Value Collection 723-3663 Square End Mill 1/4 in 3 Flute Cobalt

Product Description

The VALUE COLLECTION 723-3663 is a cobalt square end mill designed for precision milling operations in metal and alloy workpieces. Built from M42 cobalt high-speed steel, it delivers strong heat and wear resistance during aggressive cuts. The tool features a 1/4 inch cutting diameter, a 5/8 inch length of cut, and a 1-3/4 inch overall length. With three spiral flutes and a 30-degree helix angle, it generates efficient chip evacuation and smooth surface finishes. The bright/uncoated finish suits general-purpose applications where coating is not required. This end mill is installed by machinists and tool-and-die professionals in manual and CNC milling setups.

This end mill is suited for milling slots, pockets, and profiles in ferrous and non-ferrous materials. The single-end configuration and 1/4 inch shank diameter make it compatible with standard collet chucks and end mill holders on vertical and horizontal milling machines. The long length type provides added reach for deeper feature work where a standard-length tool may not access the full cut depth. It is appropriate for job shops, maintenance machining, and production environments requiring a reliable cobalt tooling option at a fractional inch standard size.

Key Features

• M42 cobalt construction for elevated heat resistance and tool life in hard materials
• Three spiral flutes with 30-degree helix angle for efficient chip removal
• Center-cutting design allows plunge entry into workpiece
• Right-hand cut and right-hand flute direction for standard spindle operation
• Bright/uncoated finish suitable for general-purpose and coolant-assisted milling
• Single-end configuration with uniform 1/4 inch shank and cutting diameter

Compatibility

Designed as a general-purpose replacement or production end mill for use with standard 1/4 inch collet chucks and end mill holders on vertical milling machines and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist with the spindle fully powered off and the machine in a locked-out state before tooling changes. Secure the shank to the full recommended engagement depth in the collet or holder to prevent runout and pullout during cutting. Verify spindle speed and feed rate are appropriate for the workpiece material and cutting diameter before operation. Do not exceed the tool's rated cutting diameter when selecting radial depth of cut.
