Meet the Dormer Pramet A976 7.00 mm HSS-E High Performance Multi-Application Straight Shank Extra Long Series drill (DIN 1869/1) — a long-reach, precision-driven solution for metalworking that demands depth and reliability.

Designed for demanding applications, this 7.00 mm drill bit blends aggressive performance with thoughtful geometry to tackle tough materials and deep holes with ease. Here’s what sets it apart:

• 130-degree point for self-centering — minimizes wandering at start-up and reduces push force, delivering clean, accurate entry into steel, aluminum, and stainless steel.
• Bright finish — helps prevent workpiece material from sticking to the cutting edge, improving chip flow and reducing built-up edge during extended drilling sessions.
• Parabolic flute design — optimized for drilling extra deep holes in a single pass, with efficient chip evacuation to maintain cutting efficiency as the hole deepens.
• Premium HSS-E material — high-speed steel with enhanced wear resistance and heat tolerance, enabling reliable performance across a wide range of metals beyond basic steel or aluminum.
• Extra Long length series with straight shank — engineered for maximum reach without compromising straightness or control, ideal for deep-hole work, long cavities, or components with limited access.
• DIN 1869 / 1 designation — crafted to standard dimensions for compatibility with common drill chucks and holders, making replacement straightforward in busy shops.

Who benefits most? This drill bit is a natural fit for machine shops, automotive service centers, mold making, aerospace fabrication, and any environment where long through-holes must be drilled accurately without frequent bit changes.

Use scenarios to consider:

• Long through-holes in steel frames, assemblies, or machinery housings where access is limited from one side.
• Aluminium components requiring precise starts and efficient chip clearance for clean finishes.
• Stainless steel parts where耐wear resistance and stable performance across heat are essential.

Practical tips for best results: rely on the 130° point to begin the cut with minimal wandering, maintain a steady cutting speed appropriate to the material, and let the parabolic flutes carry out efficient chip evacuation. For very deep holes, keep the workpiece well-lubricated and monitor chip clearance to sustain smooth drilling through the full length of the bit.
