Value Collection 723-6687 Corner Rounding End Mill Set 8 Pc

Product Description

The VALUE COLLECTION 723-6687 is an 8-piece corner rounding end mill set machined from M42 cobalt high-speed steel. Each cutter features a 4-flute, single-end geometry with a bright uncoated finish, making the set well suited for edge-profiling and corner-rounding operations on steel, stainless, cast iron, and other ferrous materials. The set ships in a wood stand that keeps each cutter indexed and ready at the machine. Mill diameters span 1/16 inch through 3/8 inch in fractional increments, covering a broad range of radius profiles without requiring a separate order for individual tools.

This set is used in job shops, tool rooms, and production environments where machinists need consistent corner radii on milled parts. The cobalt M42 substrate tolerates higher cutting temperatures than standard M2 HSS, extending tool life in tougher alloys. The single-end configuration is standard for manual mills and CNC machining centers running corner-rounding routines on workpiece edges. The wood stand makes the set practical for bench storage near a knee mill or vertical machining center.

Key Features

• M42 cobalt HSS substrate for elevated heat and wear resistance
• 4-flute geometry provides smooth finish on corner-rounding passes
• 8-piece set covers mill diameters: 1/16, 3/32, 1/8, 5/32, 3/16, 1/4, 5/16, and 3/8 inches
• Bright uncoated finish — no coating to chip or delaminate on regrind
• Single-end design compatible with standard end mill holders and collet chucks
• Includes wood stand for organized bench or toolbox storage

Compatibility

Designed for use in standard end mill holders, collet chucks, and milling arbors sized to match each cutter shank diameter across the set. Suitable for manual knee mills and CNC vertical machining centers performing corner-rounding operations.

Installation Notes

Installation is performed by a machinist or toolroom professional. Secure each cutter in a properly sized collet or end mill holder and torque to the holder manufacturer's specification before cutting. Inspect shank and collet bore for chips or burrs before seating any cutter. Always power down the spindle and engage the E-stop before changing tools.
