Value Collection 723-4104 Square End Mill 3/16 in Cobalt

Product Description

The VALUE COLLECTION 723-4104 is a cobalt square end mill designed for milling operations that demand durability and heat resistance beyond standard high-speed steel tooling. Built from M42 cobalt material, this double-end mill features a 3/16 inch diameter cutting edge with a 1/2 inch length of cut and a 30-degree helix angle. The spiral flute geometry and four-flute configuration promote efficient chip evacuation and a smooth surface finish. The bright uncoated finish makes it straightforward to inspect for wear. Machinists and tool-and-die professionals rely on this style of end mill for profiling, slotting, and peripheral milling on ferrous and harder workpiece materials.

This end mill is suited for use on manual knee mills, CNC machining centers, and tool room equipment where a fractional-inch, right-hand cutting, right-hand helix tool is required. The double-end design provides two usable cutting ends, extending tool life value per piece. With a 3/8 inch shank diameter and 3.25 inch overall length, it fits standard collet chucks and end mill holders commonly found in job shop and production environments. It is center-cutting, allowing plunge entry as well as conventional side milling operations.

Key Features

• M42 cobalt construction for improved heat and wear resistance compared to standard M2 HSS
• Four-flute spiral design promotes chip evacuation and surface finish quality
• 30-degree helix angle balances cutting efficiency and edge strength
• Double-end configuration provides two cutting ends per tool
• Center-cutting geometry allows direct plunge entry into workpiece material
• Bright uncoated finish enables easy visual inspection of cutting edge condition

Compatibility

Designed as an OEM-style replacement or direct substitute for 3/16 inch diameter, 4-flute, cobalt square end mills with a 3/8 inch shank in standard fractional-inch tooling applications.

Installation Notes

Installation is performed by qualified machinists following standard toolholding procedures. Power down and lock out the spindle before inserting or removing the end mill from the collet or end mill holder. Ensure the shank is fully seated and the collet is torqued to the machine manufacturer's specification. Inspect both cutting ends for chipping or wear before each use, and rotate to the second end only when the first shows measurable wear.
