Cleveland C81029 0.25 in Carbide Square End Mill

Cleveland C81029 Carbide End Mill

The Cleveland C81029 is a solid carbide square end mill designed for general-purpose milling in a workshop or light-production environment. Its 0.25 in cutting diameter and 1.125 in length of cut suit slotting, profiling and facing operations on ferrous and non-ferrous materials. The TiAlN coating adds heat resistance for extended tool life. Machinists seeking a reliable single-end cutter for CNC or manual mills will find it fits standard 1/4 in tool holders.

Fits standard 1/4 in shank tooling

The straight 1/4 in shank seats directly into ER collets, Weldon flats or shrink-fit holders without adapters, freeing the spindle for quick tool changes. No coolant-through channels are present, so external flood or mist coolant must be supplied by the machine. The 3 in overall length clears most vise jaws and fixture clamps while keeping overhang short for rigidity. Builders needing through-spindle coolant or a reduced neck for deep cavities must select a different tool.

TiAlN coating handles sustained heat

Under continuous cutting the TiAlN layer resists oxidation at higher temperatures than uncoated carbide, allowing consistent feeds without rapid flank wear. The two-flute geometry evacuates chips efficiently in slotting, though chip packing can occur in deep pockets if feed rates are not managed. The tool has no internal coolant passage, so thermal shock is avoided by maintaining steady external coolant flow during long runs.
