Value Collection 723-8616 Square End Mill 4mm 4 Flute Cobalt

Product Description

The VALUE COLLECTION 723-8616 is a cobalt square end mill designed for precision milling operations in metal cutting applications. Built from M42 cobalt high-speed steel, this single-end tool features a 4 mm (0.1575 inch) cutting diameter and a 4-flute spiral geometry with a 30-degree helix angle. The right-hand cut and right-hand flute direction deliver efficient chip evacuation and consistent surface finishes. The bright, uncoated finish is well-suited for general-purpose ferrous and non-ferrous machining where coating is not required. Machinists and tool-and-die professionals reach for this tool when close-tolerance slot milling, peripheral milling, and profile work are on the schedule.

This end mill fits standard milling setups requiring a 3/8 inch (0.3750 inch) shank diameter. With a 1/2 inch length of cut and a 2-3/8 inch overall length, it is sized for regular-reach applications in vertical mills, CNC machining centers, and manual knee mills. The centercutting design allows plunge entry, expanding its usefulness for pocket milling and ramp-entry operations. It is a solid choice for job shops, maintenance machining, and production environments where consistent cobalt tooling is needed without specialty coatings.

Key Features

• M42 cobalt construction for heat resistance and extended tool life in tough ferrous materials
• 4-flute spiral geometry with 30-degree helix angle for balanced chip load and smooth cut
• Centercutting design supports direct plunge entry and ramp milling
• Right-hand cut and right-hand flute direction for standard milling setups
• Bright, uncoated finish suitable for general-purpose applications
• Single-end configuration with regular length for rigid, accurate cuts

Compatibility

Designed as a standard-shank replacement cobalt square end mill for milling machines and CNC machining centers that accept a 3/8 inch shank diameter toolholder.

Installation Notes

Installation is performed by qualified machinists. Secure the shank fully into a clean, properly sized collet or end mill holder before tightening to the spindle manufacturer's recommended procedure. Verify spindle direction matches the right-hand cutting orientation before engaging the workpiece. Inspect the cutting edges for chips or damage prior to each use, and never exceed the tool's rated depth of cut or feed rate for the workpiece material.
