• Applications: Shoulder milling and slot milling in free-machining steel, plain carbon steel, and copper or copper alloys

Designed for durability and precision, this end mill leverages powder-metallurgical HSS-E to resist wear during longer cuts while maintaining a sharp edge. The 30° helix and 12° rake angle promote smooth entry and efficient chip flow, helping to reduce cutting forces and improve surface finish on challenging materials. The Weldon 10 mm shank ensures secure clamping in standard tool holders, making it a dependable choice for extended shoulder and slot milling tasks. Whether you’re machining free-machining steels or copper alloys, the C273 delivers consistent performance with a bright finish that resists built-up edge and helps keep feeds and speeds steady across production runs.
