Value Collection 723-6733 Roughing End Mill 0.5in 4 Flute Cobalt

Product Description

The VALUE COLLECTION 723-6733 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel and finished with a TiN (titanium nitride) coating, it delivers strong wear resistance and heat tolerance during heavy cuts. The 0.5 inch diameter cutter features 4 right-hand flutes with a right-hand cutting direction, producing a serrated chip-breaking action that reduces cutting forces and heat buildup compared to standard end mills. With a 1.25 inch length of cut and 3.25 inch overall length, it fits standard toolholding setups on vertical and horizontal mills. Licensed machinists and tool-and-die professionals are the primary installers.

This roughing end mill is suited for ferrous and non-ferrous machining applications where rapid stock removal is the priority. It performs in roughing passes on steel, alloy steel, and similar materials before a finishing pass is taken with a separate tool. The 0.5 inch shank diameter fits standard ER collets, side-lock holders, and Weldon-style toolholders commonly found in job shop and production environments. Non-centercutting geometry means it is not designed for plunge entry without a pre-drilled pilot hole or ramped entry path.

Key Features

• M42 cobalt HSS construction for elevated heat and wear resistance
• TiN coating reduces friction and extends tool life on ferrous materials
• 4-flute roughing profile breaks chips and lowers cutting forces
• Right-hand cut, right-hand flute direction for standard spindle rotation
• Single-end design with 0.5 inch diameter shank and 1.25 inch length of cut
• Non-centercutting — requires ramped entry or pre-drilled start hole for plunge operations

Compatibility

Designed as an OEM-style roughing end mill replacement for standard 0.5 inch toolholding systems used in vertical machining centers and manual knee mills.

Installation Notes

Installation is performed by a machinist or toolroom technician. Always power down the spindle and engage the machine lock before changing tooling. Secure the shank fully within the minimum recommended engagement depth of the toolholder to prevent pullout under roughing loads. Verify spindle rotation direction matches the right-hand cutting geometry before initiating a cut.
