Value Collection 723-5780 Roughing End Mill 7/8 in Cobalt

Product Description

The VALUE COLLECTION 723-5780 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, it measures 0.875 inches in diameter with a 1.125-inch length of cut and a 3.375-inch overall length. The 5-flute configuration promotes faster feed rates and improved chip evacuation compared to standard 4-flute designs. Right-hand cutting and right-hand flute direction are standard. This tool is suited for machinists and tool-and-die professionals working on manual or CNC milling equipment.

This roughing end mill is used in ferrous and non-ferrous metal milling applications where rapid stock removal is the priority. The cobalt M42 construction handles harder workpiece materials and elevated cutting temperatures better than standard HSS tooling. It is a single-end design, meaning it is retired when the cutting end wears, with no option to flip. The 0.75-inch shank diameter fits standard collet chucks and end mill holders common on vertical knee mills and CNC machining centers. It does not feature extended reach or a variable helix geometry.

Key Features

• M42 cobalt high-speed steel construction for improved heat and wear resistance
• 5-flute geometry for higher feed rates and efficient chip removal
• 0.875-inch cutting diameter with 1.125-inch length of cut
• 0.75-inch shank diameter fits standard collet and end mill holders
• Right-hand cut, right-hand flute — compatible with conventional milling setups
• Bright, uncoated finish — suitable for use with cutting fluid

Compatibility

Designed for use in standard milling chucks and collet holders accepting a 0.75-inch shank diameter on manual or CNC vertical milling machines.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out, de-energized state per applicable lockout/tagout procedures. Verify that the collet or end mill holder matches the 0.75-inch shank diameter before tightening. This tool is not centercutting and should not be plunged directly into solid material. Use appropriate cutting fluid for the workpiece material to extend tool life and manage heat.
