Value Collection 723-5761 Roughing End Mill 0.75 in 4 Flute Cobalt

Product Description

The VALUE COLLECTION 723-5761 is a single-end roughing end mill designed for high-speed material removal in ferrous and non-ferrous metals. Built from M42 cobalt high-speed steel with a bright, uncoated finish, it delivers the heat resistance and edge retention needed for aggressive roughing passes. The 0.75-inch cutting diameter and 1.625-inch length of cut make it well suited for slotting, side milling, and profile roughing in a standard knee mill or CNC machining center. Four right-hand flutes with a right-hand cutting direction provide efficient chip evacuation during heavy cuts. This tool is installed and used by machinists and toolroom technicians working in job shops, production machining, and maintenance environments.

This roughing end mill is a practical choice for roughing operations on steel, alloy steel, stainless steel, and similar materials where a cobalt tool grade provides an advantage over standard HSS. The 0.625-inch shank diameter fits standard ER or side-lock toolholders common in both manual and CNC setups. The non-centercutting geometry means this tool is not intended for plunge milling entry cuts. It is suited for ramping or side-entry approaches where roughing stock removal is the primary goal before a finishing pass.

Key Features

• M42 cobalt steel construction for improved heat and wear resistance over standard HSS
• 0.75-inch mill diameter with 1.625-inch length of cut for substantial material removal
• 4-flute, right-hand spiral geometry promotes efficient chip evacuation in roughing cuts
• Bright, uncoated finish suitable for use with cutting fluids on a broad range of metals
• Single-end design with 0.625-inch shank for compatibility with standard toolholders
• Non-centercutting geometry requires ramp or side entry rather than direct plunge

Compatibility

Designed as a direct-fit roughing end mill for standard 0.625-inch I.D. end mill toolholders used in manual knee mills and CNC machining centers requiring a 3/4-inch diameter cobalt rougher.

Installation Notes

Installation is performed by machinists or toolroom technicians. Secure the shank fully into a clean, properly torqued collet or side-lock holder before use. Ensure spindle speed and feed rate are set appropriately for the workpiece material and machine rigidity before engaging the cut. Inspect the cutting edges for chipping or wear before each use and do not continue operation with a damaged tool.
