Dormer Pramet A976 3.40 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK EXTRA LONG SERIES (1) DRILL DIN 1869 / 1

The Dormer Pramet A976 3.40 mm HSS-E High Performance Multi-App Straight Shank Extra Long Drill is engineered to deliver precise, reliable results in demanding drilling tasks. With a compact 3.40 mm diameter, this drill handles tight tolerances and intricate holes where accuracy matters most, while the extra-long form provides exceptional reach for deep work without compromising rigidity.

Key features that boost every drilling project

• 130° point promotes self-centering and minimizes the pushing force, helping you start holes cleanly and reduce deflection on tough materials.
• Bright finish minimizes material sticking at the cutting edge, improving chip flow and reducing built-up edge for smoother drilling sessions.
• Parabolic flute design enables efficient chip evacuation and strong rigidity when drilling very deep holes in a single pass, reducing the need for multi-step drilling.
• Premium HSS-E material delivers dependable performance across a wide range of materials, including steel, aluminum, and stainless steel, with improved wear resistance and longer tool life.
• Extra long length series is purpose-built for drilling very deep holes and applications requiring extended reach, while maintaining shank stability and cutting performance.
• DIN 1869 compliance ensures consistent dimensions and compatibility with standard drill heads and fixtures for seamless integration into existing tooling setups.

Designed for multi-application drilling, this drill excels in engineering shops, fabrication workshops, and production lines where deep holes, tight tolerances, and reliable performance are non-negotiable. The combination of a precise tip, efficient flute geometry, and robust HSS-E construction makes it a versatile choice for automotive components, hydraulic assemblies, or any project demanding accurate, deep-hole penetration.

Why this drill stands out in real-world use

• When you need to drill deep without re-positioning, the extra-long length keeps you moving forward instead of stopping to change tools.
• Working with mixed materials—steel, aluminum, or stainless—benefits from the tool’s wear resistance and balanced cutting action, reducing tool changes and downtime.
• The self-centering tip and efficient chip evacuation reduce nap and chatter, delivering cleaner holes with minimal finishing work.

Practical tips for optimal results: start with a light, steady feed to establish a clean center, use appropriate coolant or lubrication to manage heat on tougher materials, and employ periodic pecking to clear chips when drilling very deep holes. With the Dormer Pramet A976, you get a precision-focused, dependable drill that keeps up with demanding workloads and tight production schedules.
