Square-end cobalt mill for finishing

This double-ended cobalt square-end mill is built for general-purpose finishing work. The 3/8-inch shank and 30-degree helix angle suit standard milling setups. Bright uncoated surfaces reduce cost for routine tasks. Right-hand cutting direction matches common machine rotations.

Suited to finishing passes on softer metals

Machinists running finishing cuts on aluminium, brass or mild steel will find the two-flute geometry effective. It is not for heavy roughing where chip evacuation demands more flutes. Builders needing coated tools for abrasive alloys should look elsewhere. Users requiring a corner radius must choose a different cutter.

3/8-inch fractional diameter decides fit

The 3/8-inch milling diameter and matching shank diameter lock this tool into holders and collets sized for that dimension. Overall length of 3-1/2 inches and 9/16-inch length of cut define reach and depth limits. Verify holder capacity and workpiece clearance before ordering.
