Dormer Pramet R463 3.90 mm CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 3.90 mm carbide drill is a long-series, coolant-fed tool designed for fast, precise hole making in stainless steel and other heat‑resistant alloys. With a 140° four‑facet split point for self-centering, it starts cleanly and reduces the push force required to begin cutting. Built on premium carbide with a Titanium Aluminium Nitride (TiAlN) coating, this drill delivers longer service life and steadier performance under demanding conditions. The DIN 6537 L shank and specialized flute design support high‑speed, high‑feed drilling with reliable chip evacuation.

• Self-centering 140° four-facet split point: Ensures quick, accurate starts with less effort, improving hole position consistency from the first cut.
• TiAlN coating on premium carbide: Extends tool life and maintains sharpness when drilling stainless steel and other hard, heat‑resistant materials for fewer tool changes.
• Coolant-fed CTW flute design: Provides enhanced strength and allows higher speeds and feeds while delivering efficient chip evacuation for cleaner, more precise holes.

Together, these features enable reliable, high-quality hole making at speed, with durable performance that reduces downtime and improves workflow. Ideal for production and workshop use, the R463 drill delivers consistent tolerances and clean finishes in demanding materials, helping you finish jobs faster with confidence.
