Value Collection 723-6477 Corner Rounding End Mill

Product Description

The VALUE COLLECTION 723-6477 is a single-end corner rounding end mill designed for machining radius edges on ferrous and non-ferrous workpieces. Built from M42 cobalt high-speed steel, it delivers strong heat and wear resistance in demanding cutting applications. The mill features a 1-1/8 inch diameter, a 9/32 inch corner radius, and a 1/2 inch shank diameter. With 4 right-hand flutes and a bright, uncoated finish, it suits general-purpose rounding and profiling operations on mills and machining centers. It is sold as a single unit and is a practical choice for toolroom, production, and maintenance machining tasks.

This corner rounding end mill is suited for use on manual mills and CNC machining centers where a consistent edge radius is required. It is commonly used in metal fabrication shops, toolrooms, and production environments working with steel, stainless steel, and similar materials. The M42 cobalt substrate makes it a capable option where elevated cutting temperatures are a factor, such as in interrupted cuts or harder alloy steels. Licensed machinists and tool-and-die technicians are the typical end users.

Key Features

• M42 cobalt construction for improved heat and wear resistance over standard HSS
• 9/32 inch corner radius for consistent edge profiling
• 4 right-hand flutes with right-hand cutting direction for standard spindle use
• Bright, uncoated finish suitable for a wide range of general machining applications
• Single-end design with 1/2 inch shank for secure toolholder engagement

Compatibility

Designed as a standard single-end corner rounding end mill with a 1/2 inch shank, compatible with toolholders and collet chucks sized for 1/2 inch shank tooling on manual or CNC milling machines.

Installation Notes

Installation should be performed by a qualified machinist familiar with end mill toolholding practices. Ensure the machine spindle is fully stopped and the power is locked out before inserting or removing the tool from its holder. Seat the shank fully into a properly sized collet or end mill holder and torque the retention hardware per the toolholder manufacturer's specifications. Verify runout after installation before beginning a cut.
