Dormer Pramet R463 8.00 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 8.00 mm carbide drill is built for precision holemaking in stainless steel and other heat‑resistant alloys. It combines a 140° four‑facet split point for self‑centering with a TiAlN coating to extend tool life, plus a CTW flute design with coolant feed that supports higher speeds and feeds. The long-series shank fits standard DIN 6537 L holders, enabling deeper holes and consistent performance in demanding applications.

• Precision self-centering split point: 140-degree, four-facet geometry helps the drill start accurately and reduces the push force required for a clean entry.
• TiAlN-coated premium carbide: Titanium Aluminium Nitride coating increases tool life and boosts performance when drilling stainless steel and other heat‑resistant alloys.
• CTW flute design with coolant feed: Special flute geometry and coolant delivery provide greater strength and allow higher cutting speeds and feeds while maintaining smooth chip evacuation.

In practice, this drill delivers high-quality, accurate holes even at elevated speeds and feeds (h9 hole tolerance). The robust carbide core, extended life from the TiAlN coating, and the coolant‑fed, long‑shank design work together to reduce downtime, improve consistency, and enhance overall workflow in demanding metalworking tasks.
