The Dormer Pramet R458 is a 10.20 mm carbide drill with a DIN 6537 K shank, designed for serious metalworking. Part of the FORCE-X stepped-shank short series (X3D), it’s built for professional machinists, engineers, and fabricators who need dependable, repeatable performance across a range of materials including steel, aluminium, and stainless steel.

With a precise start and rugged construction, this drill is optimized for higher speeds and feeds while delivering clean, accurate holes. The 140° four-facet split point, TiAlN coating, and premium carbide core work together to reduce setup time and extend tool life in demanding applications.

• Self-centering, 140° four-facet split point: Enables immediate, accurate hole entry with reduced push force and minimal wandering, improving first-pass hole quality on a variety of metals.
• TiAlN coating for longer drill life: The Titanium Aluminum Nitride coating boosts wear resistance and heat tolerance, helping the tool last longer when drilling harder materials or performing high-speed operations.
• CTW flute design with premium carbide for high-speed, precise holes: The CTW flute design adds strength and supports higher cutting speeds and feeds, delivering consistently accurate holes with h9 tolerance across steel, aluminium, and stainless steel.

Together, this drill minimizes downtime, reduces rework, and supports reliable, high-quality results from the first hole to the last—making it a versatile choice for workshop and production environments alike.
