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

The Dormer Pramet R457 J carbide drill is a coolant-fed, short-series drill engineered for reliable, precise hole making. Designed to fit DIN 6537 K shanks, it combines premium carbide with a TiAlN coating to deliver standout life and performance across steel, aluminium, and stainless steel. The result is dependable drilling that starts true and maintains accuracy throughout the cut.

Key design features work together to boost productivity: a 140° four-facet split point helps with self-centering, reducing push force for easier starts; a TiAlN coating extends tool life and improves cutting performance on harder materials; and a special CTW flute design with coolant feed increases strength while allowing higher cutting speeds and feeds.

• Self-Centering 140° Four-Facet Split Point: Delivers clean starts with less wandering and reduced starting force, improving first-pass hole quality and reducing rework.
• TiAlN Coating for Longer Life: Titanium Aluminum Nitride coating enhances wear resistance and heat tolerance, extending tool life across tough materials and demanding jobs.
• CTW Flute Design with Coolant Feed: Optimized flute geometry plus integrated coolant delivery boosts rigidity, chip evacuation, and allows higher speeds and feeds for faster, more consistent holes.

This high-performance carbide drill is built for demanding applications where dependable hole quality (including H9 tolerance) matters. Its combination of durable materials, advanced coating, and coolant-assisted design helps reduce downtime, minimize tool changes, and deliver accurate results across a wide range of common machining tasks.
