Dormer Pramet R463 15.80 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 15.80 mm carbide drill is a high‑performance cutting tool designed for engineers, fabricators, and serious hobbyists who need reliable, precise holes in stainless steels and other heat‑resistant alloys. Built for long series tasks with a stepped shank and coolant feed, it fits DIN 6537 L holders to support demanding applications and consistent results.

Its 140‑degree, 4‑facet split point helps start holes cleanly with less push force, promoting true starts and reduced wandering. The Titanium Aluminium Nitride (TiAlN) coating extends tool life and enhances performance when drilling harder materials. A CTW flute design with coolant feed increases strength and enables higher cutting speeds and feeds, delivering productive performance in challenging materials.

• Self-centering 140° 4‑facet split point: starts holes cleanly with less push force, reducing wander and improving first‑cut accuracy.
• TiAlN coating for longer life: resists wear on stainless steels and other heat‑resistant alloys, delivering more holes per edge and lower regrind frequency.
• Long-series stepped shank with coolant feed: secure engagement in extended reach applications while coolant delivery enhances chip evacuation and heat management for higher speeds and feeds.

With this drill, you’ll achieve consistent, high‑quality holes (h9 tolerance) at speed, extend tool life to reduce downtime, and maintain reliable performance across challenging materials. Its premium carbide core, TiAlN coating, CTW flute design, and coolant‑feed system work together to improve productivity and finish across production and workshop environments.
