Meet the Dormer Pramet A978 6.00 mm HSS-E High-Performance Multi-Application Straight Shank Extra Long Series drill (DIN 1869 / 3) — a precision-driven tool built for demanding metalworking tasks where depth and accuracy matter. This drill is designed to tackle deep through-holes and hard-to-reach workpieces with confidence and consistency.
- 130° point for self-centering and smoother starts: The geometry guides the drill into the material, reducing wandering and the pushing sensation often felt at the outset of a hole. Expect cleaner starts and more controlled drilling, even in challenging workpieces.
- Bright finish minimizes sticking: The polished surface helps reduce friction between the cutting edge and workpiece material, promoting smoother chip flow and cleaner hole entry. It also aids in deburring and finish consistency across runs.
- Special parabolic flute design for deep holes: Engineered to evacuate chips efficiently, the parabolic flutes support a single-pass approach to deep holes, reducing dwell time and the need for frequent pecking or tool changes.
- Premium HSS-E material for versatility and longevity: Built to handle a wide range of metals — from steel and aluminum to stainless steel — delivering reliable performance and extended tool life under demanding conditions.
- Extra-long length for exceptional reach: When a standard drill can’t access the depth you need, this extra-long series delivers the reach required for deep pocket drilling, long through-holes, and recessed cavities without compromising rigidity.
- Straight shank and DIN 1869 / 3 compliance: The straight shank design ensures compatibility with common chucks and holders, while DIN 1869 / 3 standardization guarantees interchangeability and predictable performance across compatible machines.
- Multi-application versatility: A single drill that performs across multiple metals and thicknesses, simplifying your toolkit and reducing the need to switch tools mid-project.
Ideal for machinists, fabricators, maintenance technicians, and toolmakers, the Dormer Pramet A978 6.00 mm drill empowers you to complete precision deep-hole work with fewer tools, less rework, and a more consistent hole quality. When depth and reach are non-negotiable, rely on this high-performance HSS-E drill to deliver accurate starts, smooth chip evacuation, and dependable long-life performance in metalworking environments.
