Cleveland C80558 Carbide End Mill .5 in .625 in cut length

Cleveland C80558 Carbide End Mill

The Cleveland C80558 is a solid carbide square end mill designed for general milling tasks in a workshop setting. Its half-inch cutting diameter and five-flute geometry suit machinists who need a reliable tool for profiling and slotting operations. The TiAlN coating adds heat resistance for longer edge life when cutting steels and other ferrous alloys. This cutter is not intended for applications requiring coolant-through delivery or specialised high-feed roughing strategies.

Thermals noise and power draw

As a rotary cutting tool the end mill generates heat at the shear zone during material removal and the TiAlN coating helps dissipate that heat to protect the carbide substrate. Noise and vibration levels depend on the machine spindle rigidity, work-holding security and the chosen speeds and feeds rather than on the cutter itself. Power consumption is determined by the machine tool and the depth of cut selected by the operator. The non-coolant-through design means external flood or mist coolant must be supplied separately if the operation demands it.

Build quality and connectors

The cutter uses a straight half-inch shank that fits standard ER collets, Weldon flats or shrink-fit holders without adapters. Overall length is two and one-half inches with a length of cut of 0.625 inches providing adequate reach for shallow pockets and face milling. Carbide construction delivers high stiffness and wear resistance compared with high-speed steel alternatives. The absence of a reduced neck limits clearance in deep cavities so the tool is best suited to parts with open access.
