Dormer Pramet R457 9.30 mm CARBIDE TIALN FORCE-X STEPPED SHANK COOLANT FEED SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R457 9.30 mm carbide drill is built for precise, reliable hole-making across common metals like steel, aluminium, and stainless steel. Featuring a TiAlN coating, a 140° four-facet split point, and a coolant-fed stepped shank, it starts cleanly, lasts longer, and stays accurate at higher speeds.

• Self-Centering 140° Split Point: This point geometry helps the drill center itself as it enters the workpiece, reducing wandering and lowering the push force required to start a hole, for cleaner starts and less operator effort.
• TiAlN Coating for Longer Tool Life: The Titanium Aluminium Nitride coating reduces wear, delivering longer service life and better performance when drilling harder materials or higher-speed operations.
• Premium Carbide with Coolant-Feed Flute Design: Hard, durable carbide handles tough materials and, combined with a dedicated coolant-fed flute design, supports higher cutting speeds and feeds while maintaining hole quality.

This drill is designed to boost productivity by delivering high-quality, accurate holes at speed, with less effort and fewer tool changes. Its versatile material compatibility and robust construction make it suitable for production environments, workshops, or DIY projects, helping you reduce downtime and improve results with repeatable precision (h9 hole tolerance).
