Designed for professional machinists and demanding fabrication tasks, the Dormer Pramet A977 6.50 mm HSS-E High Performance Multi-Application Straight Shank Extra Long Drill is engineered to conquer long, deep-hole work with consistent accuracy. This drill combines robust material, precise geometry, and extended reach to excel across a wide range of metals.

• 130° point — enables self-centering entry and reduces the push force required to start cutting, helping you achieve clean starts and accurate hole placement.
• Bright finish — minimizes adhesion of workpiece material to the cutting edge, supporting smoother drilling and easier edge retention during lengthy operations.
• Special parabolic flute design — optimized for chip evacuation in deep holes, allowing deeper holes to be drilled in a single pass with fewer interruptions.
• Premium HSS-E material — built for durability and versatility, suitable for drilling a variety of materials including steel, aluminium, and stainless steel.
• Extra Long length series — the extended reach is purpose-built for very deep holes and applications where space or access is limited, without sacrificing rigidity.
• Straight shank — delivers reliable grip and compatibility with common drill chucks and straight-shank tooling systems.
• DIN 1869 / 2 compliant — a trusted standard that ensures compatibility with established tooling ecosystems.

This drill is ideal for engineers and shops tackling automotive components, aerospace fixtures, and heavy fabrications where deep-hole drilling is essential. It delivers versatility across multiple materials and maintains consistent hole quality from start to finish, reducing the need for multiple tools and setup changes.

Compared with shorter or single-material drills, the A977’s extra-long length and parabolic flute design offer improved reach and efficient chip clearance in deep-hole scenarios, helping you maintain productivity on time-sensitive projects.

Practical tips for best results: ensure proper work-holding and rigid setup to maximize the effectiveness of the extra-long form, use appropriate spindle speed for the material being drilled, and rely on the 130° point for accurate starts to protect edge life on tougher metals.
