Dormer Pramet A940 7.00 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

A940 7.00 mm HSS-E Long Series Drill is a purpose-built, high-performance tool designed for engineers and machinists who demand reliable, repeatable holes in a variety of materials. This DIN/ANSI straight-shank drill is engineered for deep reach without compromising precision, making it the go-to choice for multi‑purpose drilling tasks where accuracy and productivity matter.

Whether you’re fabricating steel components, aluminum housings, or stainless steel assemblies, this drill handles it with confidence. Its 130° point delivers quick, self-centeringStarts, reducing wandering and minimizing push force as you begin each hole. That means cleaner starts, straighter holes, and less operator fatigue—every time you drill.

Why this A940 drill stands out

• 130° point for true self-centering and easier start-up, especially in hard or tough-to-center materials.
• Bright finish minimizes sticking of workpiece material to the cutting edge, helping chips flush away and maintaining a clean cut.
• Parabolic flute design enables rapid chip evacuation and supports drilling extra-deep holes in a single pass, reducing cycle time and the need for pecking.
• Premium HSS-E (cobalt-based) material delivers excellent wear resistance and performance across a broad material spectrum, including steel, aluminum, and stainless steel.
• Long-series drill with straight shank for compatibility with common toolholding systems and deep-hole applications, all in a single, robust geometry.
• High-performance drilling capability with tight hole quality, enabling H10 tolerance even at elevated speeds and feeds.

The A940 family is built for repeatable results in production lines and on job sites alike. Its multi-application design means you can rely on it for a wide range of drilling tasks without swapping tools, saving time and reducing tool inventory complexity.

Ideal applications and materials

• Steel, including alloys and mild steels, where clean starts and consistent hole size matter.
• Aluminum components where lightness and quick penetration are advantageous.
• Stainless steel workpieces that require reliable edge quality and good wear resistance.
• Long-reach drilling tasks thanks to the long-series geometry and straight shank, which preserves rigidity in deeper holes.

Practical guidance for best results

To maximize performance, match cutting speeds and feeds to the material being drilled and use appropriate cooling or cutting fluid. Secure the workpiece firmly, maintain a steady feed, and avoid excessive lateral force to preserve the drill’s precision and edge life. The A940 7.00 mm drill is designed to deliver consistently high-quality holes at high speeds and feeds, with precise hole size control that helps you hit tight tolerances reliably.

In short, this drill combines a purposeful point geometry, reliable HSS-E construction, and a deep-drilling flute design into a single, versatile tool. If your operation demands accurate, repeatable holes in steel, aluminum, or stainless steel—with extended reach and minimal tool changes—the A940 7.00 mm HSS-E Long Series Drill is the smart, hard-working choice.
