Dormer Pramet R457 N29 CARBIDE TIALN FORCE-X STEPPED SHANK COOLANT FEED SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R457 N29 carbide drill is a compact, coolant-fed drill designed for reliable holemaking across a wide range of materials. With a DIN 6537 K shank, it fits into standard toolholders for fast, productive setups.

Built for professionals and serious hobbyists alike, this premium carbide drill features a 140-degree four-facet split point for self-centering starts and reduced push force, a TiAlN coating for extended tool life, and a CTW flute design with coolant feed to boost strength and enable higher speeds and feeds on steel, aluminum, and stainless steel.

• Self-centering 140° 4‑facet split point: Starts true on contact, reduces push force, and improves hole start accuracy for clean, reliable holes.
• TiAlN coating for longer tool life: Enhances wear resistance and helps maintain sharpness when drilling harder materials, reducing rework and downtime.
• CTW flute design with coolant feed: Increases tool strength and allows higher cutting speeds and feeds, while efficient cooling and chip evacuation improve hole quality and surface finish.

With the R457, you get fast, accurate holes across common metals, reduced downtime from wear or misalignment, and consistent results you can trust on production runs or DIY projects. The combination of premium carbide, TiAlN coating, and advanced flute geometry delivers dependable performance, fewer tool changes, and a smooth workflow from setup to finish.
