Cobalt TiCN Square End Mill

The Cleveland Golf Cobalt TiCN Square End Mill is a general-purpose milling cutter designed for finishing operations. Its cobalt substrate and TiCN coating suit machinists and maintenance teams who need reliable tool life in ferrous and non-ferrous materials.

Verify Shank and Holder Compatibility

Confirm that your tool holder accepts a 3/8 inch shank diameter before ordering. The 30 degree helix angle and right-hand cutting direction require a rigid setup to avoid chatter during finishing passes.

Double-End Design Extends Tool Life

The double-end configuration provides two cutting ends on a single tool body, effectively doubling available cutting edges. TiCN finish reduces friction and heat buildup, helping maintain sharpness across repeated finishing cuts.

Questions about this item

Does the double-ended 1/4-inch mill ship with any holders or collets, or must they be purchased separately?

The mill is supplied as a single cutting tool; tool holders, collets or arbors are not included and must be sourced separately.

When should I choose this 1/4-inch, 4-flute, double-ended version instead of a single-ended or different-diameter option?

Choose this version when you need two cutting ends on one 1/4-inch shank tool for finishing operations in a 3/8-inch holder.

How does the 30-degree helix and TiCN finish affect tool life and surface finish in a CNC machine?

The 30-degree helix and TiCN coating reduce wear and improve chip evacuation, giving longer life and finer finishes on general-purpose milling jobs.
