Cleveland Golf Cobalt End Mill 5/16 4 Flute Single End CC

Cleveland Cobalt End Mill 5/16

This 5/16 inch cobalt square end mill is a general-purpose cutting tool for milling operations. It features four flutes and a single-end design with a 3/8 inch shank diameter. The bright uncoated finish suits standard machining tasks. Machinists and fabricators use it for finishing work in a variety of materials.

Four-flute geometry limits chip clearance

The 30-degree helix angle and four-flute configuration reduce chip space compared to two-flute tools. This makes deep slotting or heavy roughing less efficient in sticky alloys. The fixed 3/4 inch length of cut restricts reach in deep cavities. Right-hand cutting direction requires standard spindle rotation.

Replaces worn high-speed steel finishing cutters

Upgrading from high-speed steel extends tool life in abrasive or moderately hard materials. The cobalt substrate resists heat better during prolonged finishing passes. The jump is worth it when uncoated HSS tools dull too quickly or chip on tougher stock. It does not suit heavy roughing where chip evacuation is critical.
