Value Collection 723-6480 Corner Rounding End Mill Cobalt

Product Description

The VALUE COLLECTION 723-6480 is a single-end corner rounding end mill designed to cut precise convex radii on workpiece edges. Built from M42 cobalt high-speed steel, it handles tough ferrous and stainless alloys where standard HSS tools lose edge integrity. The cutter measures 1.125 inches in diameter with a 9/32-inch radius and runs a 3/4-inch straight shank. Four right-hand flutes with a bright, uncoated finish make it a solid choice for machining operations where recutting chips is a concern. Machinists, tool-and-die makers, and CNC operators install this type of cutter in vertical or horizontal milling machines and machining centers.

Corner rounding end mills like the 723-6480 are used in job shops, tool rooms, and production environments to apply consistent edge radii on mold components, structural parts, dies, and fixtures. The 9/32-inch radius is well-suited for medium to large workpieces where a pronounced, smooth corner break is required. The right-hand cutting direction is standard for conventional milling setups. This is a single-end tool, meaning it is replaced rather than flipped when the cutting edge wears.

Key Features

• M42 cobalt HSS construction provides elevated heat and wear resistance compared to standard M2 HSS
• 9/32-inch corner radius produces a consistent convex edge profile in a single pass
• 1.125-inch mill diameter with a 3/4-inch shank for rigid tool holding in standard collets and end mill holders
• Four right-hand flutes with bright, uncoated finish suited for ferrous and general-purpose milling
• Single-end design for straightforward replacement without refixturing
• Right-hand cutting and flute direction matches conventional milling machine spindle rotation

Compatibility

Designed as a standard replacement or stock cutter for milling machines and machining centers that accept a 3/4-inch shank end mill holder or collet chuck.

Installation Notes

Installation is performed by a machinist or toolroom professional. Power down and lock out the spindle before loading or removing the cutter from the holder. Seat the shank fully in the collet or end mill holder and torque the retention hardware according to the machine tool or toolholder manufacturer guidelines. Verify spindle rotation direction matches the right-hand cutting direction of this tool before engaging the workpiece.
