Dormer Pramet R463 11.40 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 11.40 mm carbide drill is a precision cutting tool designed for stainless steel and other heat‑resistant alloys. Built with a long-series design and a FORCE-M stepped shank, it delivers reliable deep‑hole performance and robust engagement in standard toolholders (DIN 6537 L). The coolant‑feed feature enhances chip control and reduces heat, helping you maintain productivity in demanding shops.

Its 140‑degree, 4‑facet split point self‑centers the drill for cleaner entry and lowers the push force required to start the hole, enabling consistent starts even in tough materials. The Titanium Aluminum Nitride (TiAlN) coating extends tool life and preserves edge sharpness when drilling hard metals. A CTW flute design with coolant feed adds strength and supports higher cutting speeds and feeds, delivering reliable, high‑quality holes with tight tolerances, including h9 hole tolerance.

• 140° 4‑facet split point: Self‑centering entry with reduced start‑up thrust for cleaner, more reliable hole starts.
• TiAlN coating: Increases wear resistance and tool life, maintaining sharpness on stainless steel and other hard materials.
• CTW flute design with coolant feed: Enhanced rigidity and chip evacuation, enabling higher speeds and feeds for faster, consistent results.

This drill is engineered to improve throughput in demanding applications, delivering consistent hole quality, longer tool life, and dependable performance across production runs. Its robust carbide composition, combined with the long-series design and coolant delivery, helps you reduce downtime, maintain accuracy, and complete projects with confidence.
