Cleveland 80177 Carbide Square End Mill
This Cleveland 80177 is a 2-flute carbide square double-end general-purpose end mill. It is made for milling operations that need a square profile and a TiAlN coating. The tool suits machinists and fabricators who work with standard milling setups.
Machinists needing a 0.21875 in diameter tool
This cutter fits users who need a 0.21875 in milling diameter with a 3/8 in shank and a 0.5625 in length of cut. The overall length is 3 1/2 in and it is non-coolant-through. Buyers who require a different diameter, a coolant-through design, or a necked configuration should look at something else.
TiAlN coated carbide with straight shank
The single specification that decides fit is the 0.21875 in milling diameter combined with the 3/8 in straight shank. This dimension pair determines whether the tool matches the holder and the workpiece requirement.

Questions about this item
How is the 0.21875 in carbide end mill installed in a tool holder, and what step is often missed?
Clamp the 3/8 in shank securely in a matching collet or holder, ensuring the shank seats fully; the step often missed is verifying the 0.5625 in length of cut clears the workpiece before starting the spindle.
What maintenance or replacement will the TiAlN coated carbide end mill need later?
The TiAlN coating wears gradually; plan to resharpen or replace the tool once the cutting edges show rounding or the coating is depleted, which appears as increased cutting forces or poorer surface finish.
What limit appears first when running the 3 1/2 in overall length end mill under sustained cuts?
Deflection of the 3/8 in shank over the 3 1/2 in overall length typically limits depth of cut or feed rate before the carbide substrate reaches its thermal limit.
