Dormer Pramet R463 3.20 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 3.20 mm carbide drill is built for professionals who require precision and reliability in tough materials. With a long-series design, stepped shank, and DIN 6537 L compatibility, this drill is ideal for deeper holes and demanding production work in stainless steel and heat-resistant alloys.

Its 140-degree 4-facet split point keeps starts true and reduces push force, while a TiAlN coating boosts tool life. A special flute design with coolant feed further strengthens the drill and enables higher cutting speeds and feeds for efficient, high-quality hole production.

• Self-centering 140° four-facet split point: Starts holes true with less push force and reduces wandering, especially on stainless steel and hard alloys.
• TiAlN-coated premium carbide: Extends tool life and maintains cutting performance in heat‑intensive materials, improving overall throughput.
• Coolant‑fed flute design for higher speeds: Enhances strength and rigidity, enabling higher cutting speeds and feeds for faster, cleaner holes.

In practice, this drill delivers consistent, accurate holes at high speeds with reduced downtime. It achieves tight hole tolerance (h9) in challenging materials, thanks to the combination of coating, flute design, and a robust carbide core. The R463 drill supports reliable performance across production runs, field work, and demanding fabrication tasks.
