Dormer Pramet R457 5/32 Inch CARBIDE TIALN FORCE-X STEPPED SHANK COOLANT FEED SHORT SERIES (X3D) DRILL DIN 6537 K

Meet the Dormer Pramet R457 drill in 5/32 inch diameter, a carbide drill built for reliability in professional shops and DIY projects alike. It’s designed to deliver accurate, clean holes across a range of materials, including steel, aluminum, and stainless steel.

This tool combines a precise 140-degree four-facet split point for self-centering with a TiAlN coating that extends tool life and sustains performance under challenging drilling conditions. A CTW flute design with coolant feed increases strength and enables higher speeds and feeds, while the premium carbide material supports demanding applications and consistent results.

• 140° four-facet split point: Helps start holes on center with reduced push force, improving initial accuracy and reducing wandering.
• TiAlN coating: Increases service life and maintains sharpness when drilling harder materials, delivering more holes between tool changes.
• CTW flute design with coolant feed: Provides added drill strength, efficient chip evacuation, and the ability to run at higher speeds and feeds for cleaner, more consistent holes (h9 tolerance).

This drill is designed to deliver high-quality, accurate holes quickly and reliably, helping you reduce downtime, maintain consistent results, and expand the range of materials you can work with—without sacrificing precision or finish.
