Cleveland C40072 Square End Mill

The Cleveland C40072 is a square end mill designed for milling operations in metalworking applications. It features a 0.375 in milling diameter and a 0.75 in length of cut with an overall length of 2 1/2 in. This uncoated powdered metal tool suits machinists and maintenance professionals performing general-purpose milling tasks.

Weldon flat shank installation

The tool uses a 3/8 in shank diameter with a Weldon flat for secure clamping in compatible tool holders. Proper alignment in the holder prevents runout and ensures the flat seats correctly against the set screw. Issues typically arise if the holder is worn or if the set screw does not engage the flat fully.

Powdered metal under sustained load

The uncoated powdered metal substrate maintains hardness during extended cutting passes in ferrous materials. Heat builds steadily in deep slots or profile cuts without coatings to reduce friction. Chip evacuation becomes critical when the 0.75 in length of cut is fully engaged for long periods.

Questions about this item

How can I confirm the end mill is cutting correctly after installation?

The tool should produce a clean, square shoulder at the full .75 in length of cut with no chatter when run at the recommended speed for powdered metal cutters.

What comes in the package and what must I supply separately?

The box contains the C40072 square end mill only; a Weldon-compatible tool holder and coolant or cutting fluid are not included.

When should I choose this .375 in diameter mill over other sizes?

Select this 3/8 in shank, .375 in diameter cutter when the job requires a .75 in depth of cut in a single pass and the machine accepts a Weldon flat shank.
