Dormer Pramet R463 6.90 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 6.90 mm carbide drill is a TiAlN-coated, long-series tool built for demanding stainless steel and heat-resistant alloy work. Featuring a stepped shank, coolant feed, and DIN 6537 L compatibility, it delivers deep-hole capability with reliable starts and clean hole quality. This makes it a versatile choice for engineers, machinists, fabricators, and hobbyists who need precise holes in tough materials.

Designed for high productivity, it maintains hole accuracy at higher speeds and feeds, with a self-centering 140° four-facet split point that reduces push force and wandering across tough metals. The premium carbide core, combined with TiAlN coating and the CTW flute design, delivers longer tool life and enhanced performance for stainless steel and other heat-resistant super alloys.

• Self-centering 140° four-facet split point: Starts the hole cleanly, reduces push force, and minimizes wandering for accurate, repeatable hole locations.
• TiAlN-coated premium carbide: Extends tool life and maintains cutting performance when drilling hard materials like stainless steel and high-temperature alloys, reducing replacement frequency.
• CTW flute design with coolant feed: Supports higher cutting speeds and feeds while improving chip evacuation and resistance to heat buildup for reliable, consistent holes.

Designed for real-world production, this drill helps you achieve deeper, more accurate holes with fewer tool changes and less rework. The combination of rugged carbide, protective TiAlN coating, and efficient coolant delivery translates to faster cycle times, better hole quality (h9 tolerance), and reliable performance across demanding applications—from precision fabrication to heavy-duty machining.
