Value Collection 723-9002 Cobalt End Mill Set 10 Pc

Product Description

The VALUE COLLECTION 723-9002 is a 10-piece cobalt end mill set covering diameters from 3/16 to 3/4 inches, suited for machining operations that demand durability across a range of cutting sizes. Each cutter is ground to a square end profile with four flutes and a double-end configuration, giving machinists two usable cutting ends per tool. The M42 cobalt steel construction provides elevated heat resistance compared to standard high-speed steel, making this set a practical choice for harder ferrous materials and intermittent heavy cuts. The set arrives uncoated and stored in a wood case for organized access at the bench or in the shop.

This set is appropriate for milling, slotting, and profiling operations on ferrous and non-ferrous metals in job shop, toolroom, and production environments. The range of diameters from 3/16 to 3/4 inches covers common feature sizes encountered in general machining. The double-end design extends usable tool life before a cutter is retired. Machinists working on manual mills, knee mills, and CNC machining centers will find this set useful as a general-purpose kit or a bench backup supply.

Key Features

• M42 cobalt steel construction for improved heat and wear resistance over standard HSS
• Four-flute, square end geometry for profiling, slotting, and side milling
• Double-end design provides two cutting ends per tool, extending usable tool life
• Uncoated finish — compatible with standard cutting fluids without coating compatibility concerns
• Diameter range of 3/16 to 3/4 inches covers a broad spread of common milling sizes
• 10-piece set stored in a wood case for organized tool storage and transport

Compatibility

Designed as a general-purpose replacement and utility set for standard end mill holders and collet chucks sized to accept straight-shank end mills in the 3/16 to 3/4 inch diameter range.

Installation Notes

End mills are installed by a machinist or toolroom technician using a collet chuck or end mill holder rated for the selected diameter. The machine spindle must be fully stopped and the machine powered down before changing tooling. Verify runout with a dial indicator after securing the cutter, and confirm proper shank engagement depth per the holder manufacturer's specification. Double-end cutters should be inspected before flipping to the second end to confirm the used end is not damaged in a way that affects holder grip.
