Dormer Pramet R463 3/16 Inch CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 3/16 in carbide drill is a high‑performance long‑series tool designed for stainless steel and other hard alloys. With a stepped shank and coolant feed, it delivers consistent, accurate holes in demanding workpieces while maintaining tool stability and reliability across extended runs.

Equipped with a 140° four‑facet split point for self‑centering and reduced push force, plus a TiAlN coating that extends tool life and improves performance on hard materials, this drill is built to last. The CTW flute design with coolant feed adds extra strength and enables higher cutting speeds and feeds, so you can tackle tougher jobs with confidence. Crafted from premium carbide, it’s specifically optimized for stainless steel and heat‑resistant alloys and delivers high‑quality, accurate holes with tight tolerances (H9).

• 140° 4‑Facet Self‑Centering Point: Starts holes precisely where you aim, reduces entry force, and minimizes wandering for true, clean results.
• TiAlN Coating for Extended Life: Increases wear resistance and maintains sharpness when drilling stainless steel and hard alloys, cutting downtime and improving throughput.
• CTW Flute Design with Coolant Feed and Stepped Shank: Provides added strength, supports higher speeds and feeds, and ensures secure drive and efficient chip evacuation in tough materials.

This drill is built to elevate productivity in professional shops and robust hobby workflows alike. Expect dependable, repeatable hole quality at high speeds and feeds, reduced tool changes, and smooth integration with standard DIN 6537 L holders. The result is consistent performance, tight H9 tolerances, and greater overall drilling reliability across demanding applications.
