Dormer Pramet R457 8.30 mm CARBIDE TIALN FORCE-X STEPPED SHANK COOLANT FEED SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R457 8.30 mm carbide drill is a high-performance cutting tool designed for precision hole making in metalworking projects. Built with a Force-X stepped shank, coolant feed, and a compact short-series form (X3D) meeting DIN 6537 K standards, this drill is ideal for engineers, machinists, and hobbyists who need reliable, accurate holes across a range of materials (steel, aluminium, stainless steel).

Its 140-degree four-facet split point guides the drill for self-centering entry and reduces push force, helping you start holes cleanly with less effort. The premium carbide core, TiAlN coating, and advanced flute design work together to deliver longer tool life, higher cutting speeds, and smoother finishes.

• 140° Four-Facet Split Point: Self-centering entry and reduced push force help you start holes cleanly with less effort, improving first-pass accuracy.
• TiAlN Coating for Longevity: Titanium Aluminum Nitride coating extends drill life and sustains high performance when drilling harder materials.
• Special Flute Design with Coolant Feed: ctw flute design and integrated coolant provide greater strength and allow higher speeds and feeds with efficient chip evacuation.

Designed to deliver consistent, high-quality holes quickly, this drill supports faster workflows, fewer tool changes, and dependable results across steel, aluminum, and stainless steel. Its precision tolerance (h9) keeps hole size consistent even at higher speeds and feeds, making it a reliable choice for production runs and demanding projects alike.
