Dormer Pramet R463 3.60 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 3.60 mm carbide drill is a precision, coolant-fed tool designed for stainless steel and other hard-to-machine alloys. With a long DIN 6537 L shank and a stepped design, it’s built for extended reach jobs and demanding metalworking environments while delivering reliable, accurate holes.

Its 140-degree, four-facet split point provides self-centering starts and reduces the push force required, helping you begin cuts cleanly. The Titanium Aluminium Nitride (TiAlN) coating extends tool life and maintains performance when drilling harder materials, improving consistency over time. A specialized flute design with coolant feed supports higher cutting speeds and feeds, while increasing drill strength for demanding applications.

• Self-centering 140° four-facet split point: facilitates easy starting and reduces your effort during initial engagement, helping you achieve true, round holes with minimal wandering.
• TiAlN coating: dramatically increases tool life and maintains sharpness in stainless steels and other heat‑resistant alloys, reducing replacement downtime.
• Coolant-fed flute design: enables higher speeds and feeds, improves chip evacuation, and delivers reliable hole quality with tight tolerances (h9) even in tough materials.

In real-world use, this drill translates to fewer reworks, faster cycle times, and consistent hole quality across production runs. The combination of premium carbide, TiAlN coating, and a coolant-enabled design makes the R463 a dependable choice for precision metalwork, from prototype builds to high-volume manufacturing.
