The Dormer Pramet A940 14.00 mm HSS‑E High Performance Multi‑App Straight Shank Long Series Drill is engineered for precision, versatility, and long-term reliability in metalworking projects. Designed to excel across multiple materials and drilling scenarios, this drill delivers consistent hole quality from start to finish, even at higher speeds and feeds. Key features that set the A940 apart
- 130-degree point: A true self‑centering entry that reduces start‑up push, minimizes wandering, and yields cleaner holes with less guidance effort.
- Bright finish: A smooth, reflective surface that helps prevent built‑up material from sticking to the cutting edge, promoting steadier cuts and easier chip evacuation.
- Parabolic flute design: Optimized for deep-hole drilling, the flute geometry efficiently evacuates chips, enabling deeper holes in a single pass and reducing drill dwell time.
- Premium HSS‑E material: High-speed steel with enhanced alloying for superior toughness and wear resistance, suitable for drilling steel, stainless steel, and aluminum with reliable tool life.
- High‑performance drilling: Tuned for quality and accuracy at higher speeds and feeds, producing round, true holes with tight tolerances (H10) for dependable assembly fit.
- Long series, straight shank, DIN/ANSI compatibility: A robust, straight shank that fits a wide range of chucks and holders, designed to meet common DIN/ANSI standards for seamless integration into professional setups. Who is this drill ideal for
- Machinists and plant floor technicians who need a single drill capable of handling multiple materials without swapping tools.
- Shops that require deep-hole capability in a single pass, reducing cycle times and increasing throughput.
- Engineers and fabricators looking for consistent hole quality and repeatable results in steel, stainless steel, and aluminum components. Why this drill matters in practice
- Deep-hole reliability: The parabolic flute geometry isn’t just about deeper holes—it’s about maintaining consistent chip clearance and cutting efficiency as hole length increases.
- Reduced tool wear: The 130-degree point and premium HSS‑E composition work together to minimize edge wear and prolong usable life between sharpener cycles.
- Precision you can trust: With H10 hole tolerance, you’ll see cleaner finishes and tighter assembly tolerances, cutting rework and improving overall part quality. Practical use scenarios
- Automotive components: drilling through zinc-coated or stainless parts with clean, straight holes that align perfectly in assemblies.
- Hydraulic and pneumatic manifolds: deep, accurate through-holes in aluminum or stainless manifolds where chip control and hole quality matter.
- General fabrication: multi-material projects requiring a dependable drill that performs consistently across steel, aluminum, and stainless workpieces. For best results
- Secure clamping is essential to maximize stability, especially when drilling long or deep holes.
- Choose appropriate speeds and feeds according to the material family; use light cooling or cutting fluid for steels to extend edge life.
- Start with a center or spot drill to establish a precise entry point, then proceed with the A940 for a clean, true hole. The Dormer Pramet brand is trusted by professionals worldwide for durable, precision tooling. The A940 14.00 mm HSS‑E drill embodies that commitment, delivering dependable performance in a compact, DIN/ANSI‑compatible package.
