Meet the Dormer Pramet A978 9.00 mm HSS-E High Performance Multi-Application Extra Long Straight Shank Drill (DIN 1869) — a precision tool built for depth, reach, and reliability. This three-pack is crafted for professionals who tackle demanding drilling tasks across a range of materials without swapping systems.

Why this drill stands out

• 130° point geometry delivers quick self-centering starts, minimizes wandering, and lowers the required push force — you get cleaner holes with less effort.
• Bright finish reduces material build-up on the cutting edge, promoting smoother entry and reducing heat which can dull the edge over time.
• Parabolic flute design optimizes chip evacuation in deep holes, enabling efficient drilling in a single pass and helping prevent clogging in long workpieces.
• Premium HSS-E substrate provides superior toughness and wear resistance, suitable for drilling steel, aluminium, and stainless steel with consistent performance.
• Extra long length delivers extended reach for deep cavities, blind holes, and applications where standard drills can’t reach—without compromising rigidity.
• Straight shank offers broad compatibility with a wide range of chucks and holders, ensuring secure alignment in busy workshop environments.
• DIN 1869 specification ensures reliable interchangeability in standard drill seats and equipment, making replacements straightforward in established workflow.

Ideal for demanding applications

• Deep-hole drilling in automotive, aerospace, and general maintenance projects where access is limited.
• Fabrication tasks that require drilling through steel frames, aluminium profiles, or stainless fittings with minimal deflection.
• Workshop setups that benefit from a consistent supply of three high-performance drills to keep production lines moving.

Practical tips for best results

• Use appropriate cutting speeds and lubrication to maximize tool life with HSS-E drills when drilling stainless steel or coated materials.
• Secure the workpiece firmly and consider pilot holes for especially hard or brittle materials to guide the 130° point accurately.
• For deepest holes, rely on the extended reach of this extra-long series, but maintain steady feeds to preserve flute integrity and edge life.

Built for professionals who value precision, durability, and versatility in one trusted drill, the Dormer Pramet A978 9.00 mm HSS-E High Performance Multi-Application Extra Long Straight Shank Drill is ready to tackle challenging holes with confidence in steel, aluminium, and stainless steel alike.
