Dormer Pramet A976 12.00 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK EXTRA LONG SERIES (1) DRILL DIN 1869 / 1

Dormer Pramet A976 12.00 mm HSS-E High-Performance Multi-Application Straight Shank Extra Long Drill (DIN 1869) is built for demanding deep-hole work without compromise. This precision twist drill combines a robust design with geometry that makes challenging holes achievable in a single pass, even in tougher materials.

Key features that set this drill apart:

• 130° point for self-centering – minimizes wandering at entry and reduces the push force required to start the hole, helping you maintain accuracy from the first cut.
• Bright finish – crafted to resist sticking and built to stay cleaner during long runs, which translates to fewer interruptions for edge maintenance.
• Special parabolic flute design – optimized for drilling very deep holes in a single pass, improving chip evacuation and reducing clogging in long deployments.
• Premium HSS-E material – a durable high-speed steel grade that delivers reliable performance across a wide range of materials, including steel, aluminum, and stainless steel.
• Extra-long length series – engineered for reach where standard drills fall short, making it ideal for deep cavities, through-holes, and applications that demand extended reach without sacrificing rigidity.

What problems does it solve? This drill excels where deep-hole accuracy matters—think automotive housings, hydraulic manifolds, aerospace components, or any job requiring long, clean through-holes. The A976’s geometry minimizes deflection, while the extended length ensures you can access recessed or tightly spaced features without a tool change.

Ideal applications include:

• Long through-holes in thicker workpieces where conventional tools can’t reach
• Multi-position or multi-pass tasks that benefit from a single-pass deep-hole capability

Compared to standard drills, the A976’s combination of a precision 130° point, bright finish, and parabolic flute design translates to faster setup, fewer chatter issues, and more consistent hole quality in demanding workflows. Its HSS-E construction handles repeated use across various materials, reducing the need for tool changes and downtime.

Practical tips for best results:

• Use appropriate cutting fluid to extend tool life and improve surface finish, especially in stainless steel.
• Start with a light pilot hole if precise centering is critical, then proceed to full-depth drilling with steady feed.
• Match your spindle speed to the material being drilled and the drill diameter to optimize chip evacuation and edge life.
• Employ solid clamping and rigid fixturing to take advantage of the extra reach without introducing deflection.

With Dormer Pramet’s A976, you get a reliable, long-reach drill designed to tackle deep-hole tasks across a spectrum of materials. It’s the smart choice for professionals who demand precision, versatility, and consistent performance from a single, high-quality drill suitable for DIN 1869 applications.
