Value Collection 723-8677 Square End Mill 14mm 4 Flute Cobalt

Product Description

The VALUE COLLECTION 723-8677 is a cobalt square end mill designed for milling operations requiring durability and heat resistance. Built from M42 cobalt high-speed steel, this single-end tool features four spiral flutes with a 30-degree helix angle, producing efficient chip evacuation and smooth cutting action. It measures 14 mm (0.5512 inches) in cutting diameter with a 1-3/8 inch length of cut, a 1/2 inch shank diameter, and a 3-3/8 inch overall length. The bright uncoated finish suits applications where coating adhesion to the workpiece is a concern. Center-cutting geometry allows plunge entry as well as standard peripheral milling.

This end mill is suited for general-purpose milling on manual and CNC machining centers. The cobalt M42 grade offers improved red hardness over standard M2 HSS, making it appropriate for harder ferrous materials, stainless steels, and difficult-to-machine alloys at moderate cutting speeds. The regular-length profile fits standard tool holders and collet systems using a 1/2 inch bore. Right-hand cutting and right-hand flute direction are standard configurations compatible with conventional machining setups.

Key Features

• M42 cobalt construction provides enhanced heat and wear resistance versus standard HSS
• Four spiral flutes with 30-degree helix angle for efficient chip removal
• Center-cutting design allows direct plunge milling
• Bright/uncoated finish suitable for a wide range of ferrous and non-ferrous materials
• Right-hand cut, right-hand flute, single-end configuration
• 1/2 inch shank diameter fits common collet chucks and end mill holders

Compatibility

Designed as a general-purpose replacement or stocking end mill for manual mills and CNC machining centers equipped with 1/2 inch collet or end mill holder systems.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the spindle is fully stopped and locked out before mounting or removing the tool. Seat the shank fully into the holder to the recommended engagement depth and torque the set screw or collet nut per the holder manufacturer specifications. Verify runout with a dial indicator before committing to a production cut.
