Value Collection 723-3332 Square End Mill 1-1/4in Cobalt

Product Description

The VALUE COLLECTION 723-3332 is a 6-flute cobalt square end mill engineered for demanding milling operations in ferrous and high-strength materials. Built from M42 cobalt high-speed steel, this long-series tool offers a 1.25-inch mill diameter, a 4-inch length of cut, and a 6.5-inch overall length. The bright, uncoated finish maintains a sharp cutting edge without added coating thickness. A 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. This end mill is a single-end, center-cutting tool, making it suitable for both peripheral and plunge milling in a wide range of machining environments.

This end mill is intended for use in manual knee mills and CNC machining centers where long reach or deep-pocket milling is required. The long-series geometry suits applications where a standard-length end mill cannot reach the full depth of cut. It is commonly applied in job shops, toolrooms, and production environments working with steel, stainless, and other tough alloys. Machinists and CNC operators working with ferrous materials will find the M42 cobalt construction particularly suited to high-heat cutting conditions.

Key Features

• M42 cobalt high-speed steel construction for heat and wear resistance in tough materials
• 6 flutes provide increased feed rates and improved surface finish compared to 4-flute designs
• Long-series length with 4-inch length of cut for deep-pocket and extended-reach applications
• 30-degree right-hand spiral helix for efficient chip evacuation and reduced cutting forces
• Center-cutting design allows direct plunge entry without pre-drilling
• Bright uncoated finish maintains tight dimensional tolerances on the cutting edge

Compatibility

Designed as a general-purpose long-series square end mill compatible with milling machine spindles and CNC machining center tool holders accepting a 1.25-inch shank diameter, including standard ER collet chucks, end mill holders, and Weldon-style side-lock holders.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine powered down and the spindle locked before tool changes. Ensure the shank is fully seated and properly torqued in the tool holder according to the holder manufacturer specifications. Verify runout after installation to avoid premature tool wear or surface finish issues. Consult applicable shop safety standards and machine tool operating procedures before beginning any milling operation.
