Value Collection 724-1245 Roughing End Mill 1 in 5 Flute Cobalt

Product Description

The VALUE COLLECTION 724-1245 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a TiN coating, it handles tough ferrous metals and hard alloys where standard HSS tooling falls short. The 1-inch cutting diameter and 5-flute geometry produce a serrated chip-breaking action that reduces cutting forces, lowers heat buildup, and extends tool life in heavy roughing passes. The right-hand cut and right-hand flute configuration suits standard CNC and manual vertical milling setups. Machinists and tool-and-die professionals use this end mill for roughing slots, profiles, and pockets before finishing passes.

This end mill is suited for roughing operations on ferrous metals, stainless steel, and high-temperature alloys in both job-shop and production environments. The 4-inch length of cut provides deep reach for pocketing and profiling without requiring extended-reach tooling. The 3/4-inch shank seats in standard ER or side-lock toolholders common to vertical machining centers and manual knee mills. It is a single-end tool, so it is replaced rather than reground at the opposite end when the cutting edge is worn.

Key Features

• M42 cobalt construction for increased red hardness and wear resistance over standard M2 HSS
• TiN coating reduces friction and extends edge life in ferrous and stainless applications
• 5-flute roughing geometry breaks chips and reduces radial cutting forces in heavy passes
• Centercutting design allows plunge entry without a pre-drilled hole
• Right-hand cut and right-hand flute for use in conventional CNC and manual milling spindles
• 4-inch length of cut enables deep pocket and profile roughing in a single setup

Compatibility

Designed for use in standard 3/4-inch toolholders including ER collet chucks, Weldon side-lock holders, and hydraulic chucks on vertical machining centers and manual knee mills.

Installation Notes

Installation and tool changes must be performed with the machine spindle stopped and the control in an e-stop or locked-out state per OSHA lockout/tagout procedures. Seat the 3/4-inch shank fully in the toolholder and torque the retention mechanism to the toolholder manufacturer specification before running. Verify runout with a dial indicator before taking the first cut, as excessive runout accelerates edge wear on multi-flute roughing tools. This tool is intended for roughing passes only; follow with a finishing end mill to achieve final dimensional tolerances.
