Dormer Pramet R463 4.10 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 4.10 mm carbide drill is a long-series (DIN 6537 L) drill with coolant feed, designed for deep, high-precision work in stainless steel and other heat‑resistant alloys. Its 140° 4‑facet split point helps the bit self‑center and start holes cleanly, reducing the push force required for a confident entry—ideal for challenging materials and tight tolerances.

Built with premium carbide and finished with a Titanium Aluminium Nitride (TiAlN) coating, this drill delivers extended tool life and dependable performance when drilling hard metals. The CTW flute design, combined with coolant delivery, adds extra strength and enables higher cutting speeds and feeds, helping you achieve consistent, high-quality holes with h9 tolerance.

• 140° 4-Facet Split Point: Self-centering lead-in for accurate hole starts, reducing wandering and the pushing effort required in tough materials.
• TiAlN Coating for Longer Life: Enhanced wear resistance and heat management extend tool life when drilling stainless steel and other hard alloys.
• CTW Flute Design with Coolant Feed: Stronger flute geometry plus coolant delivery supports higher speeds and feeds with reliable chip evacuation for cleaner, more consistent holes.

Designed for reliability and efficiency in professional shops and demanding workshops, the R463 drill combines precise hole quality with durable construction. Its long shank and standard DIN 6537 L compatibility let you reach deeper holes without frequent tool changes, while the optimized geometry and coating minimize wear and maximize productivity across stainless steels and high‑temperature alloys—all while delivering tight tolerances and repeatable results.
