Dormer Pramet R463 3.80 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 3.80 mm carbide TiAlN Force-M stepped shank coolant feed long series drill (DIN 6537 L) is a high-performance tool built for stainless steel and other heat‑resistant alloys. It’s designed for engineers, machinists, and hobbyists who need reliable, precise holes with minimal downtime across demanding projects.

With a 140-degree 4-facet split point, it starts quickly with self-centering action, reducing push force and wandering. The Titanium Aluminium Nitride coating boosts wear resistance and tool life when drilling tougher materials. A ctw flute design with integrated coolant feed adds strength and enables higher cutting speeds and feeds, helping you finish jobs faster without sacrificing hole quality.

• 140° four‑facet split point for easy starting: Self-centering action reduces wandering and lowers the pushing effort for cleaner, more accurate holes.
• TiAlN coating for extended life: Increases wear resistance and maintains sharpness on stainless steel and hard alloys, reducing tool changes and downtime.
• ctw flute design with coolant feed for high-speed performance: Enhances strength and coolant delivery, enabling higher speeds and feeds with efficient chip evacuation for cleaner holes.

Designed to deliver consistent hole quality within H9 tolerance, this drill combines premium carbide with durable coating and a robust stepped shank to support production runs and diverse workshop use. The long-series length and secure shank engagement ensure dependable alignment in standard holders, while the coolant system manages heat to extend tool life and preserve precision across multiple workpieces.
