Cleveland Golf Cobalt 3/16" 4 Flute Double Square End Mill

Cobalt square end mill for finishing

This 3/16 inch diameter cobalt end mill is built for general-purpose finishing in ferrous and non-ferrous materials. Its four-flute design and right-hand helix suit machinists and maintenance shops that need clean profiles and square corners. The bright uncoated finish keeps the tool affordable for routine production and one-off repair work.

7/16 inch length of cut with double-ended value

Each tool provides two usable ends, effectively doubling the cutting edges per purchase. The 7/16 inch flute length handles shallow pockets, slots and perimeter passes, while the 3/8 inch shank fits standard ER collets and Weldon holders. Once both ends wear, the cutter is replaced rather than re-sharpened.

30-degree helix balances chip flow and rigidity

The 30-degree helix angle moves chips away from the cut without excessive vibration in typical finishing passes. Cobalt substrate resists heat buildup better than high-speed steel, extending tool life in abrasive alloys. Uncoated surfaces run cooler than coated alternatives when speeds are conservative and flood coolant is used.
