Dormer Pramet R463 11.30 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

Engineered for demanding metalworking jobs, the Dormer Pramet R463 is a 11.30 mm carbide drill designed to tackle stainless steel and other heat‑resistant alloys. Its long-series design with a stepped shank (DIN 6537 L) provides stable, precise holes and reliable performance across deep-hole applications.

Featuring a 140-degree four‑facet split point for self‑centering, a TiAlN coating to extend tool life, and a CTW flute design with coolant feed, this drill starts cleanly, lasts longer, and can run at higher speeds and feeds for faster, more consistent hole making.

• Self-centering 140° four‑facet split point: Improves start accuracy, reduces push force, and minimizes wandering during entry into stainless steels and hard alloys.
• TiAlN coating for extended life: Boosts wear resistance and heat tolerance, delivering longer tool life and steadier performance on tough materials.
• CTW flute design with coolant feed: Enhances strength and chip evacuation, enabling higher cutting speeds and feeds with reliable, clean holes.

This combination delivers high-quality, accurate holes at elevated speeds, maintaining h9 hole tolerance while reducing downtime through longer tool life and dependable performance in challenging production environments. The result is faster cycles, fewer reworks, and confidence that your stainless steel and heat‑resistant workpieces are drilled to spec with each pass.
