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

The Dormer Pramet R458 I carbide drill is designed for demanding metalworking tasks, delivering precise, high-quality holes across steel, aluminium, and stainless steel. Its 140-degree four-facet split point helps start the cut cleanly with minimal wandering, reducing the push force needed to begin drilling.

Coated with Titanium Aluminium Nitride (TiAlN), this drill extends tool life and maintains strong performance when drilling harder materials. The special CTW flute design adds exceptional strength and supports higher cutting speeds and feeds, while the premium carbide construction ensures reliable results and consistent hole quality, including tight tolerances (H9) in DIN 6537 K sizing.

• Self-centering 140° four-facet split point: Starts cleanly, minimizes wander, and reduces the push force needed to begin drilling for accurate holes from the first cut.
• TiAlN coating for longer tool life: Improves wear resistance and heat tolerance, extending life when working with harder materials and challenging drilling conditions.
• CTW flute design on premium carbide: Adds strength and enables higher speeds and feeds, delivering consistent hole quality and faster cycle times.

This combination of geometry, coating, and flute design makes the R458 I drill a dependable choice for production runs, job shops, and DIY projects that demand precision, durability, and reliable results across a range of metals. It’s built to deliver accurate holes with tight tolerances while reducing downtime and tool change frequency.
