Dormer Pramet R463 29/64 Inch CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 is a 29/64 inch carbide drill designed for high-demand work with stainless steel and other heat-resistant alloys. It features a long DIN 6537 L shank and a coolant-fed design, making it ideal for deep-hole applications and extended reach in challenging materials.

Its 140-degree, 4-facet split point helps the drill start precisely and reduces the push force required to begin cutting, promoting better first-pass accuracy. The Titanium Aluminium Nitride (TiAlN) coating extends tool life and enhances performance on tougher materials, while the CTW flute design, combined with coolant delivery, adds strength and enables higher cutting speeds and feeds for dependable, consistent results.

• Self-Centering 140° 4-Facet Split Point: Reduces start-up push force and improves first-pass hole accuracy, helping you drill cleaner, more consistent holes from the very first cut.
• TiAlN Coating for Longer Life: Hard-wearing coating that minimizes wear, increasing tool life and performance when drilling stainless steel and other hard alloys.
• CTW Flute Design with Coolant Feed: Optimized geometry plus coolant delivery delivers greater strength, supports higher speeds and feeds, and helps maintain stable, reliable hole quality at scale.

engineered for professionals who demand precise, repeatable results in demanding materials. The R463 delivers high-quality, accurate holes (within h9 tolerance) even at elevated speeds and feeds, helping you complete jobs faster with fewer tool changes and less rework. Its long-series shank and premium carbide composition make it a dependable choice for deep-hole drilling in stainless steel and other tough alloys.
