When the job demands deep, precise holes with dependable performance, the Dormer Pramet A976 5.70 mm HSS-E High Performance Multi-Application Straight Shank Extra Long Drill DIN 1869 stands out. Built for versatility and endurance, this drill bit is a go-to choice for demanding fabrication and maintenance tasks where reach matters as much as accuracy.

• Diameter and standard: 5.70 mm drill bit engineered to DIN 1869, ensuring seamless compatibility with common drill chucks and holders.
• 130° point for self-centering: Optimized tip geometry centers itself quickly, reduces wandering, and lowers the push force needed to start a hole.
• Bright finish: A smooth cutting edge minimizes material adhesion and built-up edge, yielding cleaner holes and less post-processing.
• Parabolic flute design: Specially contoured flutes optimize chip evacuation, enabling deep-hole drilling in a single pass and maintaining steady progress.
• Premium HSS‑E material: High-performance steel with enhanced heat resistance delivers longer tool life across steel, stainless steel, and aluminum.
• Extra-long length: Designed for very deep holes and applications requiring extended reach without compromising rigidity.
• Straight shank: Broad compatibility with a wide range of drill chucks, collets, and holders for reliable performance.
• Multi-application capability: A true all-rounder that handles a variety of metals, making it ideal for mixed-material projects and production environments.

Use cases span engineering workshops, automotive fabrication, machine maintenance, and aerospace component production—any scenario that needs clean, deep holes with minimal tool changes and consistent results.

Why this drill matters: deeper holes in a single pass reduce cycle times, minimize tool wear from re-drilling, and improve precision in blind-hole work. The A976 combines targeted geometry with robust materials to deliver predictable performance across a range of metals and thicknesses.

Practical tips for optimal results: match cutting speeds and feeds to the workpiece material, ensure adequate lubrication to dissipate heat, and use a stable drilling setup to prevent deflection on long reaches. For very deep holes, consider a supportive guide to maintain straightness and prolong insert life.
