Cobalt End Mill for Finishing

This Cleveland Golf cobalt end mill is a double-ended square tool designed for general-purpose finishing work. It has a 5/16 inch milling diameter with four flutes and a 3/8 inch shank. The bright uncoated finish suits conventional milling operations on ferrous and non-ferrous materials.

Check Shank and Holder Compatibility

Verify that your tool holder or collet accepts a 3/8 inch shank before ordering. The fractional inch dimensions and 3/4 inch length of cut require appropriate clearance in your setup. Ensure your machine spindle runs in a right-hand cutting direction to match the tool geometry.

Suited for General-Purpose Finishing

This cutter suits machinists performing finishing passes where a square corner profile is required. The zero corner radius produces sharp internal corners. Buyers needing coated tools for high-speed production or roughing profiles with chip-breaker geometry should look at alternative end mill styles.

Questions about this item

Does the Cleveland Golf end mill come with any holders or collets, or must they be purchased separately?

The tool is supplied as a single double-ended cobalt square end mill with a 3/8 in. shank; holders, collets or tool-changer adapters are not included and must be sourced separately.

When would I choose the 5/16 in. diameter, 4-flute, double-end version instead of a single-end or larger-diameter cutter?

Choose this 5/16 in. double-end mill when you need two fresh cutting ends on one tool, a 3/4 in. length of cut for shallow finishing passes, and a 3/8 in. shank that fits standard holders for smaller pocket work.

What does the 30-degree helix angle mean for chip evacuation and surface finish in steel?

The 30-degree right-hand helix gives a moderate rake that lifts chips steadily in steel while keeping vibration low, helping the four flutes produce a smooth finish on final passes.
