Meet the Dormer Pramet A976 10.00 mm HSS-E High Performance Multi-Application Straight Shank Extra Long Series drill—the go-to choice when you need robust drilling power with unmatched reach. This drill is engineered for accuracy, reliability, and sustained performance in demanding metalworking environments.

Precision you can feel in every hole

• 130° point geometry promotes self-centering starts and lowers push forces, delivering cleaner entry cuts and reducing chatter as you begin each hole.
• Bright finish minimizes material adhesion on the cutting edge, helping to prevent built-up edge and extend tool life in tough materials.
• Special parabolic flute design optimizes chip evacuation for extra-deep holes, enabling a single-pass drill where others stall or require pecking.
• Premium HSS-E material provides solid wear resistance across a range of metals—including steel, aluminium, and stainless steel—so you can rely on this drill in mixed-material applications.
• Extra-long length series delivers extended reach for deep cavities and hard-to-access workpieces, while maintaining straightness and stability under load.
• Straight shank with DIN 1869 / 1 compatibility ensures dependable clamping and smooth operation in standard chucks and fixtures.

Why this drill fits real-world workflows

When you’re machining components with deep features—valves, housings, engine blocks, or fixtures—the A976 drill shines. The combination of long reach and parabolic flute means you can drill deeper without sacrificing hole quality or tool life. It’s ideal for job shops and production environments where changing tools mid-process is costly or impractical.

Practical tips for best results

• Match speed and feed to the material: moderate RPM followed by a steady, controlled feed yields clean holes with minimal heat buildup.
• Use appropriate cutting fluid to cool the cut and extend tool life, especially on stainless steel and high-hardness materials.
• For very deep holes, use shallow pecks to break chips and prevent re-cutting, then resume full-depth drilling.
• Secure the workpiece firmly to minimize deflection due to the drill’s extended length.
• Inspect the drill regularly for wear and re-sharpen or replace as needed to maintain hole accuracy and surface finish.

Ideal for professionals who demand depth, precision, and durability

The Dormer Pramet A976 drill is a versatile workhorse for machinists, fabricators, and engineers who frequently encounter deep, precise holes across a variety of materials. Its robust HSS-E composition, combined with the 130° point and parabolic flute, delivers dependable performance that helps you meet tight tolerances, reduce cycle times, and lower tooling costs over the life of the job.
