Cobalt Square End Mill for Finishing

This Cleveland Golf end mill is a general-purpose cutting tool designed for finishing operations in a machine shop. The two-flute, single-end geometry suits machinists who need a reliable cobalt cutter for profiling and slotting tasks. It arrives new and ready for use in milling machines equipped for right-hand cutting.

TiCN Coating and 30-Degree Helix

The TiCN finish reduces friction and improves wear resistance compared with uncoated cobalt, extending tool life in steel and alloy work. A 30-degree helix angle promotes smooth chip evacuation and a stable cut during finishing passes. The corner radius measures .000 inches for a true square profile.

Half-Inch Shank Matches Cutter Diameter

The 1/2-inch shank diameter matches the milling diameter, allowing direct clamping in a standard collet or end-mill holder without a reducing sleeve. The 1-inch length of cut and 3-1/4-inch overall length provide reach for shallow cavities while keeping the setup rigid. Builders needing longer reach or a different corner radius will need a separate tool.

Questions about this item

What does the 30-degree helix angle mean when the tool is cutting?

The 30-degree helix provides a balanced chip evacuation and cutting smoothness for general-purpose finishing in a variety of materials.

How does the TiCN finish affect the tool's operating limits?

The TiCN coating increases surface hardness and heat resistance, allowing higher cutting speeds and longer tool life compared to uncoated cobalt.

What holder or collet size is required for the 1/2-inch shank?

A standard 1/2-inch collet, end mill holder, or shrink-fit holder matching the shank diameter is needed for secure mounting.
