Dormer Pramet R463 8.30 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 8.30 mm carbide drill is a long-series, coolant-fed tool designed for deep-hole work in demanding metals. Its 140° four-facet split point starts holes cleanly and minimizes the push force required, helping to reduce wandering during entry. The 8.30 mm diameter suits precision work in stainless steel and other tough alloys, while the DIN 6537 L shank provides reliable reach and compatibility with common holders.

Equipped with a CTW flute design and coolant feed, the drill gains additional strength and rigidity, enabling higher cutting speeds and feeds without sacrificing hole quality. The Titanium Aluminium Nitride (TiAlN) coating further extends tool life and improves performance when drilling harder materials, complementing the premium carbide core engineered for stainless steel and heat-resistant super alloys.

• Self-centering 140° 4-Facet Split Point: Starts holes precisely with less pushing force, reducing wander and improving first-pass hole quality.
• TiAlN Coating for Extended Life: Increases tool life and maintains steady performance when drilling hard materials, lowering replacement frequency.
• CTW Flute Design with Coolant Feed: Delivers greater strength and allows higher speeds/feeds while delivering clean, accurate holes across demanding applications.

In practical use, this drill delivers reliable, high-quality results with fewer tool changes and productive speeds, making it a dependable choice for professional fabrication, maintenance, and precision drilling tasks in stainless steel and other heat-resistant alloys.
