Dormer Pramet R463 5.60 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 5.60 mm carbide drill is a long-series, coolant-fed tool built for demanding metalworking tasks. It’s designed for stainless steel and other heat-resistant alloys, delivering precise holes with reliable repeatability. With a DIN 6537 L shank and stepped geometry, it’s optimized for deep-hole applications while maintaining secure tool engagement.

Crafted from premium carbide and finished with a Titanium Aluminium Nitride (TiAlN) coating, this drill delivers longer tool life and enhanced performance when cutting harder materials. A dedicated CTW flute design with coolant feed adds strength and supports higher cutting speeds and feeds, helping you push through tough materials with confidence.

• 140° four-facet split point for precise starts: self-centers the hole on contact and reduces push force, improving alignment and reducing walk-offs during initial drilling.
• TiAlN coating for extended life: lowers wear and heat buildup, delivering better performance and longer service life when drilling stainless steel and other hard alloys.
• CTW flute design with coolant feed and stepped shank: optimized flute geometry and coolant delivery enable higher speeds and feeds, while the stepped shank provides secure, repeatable seating in toolholders for consistent results.

This high-performance drill is engineered to produce high-quality, accurate holes even at elevated speeds and feeds (h9 hole tolerance). By combining advanced geometry, durable coating, and robust carbide, it helps you reduce downtime, improve productivity, and achieve reliable results across challenging materials.
