Value Collection 724-4140 Roughing Finishing End Mill

Product Description

The VALUE COLLECTION 724-4140 is a single-end roughing finishing end mill designed for metal removal and surface finishing in a single tool. Built from M42 cobalt high-speed steel, it handles tough ferrous materials and maintains cutting performance under heat. The mill measures 5/8 inches in diameter with a 3/4 inch length of cut and a 4-flute, square-end geometry. A 30-degree helix angle and right-hand flute direction support efficient chip evacuation during milling passes. The bright/uncoated finish leaves the base material exposed for applications where coating adhesion or heat buildup would be a concern.

This end mill is suited for general-purpose milling operations in job shop, tool room, and production environments. The Weldon flat shank provides positive drive engagement in standard end mill holders and reduces pullout risk under lateral cutting loads. With a 5/8 inch shank diameter and 2-7/8 inch overall length, it fits conventional milling machines, machining centers, and knee mills. Typical applications include profiling, slotting, and step milling in steel, stainless, and similar alloys. Non-centercutting geometry means this tool is not intended for plunge entry.

Key Features

• M42 cobalt HSS construction for elevated heat and wear resistance
• 4-flute square end geometry for profiling and finishing passes
• 30-degree helix angle promotes chip flow and reduces cutting pressure
• Weldon flat shank for positive drive in standard end mill holders
• Bright/uncoated finish suitable for dry or lubricated cutting
• Single-end design; right-hand cut and right-hand flute direction

Compatibility

Designed as a direct-fit replacement for standard 5/8 inch shank end mill holders used in conventional milling machines and CNC machining centers requiring a single-end cobalt roughing finishing end mill.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the Weldon flat against the set screw in the holder before tightening; confirm shank engagement meets the holder manufacturer minimum insertion depth. Power down and lock out the spindle before changing tooling. Do not use this tool for plunge cutting, as the non-centercutting geometry is not rated for axial entry.
