Dormer Pramet R463 5.70 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 5.70 mm carbide drill is built for precision drilling in stainless steel and other heat‑resistant alloys. It features a 140° four‑facet split point for self‑centering and reduced push force, helping you start holes cleanly with less effort. With a TiAlN coating and a CTW flute design paired with coolant feed, this drill delivers longer tool life and the ability to run at higher speeds and feeds, even in demanding production environments. It’s designed to DIN 6537 L specifications for reliable fit and performance.

• 140° 4‑Facet Split Point: self‑centering starting geometry reduces the initial guidance force, promoting accurate hole initiation and clean holes from the first cut.
• TiAlN Coating on Premium Carbide: extended service life and improved performance when drilling stainless steel and other heat‑resistant materials, with better heat resistance and wear protection.
• CTW Flute Design with Coolant Feed: enhanced strength and chip evacuation at higher cutting speeds and feeds, plus effective coolant delivery to reduce heat and extend tool life.

This high‑performance, long‑series drill helps engineers, machinists, and hobbyists achieve consistent H9 tolerance holes with fewer tool changes and less downtime. By combining robust carbide, advanced coating, and a coolant‑fed flute, you get reliable, repeatable results that boost productivity and overall drilling quality on tough materials.
