Dormer Pramet R463 9.40 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 9.40 mm carbide drill is a high-performance tool designed for precision hole making in stainless steel and other heat‑resistant alloys. With a long-series shank (DIN 6537 L) and integrated coolant feed, this drill is built to handle demanding jobs in workshops, job shops, and production environments.

Engineered for reliability, it features a 140-degree four‑facet split point for self-centering and reduced start force, a Titanium Aluminium Nitride (TiAlN) coating to extend wear life, and a CTW flute design with coolant delivery to enable higher cutting speeds and feeds while maintaining strength and stability.

• 140° four‑facet split point: provides self-centering starts with less push force, improving first‑pass hole quality and reducing wandering.
• TiAlN coating for longer life: delivers superior wear resistance and cooler cutting when drilling stainless steel and other hard alloys, enhancing tool life in tough materials.
• CTW flute design with coolant feed: increases rigidity and supports higher speeds and feeds, while efficient coolant delivery improves chip evacuation and finish.

This high‑performance drill produces consistent, high‑quality holes with tight tolerances (h9) even at elevated speeds, helping you complete projects faster with fewer tool changes. Its premium carbide composition and coating are tailored for demanding applications, giving you reliable results and confident production in stainless steel and heat‑resistant alloys.
