Dormer Pramet R454 8.90 mm CARBIDE TIALN FORCE-X STEPPED SHANK STANDARD SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R454 8.90 mm carbide drill is a versatile, high-precision tool designed for engineers, technicians, and hobbyists who demand reliable, accurate holes across a wide range of materials. Built from premium carbide and finished with a Titanium Aluminium Nitride (TiAlN) coating, it delivers long tool life and steady performance, even at higher speeds.

This drill features a stepped shank compatible with common chucks (DIN 6537 L) and a CTW flute design that provides added strength while enabling higher cutting speeds and feeds, delivering faster hole production without sacrificing hole quality.

• 4-facet 140° split point: Self-centering start reduces wandering and lowers push force, helping you begin holes cleanly and improve first-pass accuracy.
• TiAlN coating for longer life: The titanium aluminium nitride coating enhances wear resistance, extending tool life and sustaining sharpness when drilling harder materials.
• CTW flute design for higher speeds and strength: The specialized flute geometry adds rigidity and supports higher cutting speeds and feeds for faster, consistent hole production.

This combination of durability, accuracy, and ease of use makes the R454 a dependable choice for everyday workshop use, production runs, and precision finishing. It helps reduce downtime, minimizes rework, and consistently delivers clean, dimensionally stable holes that meet tight tolerances (h9).
