Dormer Pramet R463 9.60 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 9.60 mm carbide drill is a coolant-fed, long-series tool built for demanding stainless steel and heat‑resistant alloys. With a DIN 6537 L shank and stepped design, it delivers extended reach and stable performance in deep holes, making it ideal for production runs and precision milling setups. The 140° four‑facet split point starts cleanly and self-centers, minimizing wandering and reducing the push force required to begin cutting.

• Self-centering 140° four-facet split point: Ensures easy starting and precise hole location, reducing wandering and the effort needed to start every drill even in tough materials.
• TiAlN coating for longer life: Extends tool life and maintains sharpness when drilling stainless steel and other hard materials, delivering consistent performance at higher speeds.
• CTW flute design with coolant feed and long-series stepped shank: Enhances strength and rigidity, enables higher cutting speeds and feeds, and provides reliable chip control and reach for deep holes in challenging alloys.

This high-performance carbide drill is designed to produce high-quality, accurate holes (h9 tolerance) even at elevated speeds and feeds. Its combination of a robust coating, specialized flute geometry, and a long, stable shank makes it a dependable choice for engineers, machinists, and technicians seeking repeatable results and longer tool life in demanding materials.
