Dormer Pramet R457 N16 CARBIDE TIALN FORCE-X STEPPED SHANK COOLANT FEED SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R457 N16 carbide drill with DIN 6537 K shank is a high‑performance tool built for professionals and serious hobbyists who demand reliable, precise holes in metalworking tasks. Its short-series design, Force‑X stepped shank, and coolant‑fed geometry deliver consistent hole quality across steel, aluminium and stainless steel in production and workshop environments.

Key advantages come from a 140‑degree, four‑facet split point that self-centers and reduces the initial push force; a Titanium Aluminium Nitride (TiAlN) coating that extends tool life and maintains cutting performance on tougher materials; and a specialized flute design with coolant feed that strengthens the drill and enables higher cutting speeds and feeds.

• Self-centering 140° four-facet split point: Starts holes precisely with less push force, reducing wandering and improving first‑pass accuracy.
• TiAlN coating for longer life: The coating resists heat and wear, delivering extended tool life and consistent performance when drilling steel, aluminium, and stainless steel.
• Force‑X stepped shank with coolant feed and advanced flute design: Enhanced rigidity and efficient chip evacuation allow higher speeds and feeds, boosting reliability in demanding applications.

Designed to fit standard DIN 6537 K shanks, this drill enables repeatable, high‑quality hole production with tight tolerances (h9). Its premium carbide construction, combined with the TiAlN coating and optimized flute geometry, helps reduce downtime, extend tool life, and deliver dependable results across a variety of metals, making it a trusted choice for fabrication, maintenance, and engineering projects.
