Dormer Pramet R457 N21 CARBIDE TIALN FORCE-X STEPPED SHANK COOLANT FEED SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R457 N21 carbide drill is a premium DIN 6537 K tool built for reliable, precise hole-making across steel, aluminium, and stainless steel. This is a FORCE-X short-series drill with a stepped shank and coolant feed, designed to perform in tight spaces while delivering consistent starts and stable cuts. It’s engineered for production environments and professional workshops where accuracy and uptime matter, with the ability to maintain H9 hole tolerance even at higher speeds.

Key features work together to maximize live performance: a 140° four-facet split point for self-centering and reduced start-up push force; a robust Titanium Aluminium Nitride coating that extends tool life and improves performance on harder materials; and a special flute design with coolant feed that increases strength and enables higher cutting speeds and feeds without compromising finish.

• 140° four-facet split point: Self-centering geometry minimizes wandering at startup and reduces the push force needed, producing clean, accurate holes from the first cut.
• TiAlN coating for extended life: The Titanium Aluminium Nitride coating dramatically increases wear resistance and heat tolerance, delivering longer service life across steel, aluminium, and stainless steel.
• Special flute design with coolant feed: Enhanced flute geometry plus coolant delivery improves rigidity, supports higher speeds and feeds, and delivers better chip evacuation for a smoother finish.

With its premium carbide core and thoughtfully engineered features, this drill helps you complete holes with high quality and consistency, reduces downtime from tool wear, and improves overall workflow in both production and DIY settings. The result is dependable performance, repeatable results, and peace of mind that you’re using a tool designed for demanding drilling tasks.
