Dormer Pramet R457 7.60 mm CARBIDE TIALN FORCE-X STEPPED SHANK COOLANT FEED SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R457 7.60 mm carbide TiAlN FORCE-X drill is a high-performance tool designed for professionals who demand reliable, precise holes across a range of materials. With a short shank and DIN 6537 K compatibility, this 7.60 mm drill is ideal for compact setups, tight spaces, and fast changeovers in mechanical, automotive, and fabrication applications.

Engineered for demanding drilling, it features a 140-degree, 4-facet split point for self-centering starts that reduce wandering and minimize push force. The Titanium Aluminium Nitride coating extends service life and delivers better wear resistance when drilling harder steels and alloys. A special CTW flute design with coolant feed enhances strength and enables higher cutting speeds and feeds for productive, accurate holemaking.

• 140° four-facet split point: Self-centering starting action reduces wandering and lowers starting push force for reliable, precise hole initiation.
• TiAlN coating for extended life: Hardened coating boosts wear resistance, prolonging tool life and improving performance on harder materials.
• CTW flute design with coolant feed: Optimized flute geometry plus coolant delivery enhances chip evacuation, lowers heat, and supports higher speeds and feeds for efficient machining.

This high-performance drill helps you achieve consistent hole quality with tight tolerances (h9) while boosting throughput. Its premium carbide core, protective TiAlN coating, and coolant-enabled design work together to reduce rework, shorten cycle times, and improve overall machining results—making it a dependable choice for professional shops and demanding projects alike.
