Cleveland 81066 Carbide End Mill

This Cleveland 81066 square end mill is a carbide cutting tool built for general-purpose milling in a workshop or light-production environment. The .625 inch milling diameter and 5/8 inch shank suit standard tool holders used by machinists and fabricators.

Carbide construction with TiAlN coating

Solid carbide gives high wear resistance while the TiAlN coating adds heat protection during extended cuts. A straight shank and non-coolant-through design keep the tool simple to clamp and maintain on manual or CNC machines.

Check shank fit and cut depth before ordering

Verify that your holder accepts a 5/8 inch straight shank and that 2.25 inches of flute length covers the required depth of cut. The 5 inch overall length must clear the work envelope and any fixtures in your setup.
