Dormer Pramet R463 4.20 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 4.20 mm carbide drill with TiAlN coating, force‑m long series and stepped shank is a high‑performance option designed for precision metalworking. Sized at 4.20 mm and built for DIN 6537 L long series tools, it features a 140° four‑facet split point that starts holes cleanly with minimal wandering, making it ideal for stainless steel and other heat‑resistant alloys. Its stepped shank and coolant‑feed design provide reliable seating and effective heat management for deeper holes and demanding jobs.

• 140° 4‑Facet Split Point for Easy, Self‑Centering Start: Delivers clean entry and reduces push force, helping you achieve accurate holes from the first cut and minimize wandering in hard materials.
• TiAlN Coating for Longer Tool Life: Enhances wear resistance and thermal stability, boosting performance when drilling stainless steel and other tough alloys while extending tool life.
• CTW Flute Design with Coolant Feed for Strength and Speed: Provides greater rigidity, efficient chip evacuation, and the ability to run at higher speeds and feeds without sacrificing hole quality.

This high‑quality carbide drill is crafted to deliver consistent, high‑quality holes (H9 tolerance) at elevated cutting speeds, helping you reduce rework and downtime. The combination of the long series, stepped shank, and coolant integration makes it a dependable choice for production floors, job shops, and maintenance tasks where stainless steel and heat‑resistant materials are common.
