Dormer Pramet R463 9.70 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 9.70 mm carbide drill is engineered for dependable, high‑quality hole making in stainless steel and other heat‑resistant alloys. Featuring a 140° four‑facet split point, it starts holes with precision and minimizes wandering and push force right from the first cut. The 9.70 mm diameter is paired with a DIN 6537 L long shank for deep holes and versatility in demanding applications.

Designed for performance, this drill combines a Titanium Aluminium Nitride (TiAlN) coating with premium carbide to boost tool life and maintain cutting efficiency under tougher materials. A specialized flute design with integrated coolant feed delivers increased strength, enabling higher speeds and feeds while maintaining hole quality.

• Self-centering 140° four‑facet split point: starts holes cleanly with less thrust, reducing wandering and improving hole accuracy from the first cut.
• TiAlN coating for longer life: enhances wear resistance and sustained performance when drilling stainless steel and other hard alloys, lowering tool changes and downtime.
• Long, coolant‑fed CTW flute design (DIN 6537 L): provides deeper reach with improved rigidity, supports higher speeds and feeds, and promotes efficient chip evacuation for reliable, high‑quality holes.

This drill is built to deliver consistent, high‑precision results (h9 hole tolerance) even at elevated speeds and feeds. The combination of premium carbide material, TiAlN coating, and advanced flute geometry helps you complete demanding jobs faster, with fewer tool changes and more predictable outcomes across a range of tough materials.
