Value Collection 724-1191 Roughing End Mill 3/4 in Cobalt

Product Description

The VALUE COLLECTION 724-1191 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a TiN coating, it delivers heat resistance and edge retention in tough ferrous and non-ferrous materials. The 3/4 inch diameter cutter features 4 flutes with a right-hand cutting and flute direction, a 2.5 inch length of cut, and a 4.625 inch overall length. The 3/4 inch straight shank fits standard ER and end mill holders. This tool is installed and operated by machinists and toolroom technicians in CNC and manual milling applications.

The 724-1191 is suited for roughing passes on steel, stainless, and high-temperature alloys in both job shop and production environments. Its center-cutting geometry allows plunge entry as well as conventional peripheral cuts, making it versatile for pocketing, slotting, and profile milling. The TiN coating reduces friction and extends tool life compared to uncoated cobalt tooling. No extended reach geometry is present, keeping the tool rigid for standard-depth applications.

Key Features

• M42 cobalt steel construction for elevated heat and wear resistance
• TiN coating reduces friction and extends cutting edge life
• 4-flute, single-end design optimized for roughing passes
• Center-cutting capable — supports plunge entry
• Right-hand cut and right-hand helix for standard spindle operation
• 3/4 inch shank diameter matches cutter diameter for direct chuck or collet holding

Compatibility

Designed as a standard replacement or stock roughing end mill for milling machines accepting a 3/4 inch straight shank, including CNC machining centers and manual knee mills with compatible collet chucks or end mill holders.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the spindle before inserting or removing the end mill from the holder. Ensure the shank is fully seated and the set screw or collet nut is torqued according to the toolholder manufacturer specifications. Inspect the cutting edges for chipping before each use and replace the tool when edge condition degrades to avoid workpiece damage.
