Dormer Pramet R457 N27 CARBIDE TIALN FORCE-X STEPPED SHANK COOLANT FEED SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R457 N27 carbide drill with TiAlN coating is built for serious drilling tasks across a range of materials. Designed with a FORCE-X stepped shank and coolant feed, this short-series drill delivers reliable performance in compact setups, making it a strong choice for engineers, machinists, and workshop teams working with steel, aluminum, or stainless steel. Its DIN 6537 K shank ensures compatibility with standard toolholders and quick, confident engagement in your machine.

• Self-centering 140° 4‑facet split point: starts cleanly with minimal wandering, reducing push force and helping you achieve accurate holes from the first cut.
• TiAlN coating for longer tool life: significantly enhances wear resistance, enabling more holes between regrinds and better performance when drilling harder materials.
• CTW flute design with coolant feed: delivers greater strength and stability at higher cutting speeds and feeds, while efficient coolant delivery improves chip control and thermal management.

This drill is engineered for consistent, high-quality results, capable of producing precise holes with H9 tolerances even at elevated speeds and feeds. Its premium carbide core handles a variety of materials—from steels to aluminum and stainless steel—while the stepped shank and coolant features help reduce downtime and improve overall workflow in demanding manufacturing environments.
