Dormer Pramet R463 9.50 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 9.50 mm carbide drill is built for professionals who need reliable, high-quality holes in stainless steel and other heat‑resistant alloys. Its long-series, stepped shank and DIN 6537 L compatibility deliver deep reach and stable mounting in demanding setups, making it a dependable choice for precision work.

Equipped with a Titanium Aluminium Nitride (TiAlN) coating and a 140° four-facet split point, this drill starts accurately and resists wear in tough materials. The CTW flute design with coolant feed further enhances strength and allows higher cutting speeds and feeds for faster, cleaner hole production.

• 140° 4‑Facet Split Point for Self‑Centering and Reduced Start Push: Helps the drill start exactly on center, minimizes wandering, and lowers the guiding force required to begin a hole, improving first‑hole accuracy and operator comfort.
• TiAlN Coating for Longer Life and Hard Material Performance: Extends tool life when drilling stainless steel and heat‑resistant alloys, reduces heat buildup, and maintains cutting efficiency at higher temperatures.
• CTW Flute Design with Coolant Feed and Long-Series Stepped Shank: Delivers increased strength, supports higher speeds and feeds, and provides stable seating with extended reach in DIN 6537 L holders for deep, accurate holes.

Designed for demanding applications, the R463 drill delivers high-quality, repeatable results with h9 hole tolerance. Its robust carbide core, coating, and thoughtful geometry work together to reduce downtime, improve hole quality, and keep you productive across aerospace, automotive, and general manufacturing tasks.
