Value Collection 723-4526 Roughing End Mill 3/4 in Cobalt

Product Description

The VALUE COLLECTION 723-4526 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, it delivers heat and wear resistance needed for cutting ferrous metals, stainless steels, and other tough alloys. The mill measures 3/4 inch in diameter with a matching 3/4-inch shank diameter, a 3-inch length of cut, and a 5.25-inch overall length. The bright, uncoated finish suits applications where coating adhesion is not required. With three flutes and a high-helix, right-hand cutting geometry, this tool generates efficient chip evacuation and smooth cutting action in roughing passes.

This end mill is suited for use in vertical machining centers, knee mills, and manual milling machines where roughing cuts are performed on steel, cast iron, and other medium-to-hard materials. The center-cutting design allows plunge entry, making it practical for slot milling as well as peripheral roughing. It is a single-end tool, so service life ends when the cutting end is worn. Machinists and tool-and-die professionals working in production or job-shop environments will find this a direct-fit roughing tool for standard 3/4-inch collets and end mill holders.

Key Features

• M42 cobalt steel construction for elevated heat resistance and edge retention in tough alloys
• 3-flute geometry promotes chip clearance during heavy roughing passes
• High-helix flute direction reduces cutting forces and improves surface finish on rough cuts
• Center-cutting capable — supports direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute orientation for standard spindle rotation
• Bright, uncoated finish — ready to use without coating buildup concerns on sticky materials

Compatibility

Designed as a standard 3/4-inch shank roughing end mill compatible with any end mill holder, collet chuck, or milling machine spindle accepting a 3/4-inch straight shank tool.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the machine locked out per standard OSHA lockout/tagout procedures. Secure the shank fully into the holder to the recommended gauge-line depth before tightening. Inspect the collet or holder for wear before seating this tool, as a worn holder can cause runout and premature edge failure. Do not exceed the tool's rated cutting parameters for the workpiece material.
