Dormer Pramet R458 9.40 mm CARBIDE TIALN FORCE-X STEPPED SHANK SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R458 carbide drill delivers precise, repeatable holes with a 9.40 mm diameter and a DIN 6537 K stepped shank (X3D) for secure, reliable performance in common tool holders. Crafted for professional workloads, it’s designed to handle a range of materials while maintaining accurate hole quality.

The drill features a 140° four-facet split point that self-centers and reduces entry push force, helping you start holes cleanly and with less wandering. A Titanium Aluminium Nitride (TiAlN) coating extends tool life and improves performance when drilling harder materials. The CTW flute design adds strength to the body, enabling higher cutting speeds and feeds while maintaining consistent hole quality and close tolerances (h9).

• 140° split point for precise starting: Self-centers the drill and reduces entry force, minimizing wandering and speeding up accurate hole initiation.
• TiAlN coating for extended life: Shrugs off heat and wear, delivering longer tool life and steadier performance on steel, stainless steel, and aluminum.
• CTW flute design for higher speeds and feeds: Enhances rigidity and material removal efficiency, enabling faster drilling with consistent, high-quality holes.

Designed for reliable results across a range of engineering materials, this high-performance carbide drill combines durability, precision, and efficiency to support faster workflows, reduced downtime, and repeatable hole quality in everyday manufacturing and fabrication tasks.
