Cleveland C40041 pneumatic accessory .12
A 3-flute powdered-metal roughing end mill with TiCN coating and a 0.12 in corner radius for heavy material removal
- .12 in corner radius reduces chatter on heavy cuts
- Powdered-metal HSS-E substrate resists wear in tough alloys
- TiCN coating lowers friction and extends tool life
- 3-flute roughing geometry removes material fast
- 1 in diameter suits large-profile milling jobs
Cleveland C40041 Roughing End Mill
The Cleveland C40041 is a three-flute roughing end mill manufactured from powdered metal HSS-E with a TiCN coating. It features a Weldon flat shank for secure tool holding in milling chucks. This cutter is designed for machinists and maintenance teams performing high-volume material removal in steel and difficult alloys. It suits workshops that need a durable, coated rougher for conventional milling machines.
Installation uses a standard Weldon flat shank
Installation uses a standard Weldon flat shank that locks into a matching end-mill holder with a set screw. Ensure the holder bore matches the shank diameter and the set screw engages the flat cleanly. A common issue is insufficient set-screw torque, which lets the tool pull out under heavy roughing loads. Another frequent problem is excessive radial engagement, which overloads the three-flute design and causes chatter or premature flank wear.
Check machine and holder compatibility
Verify that your milling machine spindle accepts the Weldon shank style and that the holder provides adequate clamping length. Confirm the workpiece material and machining parameters suit a powdered-metal rougher with TiCN coating. Ensure coolant or air blast is available to evacuate chips from deep slots or pockets. The 0.12-inch corner radius influences the final profile, so check that the part drawing permits this radius.

Questions about this item
How do I verify the .12 in corner radius is cutting correctly after installing the C40041 end mill?
Measure the finished workpiece radius with a gauge; a consistent .12 in fillet and smooth chip evacuation confirm the three-flute PM+ HSS-E tool is performing as designed.
What accessories come with the Cleveland C40041 roughing end mill and what must I supply?
The cutter itself is supplied; you must provide a compatible Weldon-flat holder, coolant or lubrication, and a rigid milling machine spindle.
Which corner-radius version of the Cleveland roughing end mill should I select for general-purpose profiling?
Choose the C40041 model with its .12 in corner radius when a standard fillet size suits the part geometry and material removal rate required.
