Engineered for demanding metalworking tasks, the Dormer Pramet A978 8.00 mm HSS-E High-Performance Multi-Application Straight Shank Extra-Long Drill (DIN 1869 / 3) is built to deliver dependable precision and extended reach across a broad range of materials. The extra-long length expands your capability, letting you reach deep into assemblies, molds, or recessed workpieces without compromising rigidity.

• 130-degree point for self-centering — starts holes accurately and reduces the pushing force required, helping prevent wandering in tough materials.
• Bright finish — minimizes material from sticking to the cutting edge, promoting cleaner cuts and longer tool life.
• Parabolic flute design — optimized for deep-hole drilling, enabling efficient chip evacuation and stable penetration in a single pass.
• Premium HSS-E material — cobalt-enhanced high-speed steel that sustains hardness under heat, suitable for drilling steel, aluminium, and stainless steel with reliable performance.
• Extra-long length series — ideal for very deep holes and applications where extended reach is essential, from fabrication and aerospace to automotive repairs.
• Multi-application capability — designed to handle a broad spectrum of metals and non-ferrous materials, reducing tool changes and increasing workflow efficiency.

In real-world use, this drill shines on deep-hole projects, whether you’re threading through stainless steel dashboards, aluminum frames, or thick steel plates with limited access. The combination of a precise 130-degree point and efficient parabolic flutes delivers controlled entry, smooth cutting action, and consistent hole quality—even as workpieces demand prolonged drilling sessions.
