Value Collection 723-2512 Cobalt Square End Mill Set 12 Pc

Product Description

The VALUE COLLECTION 723-2512 is a 12-piece cobalt square end mill set designed for single-end milling operations across a range of common cutting diameters. Built from M42 cobalt high-speed steel, these end mills deliver increased heat resistance and wear durability compared to standard M2 HSS tooling, making them well-suited for harder workpiece materials and extended production runs. The bright, uncoated finish is a practical choice for general-purpose milling where a specific coating is not required. The set ships in a wood stand that keeps each mill organized and protected at the bench or machine side. Licensed machinists and tool-and-die professionals are the primary installers and operators.

This set covers six mill diameters — 1/8 inch, 3/16 inch, 1/4 inch, 5/16 inch, 3/8 inch, and 1/2 inch — all on a 3/8-inch shank. That shared shank diameter allows the entire set to run from a single collet or chuck setup on most vertical milling machines, knee mills, and CNC machining centers configured for 3/8-inch tooling. The set is appropriate for shop environments performing facing, slotting, profiling, and contouring work on a variety of materials where a bright finish is acceptable.

Key Features

• M42 cobalt HSS construction provides higher red hardness than standard M2 tooling
• Six cutting diameters: 1/8, 3/16, 1/4, 5/16, 3/8, and 1/2 inch
• Uniform 3/8-inch shank across all 12 pieces simplifies collet and chuck changes
• Square end geometry suits flat-bottom slotting, profiling, and shoulder milling
• Bright, uncoated finish for general-purpose use without coating-compatibility concerns
• Includes a wood stand for organized bench storage and tool protection

Compatibility

Designed for use in vertical milling machines, knee mills, and CNC machining centers that accept a 3/8-inch shank end mill via collet, end mill holder, or compatible chuck system.

Installation Notes

End mills must be installed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerance. Always power down and lock out the spindle before changing tooling. Verify collet or holder condition and confirm shank seating depth before beginning a cut. Do not exceed the machine spindle speed and feed recommendations for the specific workpiece material and mill diameter in use.
