Dormer Pramet R457 N18 CARBIDE TIALN FORCE-X STEPPED SHANK COOLANT FEED SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R457 N18 carbide drill is a high‑performance, coolant‑fed tool designed for professional metalworking. With a DIN 6537 K stepped shank and premium carbide, it delivers consistent, accurate holes across a wide range of materials—including steel, aluminum, and stainless steel.

Its 140‑degree, four‑facet split point centers itself at the start, reducing push force and improving hole startup. A Titanium Aluminium Nitride (TiAlN) coating extends tool life and enhances performance in harder materials. The CTW flute design with coolant feed adds strength and allows higher cutting speeds and feeds for faster production with clean, precise holes (h9 tolerance).

• Self-centering 140° four-facet point: Starts holes quickly with less push force, minimizes wandering, and speeds up setup for accurate hole placement.
• TiAlN coating for longer life: Provides superior wear and heat resistance, extending drill life and maintaining sharpness when drilling harder materials.
• CTW flute design with coolant feed for high-speed drilling: Enhances flute rigidity and coolant delivery, enabling higher speeds and feeds while delivering clean holes within tight tolerances.

Together, this drill delivers reliable performance across common metals, reducing downtime and boosting throughput. The DIN 6537 K shank ensures secure mounting in standard holders, while the carbide core and TiAlN coating help you maintain precision from first hole to last. Ideal for engineers, machinists, and hobbyists who demand consistent results and durable tooling in everyday drilling tasks.
