Value Collection 723-8703 Square End Mill 4 Flute Cobalt

Product Description

The VALUE COLLECTION 723-8703 is a cobalt square end mill designed for milling operations requiring durability and heat resistance beyond standard high-speed steel tooling. Built from M42 cobalt material, this single-end mill features four spiral flutes with a 30-degree helix angle and a bright uncoated finish. It is center-cutting, allowing plunge entry into workpieces, and runs in a right-hand cut with right-hand flute direction. The regular-length geometry suits general-purpose face milling, slotting, and peripheral milling across a range of ferrous and non-ferrous materials. This tool is used by machinists and toolroom operators in job shop and production environments.

This end mill fits standard milling machines, CNC machining centers, and manual knee mills accepting a 0.75 inch shank. The 0.8661 inch cutting diameter and 1.875 inch length of cut make it suited for moderate-depth slotting and profiling passes. The cobalt construction handles elevated cutting temperatures, making it a practical choice for harder steels and stainless where uncoated HSS wears prematurely. No coolant-through capability is present, so flood or mist coolant applied externally is the standard approach for heat management during extended cuts.

Key Features

• M42 cobalt construction for improved heat and wear resistance over standard HSS
• Four spiral flutes with 30-degree helix angle for efficient chip evacuation
• Center-cutting design allows direct plunge milling without a pre-drilled entry hole
• Bright uncoated finish suitable for a wide range of general milling applications
• Right-hand cut and right-hand flute direction for standard spindle operation
• Single-end configuration with regular length for rigid tool overhang

Compatibility

Designed as a standard shank end mill compatible with milling machine tool holders, collet chucks, and end mill holders accepting a 0.75 inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Power down and lock out the machine spindle before loading or removing the end mill from the tool holder. Ensure the shank is fully seated and the set screw or collet is torqued to the tool holder manufacturer's specification. Inspect the cutting edges for chips or damage before use and confirm correct spindle direction matches the right-hand cut orientation of this tool.
