Meet the Dormer Pramet A976 12.50 mm HSS-E high-performance drill—the go-to choice for demanding metalworking tasks that demand depth, precision, and reliability. Built as a multi-application, straight-shank solution, this drill is designed to tackle a broad spectrum of materials with one tool that stays true from start to finish.

Key features that deliver real results

• 130° point promotes self-centering and reduces the push force needed to begin cutting, helping you achieve cleaner starts and straighter holes with less effort.
• Bright finish minimizes material adhesion on the cutting edge, reducing built-up edge and extending tool life in challenging workpieces.
• Special parabolic flute design optimizes chip evacuation for deep-hole drilling, enabling you to bore very deep holes in a single pass without clogging or heat buildup.
• Premium HSS-E material offers impressive toughness and wear resistance, making it suitable for drilling steel, aluminium, and stainless steel alike.
• Extra long length series provides increased reach for deep or recessed holes, expanding the range of applications without compromising rigidity.
• Straight shank ensures secure, repeatable clamping in most CNC and drilling setups, helping maintain accuracy across multiple operations.
• DIN 1869 / 1 standard marks a reliable, industry-recognized specification, ensuring compatibility with common drilling machines and collets.

The A976 drill is purpose-built for jobs where depth, accuracy, and throughput matter. Use it for precision deep-hole drilling in automotive components, mold making, structural metalwork, and general fabrication—wherever you need clean starting points, minimized push force, and reliable material performance across steel, aluminium, and stainless steel.

Why this drill stands out in real-world use

Unlike lighter-duty bits, the A976’s 12.50 mm diameter combined with an extra-long form delivers a practical balance between rigidity and reach. The self-centering point reduces wander on initial contact, which is especially valuable when you’re drilling through tough or uneven workpieces. The parabolic flute design not only clears chips efficiently but also helps maintain steady cutting action during long, deep holes, improvingHole quality and process consistency over extended drilling cycles.

Practical tips for best results

• Choose appropriate spindle speed and feed rate for the material being drilled; start conservative and increase as you monitor heat and chip clearance.
• Use a suitable cutting fluid or coolant when drilling metals to extend tool life and improve surface finish.
• Secure the workpiece firmly and verify alignment before starting a deep-hole operation to maximize precision with the A976.
