Dormer Pramet A976 3.50 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK EXTRA LONG SERIES (1) DRILL DIN 1869 / 1

Dormer Pramet A976 3.50 mm HSS-E High Performance Multi-App Straight Shank Extra Long Drill (DIN 1869 / 1) The Dormer Pramet A976 is engineered for precision metalworking, delivering dependable performance across a range of materials with a single, purpose-built drill. This 3.50 mm HSS-E high-performance drill combines advanced geometry and a long-reach design to tackle deep-hole applications without compromise. 130° point for effortless starts The 130-degree point geometry is purpose-built for self-centering action, helping the drill find alignment quickly and reducing the push force required to start cutting. That means smoother entry, less wandering, and more consistent hole placement—especially in tight tooling setups or when working with challenging workpieces. Bright finish for cleaner starts and smoother chips A bright finish on the cutting edge minimizes material adhesion at entry, promoting cleaner starts and steadier chip flow. Reduced sticking translates to fewer pulling forces on the drill and more stable cutting conditions, which contributes to longer tool life and cleaner bore surfaces. Parabolic flute design enables deep-hole drilling in a single pass The parabolic flute geometry is optimized for chip evacuation during deep-hole drilling. This design supports efficient removal of material as the drill penetrates taller workpieces, enabling extra-deep drilling in a single pass. The result is fewer tool changes, lower cycle times, and reliable straightness even in deep bores. Premium HSS-E for versatile material capability Built from premium HSS-E (high-speed steel enhanced), this drill is suited for a broad spectrum of metals, including steel, aluminum, and stainless steel. The combination of strength and heat resistance helps maintain cutting edge geometry under higher heat, reducing edge dulling and promoting consistent hole quality across materials. Extra Long length for extended reach and deep holes As part of the Extra Long length series, this drill is designed for applications where reach matters. Whether you’re drilling deep bores in automotive components, heavy machinery housing, or aerospace fixtures, the longer flute length provides the depth you need without compromising rigidity or accuracy. Who benefits most - Machinists and toolmakers who regularly drill deep holes in metal workpieces - Job shops and fabrication shops that need versatile tooling capable of handling steel, aluminum, and stainless steel with a single drill - Applications demanding precise centering, clean entry, and reliable hole quality over long depths Why this drill stands out - Targeted 130° point minimizes wandering and reduces starting force, improving first-pass accuracy - Parabolic flute delivers efficient chip evacuation for deep-hole operations, reducing the need for multiple passes - Bright-edge finish lowers sticking and improves surface finish at entry - Premium HSS-E construction supports multiple materials with consistent performance - Extra-long reach unlocks deeper holes and extended applications without changing tools Usage notes and practical tips - Match spindle speed and feed to the material being drilled; start with conservative parameters and increase gradually while monitoring heat buildup - Use a suitable cutting fluid or coolant to extend edge life when drilling harder metals - Secure the workpiece firmly and consider a center punch to minimize walk during initiation - For very deep holes, drill slowly with a steady feed to prevent chip packing and maintain straightness - Inspect the drill tip periodically for wear and replace when cutting efficiency diminishes to protect hole quality < p>
