Dormer Pramet A978 7.00 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK EXTRA LONG SERIES (3) DRILL DIN 1869 / 3

Meet the Dormer Pramet A978 7.00 mm HSS-E High-Performance Multi-Application Straight Shank Extra-Long Drill (DIN 1869). This pack of three is built for demanding deep-hole work, delivering reliable, consistent results across a range of materials. When you need reach without sacrificing accuracy, this drill is designed to perform from the first cut to the final depth.

• 130-degree point for self-centering starts and reduced push force, helping you begin holes cleanly and with less effort.
• Bright finish minimizes built-up material on the cutting edge, promoting smoother cutting and easier chip evacuation.
• Parabolic flute design engineered to evacuate chips efficiently, enabling extra-deep holes to be drilled in a single pass without clogging or wandering.
• Premium HSS-E material suitable for drilling a variety of metals, including steel, aluminium, and stainless steel, with improved wear resistance and longer tool life.
• Extra-long length provides extended reach for deep-hole applications and parts with limited access, without compromising rigidity or control.
• Straight shank ensures compatibility with common drill chucks and setups, simplifying tool changes on busy workstations.
• DIN 1869 specification confirms standardized geometry and performance for consistent results across compatible machines and tooling portfolios.
• Pack of 3 lets you keep a steady supply for ongoing projects without reordering mid-task, reducing downtime.

This drill is an ideal choice for machinists, fabricators, and maintenance technicians who tackle deep-hole tasks in steel, stainless steel, and aluminum. Whether you're assembling mechanical components, plumbing through-wall conduits, or creating passage holes in structural parts, the A978’s combination of precision point geometry, aggressive flute design, and extended reach helps you complete jobs faster with fewer passes and less risk of wandering.

Practical tips for best results: match cutting speed to the material, apply light lubrication to reduce heat build-up, and use a firm pecking approach to clear chips when drilling deep holes. Always secure the workpiece and verify the drill’s alignment before starting, and replace worn drills promptly to maintain hole quality and dimensional accuracy.
