Value Collection 723-6438 Corner Rounding End Mill

Product Description

The VALUE COLLECTION 723-6438 is a single-end corner rounding end mill designed to mill a consistent radius on workpiece edges and corners. Built from M42 cobalt high-speed steel, it handles harder materials and higher cutting temperatures than standard HSS tooling. The 5/32-inch cutting radius, 3/4-inch mill diameter, and 4-flute geometry work together to produce smooth, repeatable corner profiles on ferrous and non-ferrous metals. The bright, uncoated finish suits shops that prefer to apply their own coatings or work with materials where coated tooling is not required. Machinists and tool-and-die professionals install this mill in standard CNC and manual milling machines.

This end mill is suited for edge-finishing and profiling operations on milling machines in job shops, production facilities, and tool rooms. The 1/2-inch shank diameter fits common R8, ER, and side-lock collet systems found on vertical mills. The 3-inch overall length provides adequate reach for most standard setups without excessive overhang. Right-hand cutting and right-hand flute direction are the conventional configuration for climb and conventional milling on horizontal and vertical knee mills as well as machining centers.

Key Features

• M42 cobalt HSS construction for improved heat and wear resistance over standard M2 tooling
• 5/32-inch corner radius for consistent edge-rounding in a single pass
• 4-flute design balances chip evacuation and surface finish on ferrous materials
• Bright, uncoated finish — compatible with most cutting fluids and coolant systems
• Single-end configuration with right-hand cut and right-hand helix
• 1/2-inch shank fits widely available collet and end-mill holder systems

Compatibility

Designed as a standard replacement or stocking corner rounding end mill for CNC machining centers and manual vertical mills accepting a 1/2-inch shank diameter.

Installation Notes

A licensed machinist or skilled operator should install this tool in a properly rated collet, shrink-fit, or side-lock holder sized for a 1/2-inch shank. Ensure the spindle is fully powered down and locked out before changing tooling. Minimize overhang beyond the holder to reduce chatter and deflection. Inspect the cutting edges for chips or damage before each use and confirm the workpiece is securely fixtured before initiating a cut.
