Value Collection 723-6743 Roughing End Mill 5/8 in Cobalt

Product Description

The VALUE COLLECTION 723-6743 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, this tool handles tough ferrous materials and alloy steels where standard HSS tooling wears quickly. The 5/8-inch diameter, 4-flute design with right-hand cut and right-hand flute direction delivers efficient chip evacuation across the 1.25-inch length of cut. With an overall length of 3.375 inches and a matching 5/8-inch shank, it fits standard collet and end mill holders used in vertical mills and machining centers.

This roughing end mill is suited for roughing passes on ferrous metals, stainless steels, and high-temperature alloys in job shop and production environments. The non-centercutting configuration means it is intended for peripheral and side milling operations rather than plunge cutting. Machinists and tool-and-die professionals use this style of cutter to rapidly remove stock before finishing passes with a standard end mill. It performs on manual knee mills and CNC machining centers alike.

Key Features

• M42 cobalt HSS construction for extended tool life in difficult-to-machine materials
• TiN coating reduces friction and increases surface hardness for longer run times
• 4-flute, right-hand cut geometry optimized for efficient roughing and chip clearance
• Single-end design with 1.25-inch length of cut and 3.375-inch overall length
• 5/8-inch diameter with matching 5/8-inch shank for secure holder engagement
• Non-centercutting — intended for side and peripheral milling, not plunge entry

Compatibility

Designed for use in standard 5/8-inch collet chucks, end mill holders, and milling chucks on vertical knee mills and CNC machining centers performing roughing operations on ferrous and high-temperature alloy workpieces.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered down and at a full stop. Secure the shank fully in the holder to the recommended insertion depth before tightening to avoid runout. Verify spindle direction is set to right-hand rotation before engaging the cut. Do not use this tool for plunge cutting, as it is a non-centercutting design.
