Value Collection 723-2520 Cobalt End Mill Set 20 Pc

Product Description

The VALUE COLLECTION 723-2520 is a 20-piece cobalt end mill set designed for milling operations requiring durable, heat-resistant cutting tools. Each end mill features a square end geometry and is manufactured from M42 cobalt high-speed steel, which provides superior hardness and wear resistance compared to standard HSS tooling. The bright uncoated finish suits general-purpose machining where coating is not required. Diameters range from 3/16 inch to 3/4 inch, giving machinists a broad selection in a single set. The set ships with a wood stand for organized storage at the bench or toolroom.

This set is suited for machine shops, tool rooms, and production environments where a range of end mill sizes is needed without sourcing individual cutters. Each cutter is a single-end configuration, making it appropriate for conventional milling machines, CNC vertical machining centers, and manual knee mills. The M42 cobalt grade performs well in tougher work materials such as stainless steel, cast iron, and high-alloy steels where standard M2 HSS tools fall short. The set is intended for machinists and toolroom technicians working across light to medium-duty milling applications.

Key Features

• M42 cobalt material grade for improved heat and wear resistance over standard HSS
• Square end geometry for shoulder milling, slotting, and profiling operations
• Diameter range of 3/16 inch to 3/4 inch covers common milling tasks in one kit
• Bright uncoated finish suitable for general-purpose and non-ferrous machining
• Single-end construction for use in standard end mill holders and collets
• Includes a wood stand for organized bench-top or toolroom storage

Compatibility

Designed as a general-purpose replacement and replenishment set for standard end mill holders, R8 collets, and ER collet chucks sized to accept 3/16 inch through 3/4 inch shank diameters on conventional and CNC milling machines.

Installation Notes

End mills are installed by a machinist or toolroom technician into a compatible end mill holder or collet chuck. Ensure the machine spindle is fully stopped and the power is locked out before changing tooling. Confirm that the collet or holder bore matches the shank diameter of the selected cutter before tightening. Inspect each cutter for chips or damage before use and discard any cutter showing visible wear or chipping to prevent workpiece damage or tool breakage.
