Value Collection 723-9029 Square End Mill 3mm 2 Flute Cobalt

Product Description

The VALUE COLLECTION 723-9029 is a cobalt square end mill designed for metal removal in demanding machining applications. Built from M42 cobalt high-speed steel, it delivers superior heat and wear resistance compared to standard HSS tooling. The cutter features a 3 mm (0.1181 inch) mill diameter, a 5/16 inch (0.3125 inch) length of cut, and a 30-degree helix angle with two right-hand spiral flutes. The bright, uncoated finish suits applications where coating buildup or compatibility with cutting fluids is a concern. This tool is installed by machinists and tool-and-die professionals in manual and CNC milling operations.

This end mill is suited for milling steel, stainless steel, cast iron, and high-temperature alloys — workpiece material codes P, M, K, and S. The single-end, center-cutting design allows plunge entry and is appropriate for slotting, profiling, and peripheral milling passes. With a 3/8 inch shank diameter and a 2-5/16 inch overall length, it fits standard collet chucks and end mill holders commonly found in knee mills and machining centers handling small-diameter toolpaths.

Key Features

• M42 cobalt HSS construction for extended tool life in ferrous and high-temp alloy materials
• 30-degree right-hand helix with 2 spiral flutes for efficient chip evacuation
• Center-cutting geometry allows direct plunge entry without pre-drilling
• Bright/uncoated finish compatible with a wide range of cutting fluids and lubricants
• Single-end design with 3/8 inch straight shank fits standard collet and end mill holders
• Regular length series (VCCC-C-2) for general-purpose milling setups

Compatibility

Designed as a general-purpose replacement or spare for cobalt square end mills with a 3 mm cutting diameter and 3/8 inch shank in standard collet chucks, ER collet systems, and end mill holders accepting straight-shank tooling.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down and lock out the spindle drive before changing tooling. Seat the shank fully into the collet or holder and torque the retaining nut or set screw according to the machine manufacturer's specification. Verify runout with a dial indicator before initiating a cut, particularly on tight-tolerance finish passes.
