Value Collection 723-8622 Square End Mill 5mm 4-flute Cobalt

Product Description

The VALUE COLLECTION 723-8622 is a cobalt square end mill designed for milling operations that demand durability and resistance to heat. Built from M42 cobalt high-speed steel, this single-end tool features a 5 mm (0.1969 inch) cutting diameter and a 9/16 inch (0.5625 inch) length of cut. The 4-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and a smooth finish on ferrous and hard materials. Machinists and tool-and-die professionals use this end mill in vertical mills, CNC machining centers, and manual knee mills.

This end mill is suited for general-purpose slot milling, profiling, and peripheral milling in ferrous metals, stainless steel, and high-temperature alloys where cobalt tooling is preferred over standard HSS. The regular-length geometry and 3/8 inch shank diameter make it compatible with standard ER collet chucks, Weldon-style holders, and end mill adapters commonly found in job shops and production environments. The centercutting design allows plunge entry without a pilot hole.

Key Features

• M42 cobalt construction for improved heat and wear resistance over standard HSS
• 4-flute spiral design with 30-degree right-hand helix for efficient chip removal
• Centercutting geometry allows direct plunge milling
• Bright/uncoated finish suitable for use with or without cutting fluid
• Single-end configuration with 3/8 inch shank for standard toolholder compatibility
• Regular-length body for rigidity in typical depth-of-cut applications

Compatibility

Designed as a general-purpose replacement or production end mill for use in standard ER collet chucks and end mill holders accepting a 3/8 inch shank diameter.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool is seated securely in the holder before tightening. Verify runout with a dial indicator after setup, as excessive runout will accelerate tool wear and reduce surface finish quality. Do not exceed the recommended depth of cut for the cutter diameter and workpiece material.
