The Dormer Pramet A976 6.70 mm HSS-E High Performance Multi-Application Straight Shank Extra Long Series drill is engineered for serious deep-hole work with reliable precision. Designed to handle a range of materials and provide exceptional reach, this DIN 1869 / 1 drill helps you complete challenging jobs in fewer passes and with cleaner results.

• 130° point for self-centering and reduced push force: The precise tip starts cleanly, minimizes wander, and lowers the effort required to initiate the cut—especially important when time and accuracy matter.
• Bright finish to prevent sticking: The polished cutting edge reduces built-up material on the edge, improving chip evacuation and delivering a smoother hole finish.
• Parabolic flute design for extra-deep holes: Specialized flute geometry enhances chip flow, enabling deep drilling in a single pass without frequent repositions or retracts.
• Premium HSS-E material: High-speed steel enhanced with improved toughness and heat resistance, suitable for drilling steels, aluminum, and stainless steels with dependable performance.
• Extra-long length for extended reach: When space is tight or deep cavities must be accessed, the extended flute and body length deliver the reach you need without sacrificing rigidity.
• Multi-application capability in one drill: Built to handle a variety of common metals encountered in fabrication, automotive, and general engineering tasks, reducing tool changes and setup time.

Ideal use cases: deep-holes in automotive components, aerospace brackets, steel frames, piping assemblies, and other situations where a long reach is essential. It pairs with standard chucks and holders and benefits from proper cutting fluid to maximize life and hole quality across steels, aluminum, and stainless steel.

Compared to shorter, single-purpose drills, the A976 extra-long series delivers deeper holes in fewer passes thanks to its optimized geometry and durable HSS-E core. This translates to faster cycles, less tool swapping, and more consistent hole dimensions in demanding applications.

Practical tips for best results: begin with a light, steady feed to seat the point, then increase speed as the chip flow stabilizes. Use adequate lubrication or coolant for metal drilling, and pause periodically to clear chips on very deep holes. Inspect the cutting edge for wear and re-sharpen when necessary to maintain precision and extend tool life.
