Square End Mill for Finishing Operations

This 5/16 inch high-speed steel end mill features four flutes and a 3/4 inch length of cut. The single-end design with a 3/8 inch shank suits general-purpose finishing in a milling machine. Bright uncoated finish and 30 degree helix angle support chip evacuation in steel and non-ferrous materials.

Verify Machine and Holder Compatibility

Confirm your milling machine accepts a 3/8 inch shank and provides enough clearance for the 2-1/2 inch overall length. The right-hand cutting direction requires standard spindle rotation. Ensure the workpiece and fixturing are rigid enough for finishing passes with a four-flute tool.

Replaces Worn or Undersized Finishing Cutters

Upgrade from a dull or smaller-diameter end mill when surface finish quality drops or tolerances widen. The jump is worth it when a fresh 5/16 inch four-flute geometry restores finish consistency without changing toolpaths. Buyers needing roughing capability or larger material removal rates should select a different tool style.

Questions about this item

Does the Cleveland Golf end mill come with a holder or collet, or do I need to buy one separately?

The tool is supplied as a single square end mill only; a compatible 3/8 in. shank holder or collet must be purchased separately.

Should I choose the 5/16 in. diameter version or a different size for finishing work?

This listing is for the 5/16 in. diameter, four-flute, single-end mill with a 3/4 in. length of cut — select it when that exact cutting diameter and flute count match your finishing operation.

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

The 30-degree right-hand helix on this high-speed steel cutter provides standard chip flow for general-purpose finishing in steel and similar materials.
