Dormer Pramet R457 11.30 mm CARBIDE TIALN FORCE-X STEPPED SHANK COOLANT FEED SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R457 11.30 mm carbide drill combines durability and precision for a wide range of metalworking tasks. With a 11.30 mm diameter and a DIN 6537 K stepped shank, this short-series drill is designed for reliable performance in steel, aluminum, and stainless steel, delivering consistent holes at higher speeds and feeds.

A 140° four-facet split point helps the drill start true and self-center, reducing push force during entry and minimizing wandering. The Titanium Aluminum Nitride (TiAlN) coating extends tool life and improves performance on harder materials, while the CTW flute design with coolant feed enhances strength and enables higher cutting speeds and feeds for efficient, dependable drilling.

• 140° Split Point for Easy Starts: Self-centering action reduces wandering and lowers the effort required to begin each hole, improving accuracy and reducing start-up risk.
• TiAlN Coating for Longer Tool Life: Hardened coating resists heat and wear, delivering longer service life across steel, aluminium, and stainless steel with consistent hole quality.
• CTW Flute Design with Coolant Feed: Structured flute geometry plus coolant delivery boosts strength, allows higher speeds and feeds, and enhances chip evacuation for cleaner, more reliable holes.

Designed to meet real-world manufacturing needs, this drill delivers high-quality, repeatable holes with tight tolerances (h9) while maintaining dependable performance across a variety of common materials. The combination of a stepped DIN 6537 K shank, robust carbide core, and advanced coating ensures fewer tool changes, smoother operation, and consistent results in professional workshops, job shops, and production floors.
