A940 12.50 mm drill stands out for its combination of self‑centering geometry, deep‑hole capability, and material versatility. Whether you’re machining steel, stainless steel or aluminum components, this drill maintains hole geometry integrity from start to finish, reducing cycle times and improving process consistency.
