The Dormer Pramet A977 8.00 mm HSS-E High-Performance Multi-Application Straight Shank Extra Long Series drill (DIN 1869 / 2) is purpose-built for deep-hole precision across a range of materials. Designed for professional workshops and production lines, this drill combines deep reach with dependable stability, making it a go-to choice when your projects demand accurate, long-reach drilling without sacrificing edge life.

• 130° point for easy starts and self-centering — minimizes wander and reduces the pushing force required to initiate holes, especially in challenging materials.
• Bright, anti-adhesion finish — helps prevent workpiece material from sticking to the cutting edge, promoting cleaner starts and smoother drilling operations.
• Parabolic flute design — engineered to evacuate chips efficiently and maintain straightness, enabling extra-deep holes to be drilled in a single pass with reduced clogging and heat buildup.
• Premium HSS-E material — cobalt-enriched composition delivers robust performance across a variety of workpieces, including steel, aluminum, and stainless steel, with longer tool life and consistent cutting action.
• Extra long length series — the extended reach is ideal for deep cavities, pockets, and applications where standard drills simply won’t reach, while preserving rigidity and alignment.
• Straight shank — provides a secure, uniform grip in common chucks, ensuring reliable concentricity and minimal runout during heavy-duty drilling.
• DIN 1869 / 2 compliance — built to standard specifications for dependable interchangeability with compatible tools and holders.

Ideal for machinists, fabricators, and maintenance professionals who routinely tackle deep-hole tasks, the A977 8.00 mm drill shines in applications like hole-touring in steel frames, deep-bore access in aluminum components, and stainless steel fabrication where reach and precision matter. When you need a single drill that can handle multiple materials with exceptional depth control, this extra-long, high-performance drill delivers consistent results, reduced rework, and a longer service life per bit.
