Dormer Pramet R458 9/16 Inch CARBIDE TIALN FORCE-X STEPPED SHANK SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R458 is a 9/16 inch carbide drill engineered for professionals and serious hobbyists who need clean, accurate holes quickly across a range of metals. With a compact short shank and Force-X design, it’s built to perform reliably in tight spaces and demanding setups.

This drill combines a precision starter with a hard-wearing TiAlN coating and a robust flute geometry to deliver consistent results at higher speeds. It’s suitable for drilling steels, aluminum, and stainless steel, providing steady performance from first hole to last.

• Self-centering 140° four-facet split point: Starts exactly where you want, minimizes wandering, and reduces the push force required for a fast, controlled entry—improving hole accuracy from the first cut.
• TiAlN coating for longer life: The Titanium Aluminium Nitride layer resists heat and wear, extending tool life and maintaining sharpness when drilling harder materials.
• Force-X stepped shank with CTW flute design: Combines a rigid stepped shank with a strong flute geometry to increase strength, reduce vibration, and support higher cutting speeds and feeds for faster, reliable holes.

Designed to meet common DIN 6537 K shank standards and built around high-quality carbide, this drill delivers precise, high-quality holes with H9 tolerance and repeatable performance. It makes busy workflows smoother by reducing tool changes and rework, while maintaining consistency across jobs in steel, aluminum, and stainless steel.
