Dormer Pramet R457 N4 CARBIDE TIALN FORCE-X STEPPED SHANK COOLANT FEED SHORT SERIES (X3D) DRILL DIN 6537 K

Designed for engineers, shop-floor buyers, tradespeople, and serious hobbyists, the Dormer Pramet R457 N4 carbide drill is a high-performance drilling solution that delivers fast, accurate holes across a range of materials. With a 140° four-facet split point for self-centering, a TiAlN coating for longer life, and a CTW flute design with coolant feed, it enables higher cutting speeds and feeds while maintaining h9 hole tolerance. The FORCE-X stepped shank provides a secure, repeatable grip in your drill chuck for demanding manufacturing and assembly work.

• 140° four‑facet split point: Self-centering starts reduce wandering and lower the push force, helping you begin holes cleanly and maintain accuracy even on tougher materials.
• TiAlN coating for longer life: Hardened protective coating increases tool life, reduces wear, and improves performance when drilling harder metals like stainless steel and high-strength alloys.
• CTW flute design with coolant feed: Stronger flute geometry combined with coolant delivery enables higher speeds and feeds, better chip evacuation, and cooler, more consistent hole quality.

This drill is built for dependable performance in everyday production and precision work alike. It delivers consistent hole quality, reduces downtime, and extends tool life across steel, aluminum, and stainless steel, making it a trusted choice for engineers, machinists, and workshop professionals.
