Cleveland C61831 4-Flute Carbide Square End Mill .1875 in

3/16 in Shank Carbide End Mill

This 3/16 in shank carbide square end mill is designed for general-purpose milling in a variety of materials. It suits machinists and maintenance technicians who need a reliable cutter for slotting, profiling and plunge operations. The uncoated carbide substrate provides good wear resistance at a lower cost than coated alternatives. It is not intended for high-volume production runs that demand specialised coatings or geometries.

0.1875 in Diameter Cutting Capacity

The 0.1875 in milling diameter with a 0.3125 in length of cut handles light to medium material removal in a single pass. The 2 in overall length provides adequate reach for shallow pockets and through-slots without excessive overhang. Rigidity decreases as axial depth approaches the length of cut limit, so heavier cuts should be broken into multiple passes. Deep cavities or long-reach profiling exceed the tool's effective range.

4-Flute Uncoated Carbide Construction

Four flutes deliver a finer surface finish and higher feed rates than two- or three-flute tools in materials that produce manageable chips. The uncoated carbide grade performs well in cast iron, non-ferrous alloys and abrasive plastics where coating adhesion is less critical. It lacks the heat resistance of AlTiN or TiAlN coatings for sustained high-speed steel machining. Buyers cutting hardened steels or running high-temperature alloys should select a coated alternative.
