Cleveland C32663 Cobalt End Mill
The Cleveland C32663 is a 4-flute cobalt 8% square end mill designed for general-purpose milling in ferrous and non-ferrous materials. It suits machinists and maintenance technicians who need a durable, center-cutting tool for slotting, profiling and plunging operations. The TiN coating adds wear resistance for extended tool life in production environments.
Weldon Flat Shank Installation
The cutter features a standard Weldon flat on the 1/2 in shank for secure set-screw clamping in milling chucks or end-mill holders. Ensure the flat aligns with the holder screw to prevent slippage under heavy radial loads. The non-coolant-through design means external flood or mist coolant must be directed at the cutting zone for chip evacuation and heat control.
.5 in Diameter with 2 in Length of Cut
The .5 in cutting diameter and 2 in length of cut define the maximum profile width and axial depth per pass in a single operation. Overall length is 4 in with a 1/2 in shank diameter, so verify your machine spindle clearance and workholding envelope before selecting this tool. Buyers needing longer reach or a different corner radius must choose another model.

Questions about this item
How can I confirm the end mill is cutting correctly after installing it in the holder?
A properly seated Weldon flat will lock into the set screw of the holder; verify the 0.5 in shank is fully engaged and listen for smooth, chatter-free cutting with the four-flute cobalt geometry.
What comes with the C32663 end mill and what must I supply separately?
The package contains the single TiN-coated square end mill with 2 in length of cut and 4 in overall length; you must provide a compatible Weldon-flat holder, coolant if required, and the workpiece fixturing.
When should I choose this .5 in diameter cobalt end mill over other sizes?
Select the .5 in cutter when the job calls for a 0.5 in milling diameter, 1/2 in shank fit, and the wear resistance of 8 % cobalt with TiN coating for general-purpose slotting or profiling.
