Value Collection 723-5786 Roughing End Mill 7/8 in 5 Flute Cobalt

Product Description

The VALUE COLLECTION 723-5786 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a bright, uncoated finish, this tool handles tough ferrous and non-ferrous materials where heat resistance and edge retention matter. The 7/8 inch (0.875 inch) cutting diameter pairs with a 1.125 inch length of cut and a 3-3/8 inch overall length. Five flutes deliver efficient chip evacuation and a smooth surface finish relative to standard roughing geometry. Right-hand cutting and right-hand flute direction are standard for conventional milling setups. This tool is installed and used by machinists and tool-and-die professionals on manual mills and CNC machining centers.

This roughing end mill is suited for slot milling, peripheral milling, and stock removal passes in shop and production environments. The 7/8 inch shank diameter matches the cutting diameter, making it compatible with standard ER collet chucks, Weldon-style end mill holders, and milling machine spindles sized for 7/8 inch tooling. It is not center-cutting, so it is not intended for direct plunge operations. Typical applications include roughing passes on steel, alloy steel, stainless, and similar materials before finish milling.

Key Features

• M42 cobalt HSS construction for elevated heat and wear resistance compared to standard M2 HSS
• 5-flute geometry for higher feed rates and improved surface finish during roughing passes
• Bright, uncoated finish suitable for use with cutting fluids on a broad range of metals
• Right-hand cut and right-hand helix for compatibility with standard milling machine setups
• Single-end design with 7/8 inch shank diameter matching the cutting diameter
• Non-center-cutting — not intended for plunge milling without pre-drilled entry points

Compatibility

Designed as an OEM-style replacement and standard tooling option for milling machines accepting 7/8 inch shank end mill holders, ER collet systems, and Weldon-style tool holders.

Installation Notes

A licensed machinist or qualified shop technician should install and operate this end mill. Ensure the milling machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Verify holder runout and torque set screws or collet nuts to holder manufacturer specifications before cutting. Always apply appropriate cutting fluid for the workpiece material and observe chip evacuation to prevent tool loading during roughing passes.
