The Dormer Pramet A976 is a purpose-built drill bit designed for serious deep-hole work without the guesswork. Sized at 6.20 mm, this HSS-E high-performance drill leverages a precision-focused geometry to deliver dependable results across a range of materials, from soft aluminum to tough stainless steels, making it a versatile centerpiece in any machining toolkit.

Key features that matter in real-world drilling

• 130-degree point — promotes immediate self-centering and lowers the push force required to start a hole, reducing wander and allowing smoother entry even in interrupted cuts.
• Bright finish — minimizes built-up edge and material sticking on the cutting edge, helping maintain clean holes and extend tool life in difficult workpieces.
• Special parabolic flute design — engineered to evacuate chips efficiently, enabling deeper holes in a single pass while reducing clogging and heat buildup.
• Premium HSS-E material — combines toughness and wear resistance to handle a broad spectrum of materials, including steel, aluminum, and stainless steel, with consistent performance.
• Extra-long length — ideal for drilling very deep holes or accessing recessed features where standard bits can’t reach, while preserving rigidity for accurate hole geometry.
• DIN 1869 / 1 compliant — ensures compatibility with common drill chucks and holders, simplifying tool pairing and replacement in busy shop environments.

Who benefits from the A976 drill bit

If you routinely tackle deep drilling tasks, this bit is a capable partner for engineering, maintenance, and fabrication workloads. It’s particularly well-suited for deep bores in fabrication assemblies, automotive components, tooling steel, and parts requiring precise inner diameters with clean finishes. The multi-application design means you won’t need a different bit for every material type—the A976 covers steel, aluminum, and stainless steel with reliable consistency.

Practical usage guidance

For optimal results, pair the A976 with appropriate feed rates and steady cutting speeds suitable for the material at hand. Keep cutting fluid or coolant flowing to prevent overheating, and use solid workholding to minimize vibration during deep-hole drilling. If you’re drilling particularly hard or gummy materials, a gentle pilot hole can help establish true alignment before the full-depth pass.

Why this isn’t just another drill

Where many drills struggle with accuracy and chip evacuation in deep holes, the A976 delivers a balanced combination of precision entry, efficient chip removal, and extended reach. That means fewer re-drills, tighter tolerances, and a lower risk of exit-wall mistakes—freeing you to focus on the next steps of your project with confidence.
