Dormer Pramet R463 5.20 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 5.20 mm carbide drill is designed for demanding metalworking tasks, especially in stainless steel and other heat‑resistant alloys. It features a long‑series design with a stepped shank and integrated coolant feed, helping you reach deeper holes with stable, accurate results from the first hole.

Geared for professionals across engineering, manufacturing, and workshops, this drill balances performance and reliability to support high‑speed, high‑accuracy drilling without frequent tool changes.

• 140° 4‑facet split point for easy starting: Self‑centering point reduces wandering at the start and lowers the push force needed, helping you drill cleanly into tough materials.
• TiAlN coating for extended life: Titanium Aluminium Nitride coating delivers superior wear resistance and heat tolerance, keeping the edge sharp longer when drilling stainless steel and hard alloys.
• Special flute design with coolant feed: CTW flute design and integrated coolant feed enhance strength and chip evacuation, enabling higher cutting speeds and feeds while preserving hole quality.

This combination of premium carbide, coating, and optimized geometry translates to more consistent hole quality (h9 tolerance), improved productivity, and reliable performance in deep-hole applications. The long series, stepped shank and DIN 6537 L compatibility provide stable mounting and reach, helping you complete demanding tasks with fewer tool changes and greater confidence.
