Dormer Pramet R463 21/64 Inch CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

Meet the Dormer Pramet R463 21/64 inch Carbide TiAlN Force-M Stepped Shank Coolant Feed Long Series drill. Designed for stainless steel and other heat-resistant alloys, it starts holes with a 140° four-facet split point that self-centers and reduces the push force needed, delivering clean, accurate starts. The result is reliable entry and consistent hole quality right from the first cut.

With a TiAlN coating for longer tool life, a CTW flute design with coolant feed to boost strength and efficiency, and a stepped long shank for stability, this premium carbide drill maintains high performance at higher speeds and feeds. DIN 6537 L compatibility ensures easy integration into standard tool setups, and its h9 hole tolerance supports precise, repeatable results in demanding applications.

• Self-centering 140° four-facet point: Starts holes cleanly with reduced push force, minimizing wandering and improving first-pass accuracy on stainless steel and tough alloys.
• TiAlN coating for longer life: Enhances wear resistance to extend tool life, maintaining performance during longer production runs and challenging materials.
• CTW flute design with coolant feed: Optimized chip evacuation and coolant delivery enable higher cutting speeds and feeds while delivering strong, consistent hole finishes.

This combination of geometry, coating, and design delivers reliable, high-quality results across demanding applications. The R463 drill helps improve throughput with fewer tool changes, smoother operation in stainless and hard alloys, and repeatable hole accuracy (h9 tolerance) while fitting neatly into standard DIN 6537 L tooling ecosystems and offering the stability of a stepped shank.
