Dormer Pramet R459 3.50 mm CARBIDE TIALN FORCE-X STEPPED SHANK LONG SERIES (X8D) DRILL

The Dormer Pramet R459 3.50 mm carbide drill combines a premium carbide core with a TiAlN coating for dependable metal drilling. Its 140° four-facet split point self-centers and minimizes the starting force, helping you begin holes cleanly and accurately. This drill is versatile enough for materials including steel, aluminium, and stainless steel, delivering consistent results across your projects.

Designed for demanding work, the FORCE-X stepped shank and long-series (X8D) geometry provide rigid chuck engagement and reliable hole quality even in deeper workpieces. A CTW flute design with coolant feed further strengthens the tool and enables higher cutting speeds and feeds, supporting faster material removal and improved surface finish.

• 140° 4-Facet Split Point: Self-centering start reduces wandering and lowers the push force needed to begin a hole, delivering cleaner, more precise results.
• TiAlN Coating for Longer Life: Increases tool life and maintains sharpness when drilling harder materials, reducing frequency of tool changes.
• Special CTW Flute Design with Coolant Feed: Enhances strength and allows higher speeds and feeds for faster drilling and better hole quality in a variety of materials.

This drill helps you improve throughput with reliable, high-quality holes at speed. Its rugged carbide core and coating extend life in versatile metalworking tasks, while the stepped shank and long-series design ensure stable performance in standard chucks. With a 3.50 mm diameter and h9 hole tolerance, it’s a precise, dependable choice for both production and on-site projects.
