When you need a drill that combines deep reach with reliable, multi-material performance, the Dormer Pramet A978 1/4 Inch HSS-E High Performance Multi-Application Drill is the tool you reach for. This 3-piece extra-long drill set is built around a straight shank for secure, precise chuck engagement and consistent hole quality, even in thick or challenging workpieces.

• 130° point facilitates self-centering and reduces the push force required, helping you start holes cleanly and reduce wandering.
• Bright, anti-sticking finish minimizes material adhesion at the cutting edge, keeping feed forces predictable and chips moving freely.
• Parabolic flute design enables efficient chip evacuation and supports DRILLs that reach deep into the workpiece in a single pass.
• Premium HSS-E material delivers high wear resistance and toughness, suitable for drilling a wide range of materials including steel, aluminum, and stainless steel.
• Extra-long length provides extended reach for deep holes, recessed cavities, and assemblies where standard-length drills can’t reach the target depth.
• DIN 1869 compatibility ensures dependable performance with standard drilling setups and tooling systems.

This drill is ideal for machinists, engineers, maintenance technicians, and serious hobbyists who tackle thick plates, long bores, or assemblies where access is limited. Use it for drilling through automotive housings, hydraulic blocks, machinery frames, or long through-holes where precision and consistency matter. The combination of a 1/4 inch diameter, HSS-E composition, and an extra-long geometry means fewer re-drills, smoother chip clearance, and more consistent hole sizes down the run of the workpiece.

Designed to outperform everyday drill bits in demanding environments, the Dormer Pramet A978 line stands up to repeated use across steel, stainless steel, and aluminum without sacrificing precision. If you’re aiming for accuracy, efficiency, and deeper holes in a single pass, this is the drill you’ll reach for first.
