Dormer Pramet R463 5.90 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 5.90 mm carbide drill is a precision, coolant‑fed tool designed for high‑speed production in stainless steel and other heat‑resistant alloys. It features a long‑series shank (DIN 6537 L) and a 5.90 mm diameter, making it ideal for deeper holes and repeatable results in challenging materials.

• 140° 4‑Facet Split Point: Provides a self‑centering start and reduces the push force required, helping you achieve clean, accurate holes from the first cut.
• TiAlN‑Coated Premium Carbide: Extends tool life and maintains sharpness when drilling hard materials, delivering reliable performance in stainless steel and other tough alloys.
• Special Flute Design with Coolant Feed: Enhances strength and allows higher speeds and feeds, while efficient chip evacuation supports deeper holes and consistent hole quality.

When used in compatible equipment, this drill delivers precise, repeatable holes (including tight h9 tolerances) with reduced downtime and longer service life. The combination of a robust carbide core, TiAlN coating, and coolant‑fed flute design helps you complete demanding fabrication and production tasks more predictably, improving workflow and overall drilling performance.
