Dormer Pramet A976 11.00 mm HSS-E High-Performance Multi-Application Straight Shank Extra Long Drill (DIN 1869 / 1) is built for demanding deep-hole drilling across a wide range of materials. This drill bit combines precision geometry with durable construction to deliver consistent, long-lasting performance in tough production environments.

Why this 11.00 mm HSS-E extra-long drill stands out

• 130° point for self-centering and easy starts: The precise point reduces walk and lowers the push force required, helping you achieve clean starts and accurate hole alignment, even in challenging workpieces.
• Bright finish for smooth cutting and chip flow: The bright, non-stick edge minimizes material adhesion and reduces built-up edge, resulting in smoother drilling and less dwell time between holes.
• Parabolic flute design for deep-hole drilling: The unique flute geometry evacuates chips efficiently and maintains stable feed in very deep holes, allowing you to drill longer without retracting to clear chips.
• Premium HSS-E material for versatility: HSS-E (high-speed steel with cobalt content) delivers higher hot hardness and wear resistance, making it suitable for steel, aluminium, and stainless steel workpieces without frequent tool changes.
• Extra-long length for reach where others stop: When you need to drill through thick materials, reach through tall jaws, or access deep cavities, this extra-long series gives you the tolerance you need without compromising rigidity.
• DIN 1869 / 1 compliance and straight shank: Built to ISO drilling standards with a straight shank that fits a wide range of chucks and CNC spindles for reliable, consistent performance in production environments.

This multi-application drill is ideal for machinists, fabricators, and workshop technicians who demand consistency across a variety of materials—from robust steel to lighter aluminum profiles. Whether you’re creating through-holes or blind holes in thick plates, the A976 11.00 mm HSS-E drill delivers predictable hole quality, reduced tool wear, and fewer tool changes throughout your job.

Practical tips for best results: start with a sharp pilot or center punch, use a proper coolant or cutting fluid to manage heat, and adopt a controlled pecking approach when drilling deeper holes. Maintain the tool’s cutting edge by avoiding overheating and removing chips regularly to preserve the characteristic benefits of parabolic flute geometry.
