Cleveland C40364 Square End Mill

The Cleveland C40364 is a powdered-metal square end mill designed for general milling operations in a workshop or production environment. It suits machinists and maintenance teams who need a reliable inch-series cutter with a Weldon flat for secure tool-holder engagement.

TiCN coating and 0.12 in corner radius

The TiCN coating increases surface hardness and reduces friction, extending tool life in steel and cast-iron workpieces. A 0.12 in corner radius strengthens the cutting edges against chipping, while the Weldon flat prevents pull-out during heavy cuts.

Questions about this item

When will the TiCN coating on this 1 in. diameter end mill need to be replaced?

The TiCN coating wears gradually during milling; replace the cutter when corner radius performance drops below tolerance.

What limits continuous cutting with the 3 in. length of cut?

Heat buildup in the powdered metal substrate and chip evacuation in deep slots become the practical limits during sustained use.
