Cleveland Golf Cobalt End Mill 1/8 4 Flute Double Square End CC

Cleveland Cobalt End Mill 1/8 Inch

This cobalt square end mill has a 1/8 inch milling diameter and four flutes for general-purpose finishing. The double-end design provides two cutting ends on a single 3/8 inch shank. A 30-degree helix angle and right-hand cutting direction suit conventional milling operations. Bright uncoated finish keeps the tool ready for resharpening.

Replaces worn single-end cobalt mills

When a single-end mill dulls, this double-end tool effectively doubles the available cutting length without changing holders. The jump is worth it if your workflow runs frequent finishing passes in steel or exotic alloys and you want fewer tool changes. The 3/8 inch overall length of cut per end matches many standard holder depths. Builders who need roughing geometry or coated performance for high-heat materials should look elsewhere.

Limited by uncoated cobalt substrate

The bright finish offers no thermal barrier, so cutting speeds must stay within cobalt’s uncoated limits to avoid premature wear. A 30-degree helix and zero corner radius restrict chip evacuation in deep slots or heavy radial engagement. The 3-1/16 inch overall length caps reach in deep cavities. Machines without rigid spindles or flood coolant will see reduced tool life.
