Meet the Dormer Pramet A976 7.50 mm HSS-E High Perf Multi-App Straight Shank Extra Long Series drill. Designed for serious depth, this drill combines precision, longevity, and versatile material compatibility in a single, reliable tool. Whether you’re a professional shop or a hands-on maker, you’ll feel the difference when you need to reach deep into a job with clean, accurate results.

Why this drill stands out

• 130° point for self-centering – The sharpened tip guides itself into the workpiece, minimizing wandering and reducing the push force required to start a hole. The result is smoother starts and tighter hole alignment, even on challenging materials.
• Bright finish – A coated, shiny edge that minimizes friction and helps prevent workpiece material from sticking to the cutting edge, improving hole quality and reducing built-up edge.
• Parabolic flute design – Specifically engineered to evacuate chips efficiently, this flute geometry enables drilling extra deep holes in a single pass without sacrificing hole accuracy or surface finish.
• Premium HSS-E material – High-Performance Steel Alloy (HSS-E) delivers superior wear resistance and toughness, suitable for drilling a wide range of materials, including steel, aluminum, and stainless steel.
• Extra long length – Built for very deep holes and applications where extended reach is essential, this drill keeps rigidity and stability intact even when you’re working far from the operator’s end.
• DIN 1869 compatibility – Meets standard industrial specifications for reliable interchangeability and predictable performance in professional settings.

Ideal use cases

Use this drill when you need a long-reach solution that still delivers accurate, straight holes. It excels in automotive repair, machinery maintenance, aerospace component fabrication, and any project where deep hole drilling is required without multiple passes. The combination of a 7.50 mm diameter and an extra-long body makes it perfect for tapping through thick sections or plunging into deep workpieces where standard-length drills fall short.

Practical guidance for best results

• Pair with appropriate speeds and feeds for the material at hand—slower speeds and ample lubrication for harder steels, higher speeds for aluminum where heat buildup is manageable.
• Expect clean starts thanks to the 130° point; pause briefly to clear chips if drilling to extreme depths, preserving cutting edge integrity.
• Use peck drilling techniques to maintain chip evacuation when drilling very deep holes, reducing friction and heat buildup.
• Inspect the cutting edge after heavy usage and re-sharpen if needed to maintain alignment and hole quality.
