Dormer Pramet R457 3/8 Inch CARBIDE TIALN FORCE-X STEPPED SHANK COOLANT FEED SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R457 is a 3/8 inch carbide drill designed for reliable, high-accuracy holemaking across a range of materials. Its short-series design with a stepped shank and integrated coolant feed makes it particularly well-suited for compact work areas and demanding setups that require steady, controlled cutting. Compatible with DIN 6537 K shanks, this drill is built to perform where precision matters.

• Self-Centering 140° Four-Facet Split Point: Promotes quick, accurate starts with less push force, reducing wandering and helping you achieve clean, true holes from the first cut.
• TiAlN Coating for Longer Tool Life: The Titanium Aluminium Nitride coating extends service life and enhances performance when drilling harder materials, delivering more holes per tool.
• CTW Flute Design with Coolant Feed: A strengthened flute pattern plus coolant delivery enables higher cutting speeds and feeds, improving reliability and allowing faster work without sacrificing hole quality.

This high-performance carbide drill is suitable for drilling steel, aluminium, and stainless steel, delivering consistent results with h9 hole tolerance. The combination of a reinforced flute design, coolant-assisted cutting, and a durable TiAlN-coated carbide core helps you complete precision holes more quickly, with fewer tool changes and less downtime, making it a trustworthy choice for both professional shops and serious hobby projects.
