- 3-flute design evacuates chips efficiently during heavy roughing cuts
- Powdered metal substrate resists wear in demanding milling applications
- TiCN coating reduces friction and extends tool life
- Weldon flat shank provides secure, non-slip clamping in holders
- 75 in diameter suited for medium-size material removal tasks
Cleveland C40066 roughing end mill overview
The Cleveland C40066 is a 0.75 in roughing end mill built from powdered metal with a TiCN coating. It features a 3-flute design and a Weldon flat shank for secure tool holding. This tool is intended for heavy material removal in general milling applications.
Suited for aggressive stock removal.
Machinists who need rapid metal removal in steel or tough alloys will find this rougher effective. The coarse flute geometry prioritises chip evacuation over surface quality. Shops requiring a smooth final finish or tight dimensional tolerances should select a dedicated finishing end mill instead.
0.75 in milling diameter with 2.25 in flute length
The cutter diameter is 0.75 in and the flute length measures 2.25 in, giving a total tool length of 4 1/2 in. These dimensions determine whether the tool fits the workpiece envelope and machine spindle clearance. Verify both measurements against your setup before ordering.

Questions about this item
What spindle interface does the 0.75 in roughing end mill use?
It uses a Weldon flat shank, the standard side-lock interface for inch-size milling cutters.
What shank diameter and clearance does the cutter need to mount?
The shank is 0.75 in diameter and requires a holder with a matching Weldon flat pocket and at least 2.25 in of usable length.
How is the TiCN-coated rougher installed, and what step is often missed?
Insert the shank fully, align the flat with the set-screw, torque the screw to the holder maker's spec, and verify the 0.12 in corner radius clears the workpiece before cutting.
