Value Collection 723-6777 Roughing End Mill 13/16 in Cobalt

Product Description

The VALUE COLLECTION 723-6777 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 extended tool life in demanding cutting applications. The 13/16 inch (0.8125 inch) cutting diameter pairs with a 1-7/8 inch length of cut and a 3/4 inch shank, making it well-suited for roughing passes on steel, stainless, and other ferrous materials. With 4 flutes and right-hand cutting and flute direction, it is a standard configuration recognized by machinists across job shop and production environments.

This end mill is used in vertical machining centers, knee mills, and manual milling machines where high-stock-removal roughing cuts are required. The cobalt M42 substrate handles elevated cutting temperatures better than standard M2 high-speed steel, which is useful when cutting harder alloys or when coolant is limited. The non-centercutting design means it is intended for peripheral and side milling passes, not plunge entry. It is installed by machinists, toolroom operators, and CNC setup technicians.

Key Features

• M42 cobalt high-speed steel construction for improved heat and wear resistance over standard HSS
• TiN coating reduces friction and extends cutting edge life
• 13/16 inch (0.8125 inch) mill diameter with 3/4 inch shank for secure tool holding
• 1-7/8 inch length of cut suited for moderate-depth roughing passes
• 4-flute, right-hand cut and right-hand helix geometry
• Single-end design with non-centercutting tip — peripheral and side milling use only

Compatibility

Designed as a standard-shank roughing end mill compatible with 3/4 inch collets, end mill holders, and milling chucks used in conventional and CNC milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill. Seat the shank fully into the holder to the recommended minimum engagement depth per the tool holder manufacturer. Because this is a non-centercutting end mill, do not use it for direct plunge cuts — ramp or helical entry strategies are required when full-depth slot entry is needed.
