Value Collection 723-6426 Corner Rounding End Mill

Product Description

The VALUE COLLECTION 723-6426 is a single-end corner rounding end mill designed to machine consistent radii on workpiece edges. Built from M42 cobalt high-speed steel, it delivers reliable performance in ferrous materials and harder alloys where standard HSS tooling wears prematurely. The cutter features a 1/8-inch radius and a 5/8-inch mill diameter with 4 right-hand flutes. The bright/uncoated finish is suitable for a broad range of general machining applications. Machinists, toolmakers, and CNC operators install this end mill in vertical mills, CNC machining centers, and manual knee mills for edge-breaking and radius profiling operations.

This corner rounding end mill is suited for use in production and job-shop environments where edge-radius consistency is required. It performs edge contouring on steel, stainless, and alloy materials. The 3/8-inch shank diameter accommodates standard end mill holders and collet chucks commonly found on knee mills and CNC vertical machining centers. The 3-inch overall length provides adequate reach for most standard depth-of-cut requirements without excessive overhang.

Key Features

• M42 cobalt HSS construction for improved heat and wear resistance compared to standard M2 HSS
• 1/8-inch corner radius for consistent, repeatable edge profiling
• 4 right-hand flutes with right-hand cutting direction for standard milling spindle compatibility
• Bright/uncoated finish suitable for use with cutting fluids across a range of ferrous materials
• Single-end design with 3/8-inch shank diameter for use in standard collet chucks and end mill holders
• 3-inch overall length minimizes overhang while providing workable reach

Compatibility

Designed as an OEM-style replacement or direct-use corner rounding end mill for vertical mills and CNC machining centers accepting a 3/8-inch shank end mill holder or collet.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 3/8-inch shank fully into the collet or end mill holder and torque the retention hardware per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning the cut, and apply appropriate cutting fluid for the workpiece material.
