Dormer Pramet R463 5.30 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 5.30 mm carbide drill is a precision tool designed for stainless steel and other heat‑resistant alloys. With a stepped shank and DIN 6537 L long length, it reaches deep holes while staying secure in standard toolholders.

Built for demanding work, this drill combines a self-centering tip, a wear‑resistant TiAlN coating, and a coolant‑fed CTW flute design to deliver clean, accurate holes at high speeds and feeds.

• 140° four‑facet split point: Provides easy, self‑centering entry and reduces the forces needed to start the hole, helping prevent wandering and ensuring a precise start even in challenging materials.
• TiAlN coating for extended life: The Titanium Aluminium Nitride layer cuts wear and maintains edge sharpness at higher temperatures, boosting tool life when drilling stainless steel and other hard alloys.
• CTW flute design with coolant feed: Optimized flute geometry plus coolant delivery increases drill rigidity, enables higher cutting speeds and feeds, and improves chip evacuation for consistent performance.

Designed to deliver consistent, high‑quality results with tight tolerances (H9) in demanding materials, the R463 drill supports deep holes with its long DIN 6537 L length and stepped shank. The combination of carbide hardness and TiAlN coating helps you push speeds and feeds with confidence, while the coolant‑fed flute design keeps temperatures down and chips clear for reliable production drilling.
