Dormer Pramet R463 10.20 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

Meet the Dormer Pramet R463 10.20 mm carbide drill, a precision tool designed for demanding metalworking tasks. Built from premium carbide and finished with a Titanium Aluminium Nitride (TiAlN) coating, it delivers longer tool life and reliable performance when drilling stainless steel and other heat‑resistant alloys. The 140-degree, four‑facet split point promotes self‑centering starts and reduces the push force needed to begin cutting, helping you achieve clean holes with minimal wandering.

Designed for reach and durability, this long‑series drill features a stepped shank and integrated coolant feed, enabling higher speeds and feeds while maintaining control and hole quality. The DIN 6537 L shank standard ensures compatibility with common tool holders, making it a dependable choice for workshops, fabrication shops, and on‑site work.

• 140° 4‑Facet Split Point for Self‑Centering: Starts holes precisely with less entry force, reducing wandering and improving first‑pass hole accuracy.
• TiAlN Coating for Longer Tool Life: Increases wear resistance and performance when drilling stainless steel and other heat‑resistant alloys.
• Special Flute Design with Coolant Feed (ctw flute design): Provides enhanced strength, better chip control, and supports higher cutting speeds and feeds while keeping holes clean.

This drill delivers dependable, high‑quality results in a wide range of applications. The combination of a premium carbide core, TiAlN coating, coolant‑fed flute design, and a long series with stepped shank makes it a reliable choice for achieving consistent hole quality (h9 tolerance) at higher production speeds, while maintaining tool life and minimizing downtime.
