Dormer Pramet R463 7.90 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 7.90 mm carbide drill (DIN 6537 L) is a high‑performance tooling solution designed for stainless steel and other heat‑resistant alloys. Featuring a 140° four‑facet split point for precise, self‑centering starts, this drill reduces start push force and helps you hit the exact hole location from the first cut. Its FORCE‑M stepped shank and long‑series geometry support deep reach and consistent stability in demanding applications.

With a TiAlN coating, this drill delivers extended life and reliable performance in tough materials, while a special flute design and coolant feed work together to improve strength, heat management, and chip evacuation. The result is higher cutting speeds and feeds without sacrificing hole quality, making it well suited to production environments that demand durable, accurate results.

• Self‑centering 140° 4‑Facet Split Point: Starts holes cleanly with reduced pushing force, minimizing wandering and improving first‑hole accuracy.
• TiAlN Coating for Extended Life: Enhances wear resistance and heat tolerance, delivering longer tool life when drilling stainless steel and high‑temperature alloys.
• CTW Flute Design with Coolant Feed: Optimized chip control and rigidity enable higher speeds and feeds while maintaining hole quality and surface finish.

Designed for reliability and precision, this drill helps you complete holes faster, reduce tool changes, and maintain tight tolerances (h9) across challenging materials. Its durable carbide construction, heat‑resistant coating, and coolant‑assisted design make it a dependable choice for professionals and hobbyists alike, supporting smooth workflows and consistent results in demanding manufacturing environments.
