Value Collection 723-5531 Roughing End Mill 0.75 in Cobalt

Product Description

The VALUE COLLECTION 723-5531 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel with a bright, uncoated finish, this tool handles tough ferrous and non-ferrous materials where standard HSS tooling may wear prematurely. The 0.75-inch diameter, 4-flute coarse-pitch geometry breaks chips aggressively, reducing cutting forces and heat buildup during heavy stock removal passes. With a 1.75-inch length of cut and 4-inch overall length, it fits standard end mill holders and is installed by machinists and tool-and-die professionals on vertical and horizontal milling machines.

This roughing end mill is suited to job shop, production, and maintenance machining environments where high metal removal rates are the priority before a finish pass. The coarse pitch flute design minimizes chatter on harder materials including alloy steels and stainless. The right-hand cutting and right-hand flute direction make it compatible with conventional CNC and manual milling setups. It is not center-cutting, so it requires a pre-drilled entry point or side entry for plunge operations.

Key Features

• M42 cobalt construction for extended tool life in harder workpiece materials
• Coarse-pitch, 4-flute geometry for aggressive chip breaking and high stock removal
• 0.75-inch shank diameter matches mill diameter for rigid, direct holder fitment
• Bright, uncoated finish maintains dimensional accuracy without coating thickness variation
• Right-hand cut and right-hand helix compatible with standard milling spindle rotation
• Not center-cutting — requires side entry or pre-drilled starting point for plunge moves

Compatibility

Designed as a standard single-end roughing end mill for use in 0.75-inch end mill holders on conventional and CNC milling machines. No specific machine or system compatibility data was provided by the manufacturer for this part number.

Installation Notes

Installation is performed by a machinist or tooling technician. Secure the 0.75-inch shank in a properly sized collet or end mill holder and torque the holder to the machine spindle per the machine tool manufacturer's specifications. Ensure the spindle is fully stopped and locked before tooling changes. Verify run-out with a dial indicator after mounting to confirm proper seating before engaging a cut.
