Dormer Pramet R457 N3 CARBIDE TIALN FORCE-X STEPPED SHANK COOLANT FEED SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R457 N3 Carbide TiAlN Force-X Stepped Shank Coolant Feed Short Series Drill (DIN 6537 K) is a high‑performance carbide drill designed for engineers, machinists, and hobbyists who need reliable, precise holes across a range of materials. Its 140° four‑facet split point helps self‑center the start while reducing the push force, the TiAlN coating extends tool life and improves performance on harder materials, and a CTW flute design with coolant feed delivers higher speeds and feeds with strengthened cutting and efficient chip flow.

• Self-centering 140° four-facet split point: Starts holes accurately with less effort, reducing wander and improving first-pass hole quality.
• TiAlN coating for longer life: Enhances wear resistance and maintains sharpness when drilling harder materials like stainless steel, boosting tool life and reducing replacements.
• CTW flute design with coolant feed: Improves strength and chip evacuation, enabling higher cutting speeds and feeds while delivering steady, reliable performance with a stepping shank for stable seating.

This drill is built for real-world productivity: it delivers high‑quality, h9 tolerance holes across steel, aluminum, and stainless steel, even at higher speeds. The short-series, stepped shank and DIN 6537 K compatibility simplify setup and toolholder integration, helping you reduce downtime and maintain consistent results on demanding jobs.
