Dormer Pramet R463 4.05 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 4.05 mm carbide drill is a long-series (DIN 6537 L) tool designed for demanding holemaking in stainless steel and other heat‑resistant alloys. Its precise 140° four‑facet split point provides fast, self‑centering starts, reducing the push force required and helping you achieve clean holes right from the first cut.

• Self-centering 140° four-facet split point: Starts true with less effort, improving hole accuracy and reducing wander in tough materials.
• TiAlN coating for extended life: Delivers superior wear resistance and heat performance, extending tool life when drilling stainless steel and hard alloys.
• Advanced flute design with coolant feed: Supports higher cutting speeds and feeds, enhances rigidity and heat management, and delivers consistently precise holes (h9 tolerance) in demanding workpieces.

Designed for reliability and productivity, this drill pairs a premium carbide core with an efficient coolant‑fed flute system to minimize downtime, reduce tool changes, and maintain high hole quality across deep or complex holepaths. The long shank provides stable engagement in deeper applications, making it a dependable choice for both precision work and high‑throughput production.
