The Dormer Pramet A940 6.70 mm HSS‑E High Performance Multi‑Application Straight Shank Long Series Drill (DIN/ANSI) is engineered to elevate everyday metalworking into a precision-focused process. Built for versatility and reliability, this long‑series drill handles a wide range of materials with a single, durable tool that stays consistent from start to finish. Key features that translate to real-world results - 130-degree point for self-centering and reduced push force - Start holes with confidence and minimal wandering, even on tough workpieces. This geometry helps your drill bite cleanly without wobble, leading to smoother entry and less operator effort. - Bright finish to prevent sticking - The polished cutting edge minimizes built‑up edges and chip welding, keeping your hole quality consistent and reducing the risk of workpiece grabbing or irregular diameters. - Parabolic flute design for deep-hole performance - Specialized flute geometry facilitates efficient chip evacuation and stable cutting in long, deep holes, enabling one-pass drilling where other bits would require multiple passes or backing out. - Premium HSS‑E material for multi‑material drilling - cobalt‑enhanced HSS (HSS‑E) delivers superior heat resistance and wear life, making it suitable for steel, aluminum, and stainless steels while maintaining cutting edge integrity. - Long series straight shank for reach and rigidity - A robust straight shank provides dependable compatibility with standard chucks and holders, while the extended length gives you added reach in blind pockets and thick sections without compromising rigidity. - High precision with h10 hole tolerance - Designed to deliver consistently accurate holes at high speeds and feeds, helping you reduce secondary finishing work and ensure reliable assembly fits. Who benefits most - Machine shops and fabrication facilities needing a single drill that can handle steel, aluminum, and stainless without swapping tools. - Automotive, aerospace, and general manufacturing environments where deep, precise holes are frequent and downtime matters. - Advanced DIY enthusiasts tackling demanding projects who value drill life, hole quality, and reduced tooling changes. Practical usage guidance - Pair with appropriate speeds and feeds for the material you’re drilling; prioritize steady feeds and avoid overheating to maximize tool life. - Use moderate lubrication or cutting fluid on tougher materials to reduce friction and extend edge life. - Securely clamp workpieces and align the drill starter to maintain the 130-degree point’s self-centering benefits. - For deep holes, maintain a steady rhythm and consider maintaining coolant flow to sustain hole quality through the full depth. This drill is purpose-built to deliver clean, accurate holes across a spectrum of common metals, reducing tool changes and boosting productivity without compromising precision. Its combination of self-centering point geometry, anti‑glare bright finish, and parabolic flute design sets it apart as a dependable, long‑reach solution for demanding drilling tasks.
