Cleveland C31197 roughing end mill
The Cleveland C31197 is a 5-flute cobalt roughing end mill designed for heavy material removal in milling operations. Its coarse tooth geometry breaks chips efficiently during aggressive roughing passes. The Weldon flat shank provides secure clamping in standard tool holders. Machinists running manual or CNC mills will value the tool’s rigidity for hogging out stock quickly.
Cobalt substrate and uncoated surface
The 8% cobalt high-speed steel substrate offers hot hardness that resists softening at elevated cutting temperatures. Because the tool is uncoated, it avoids the adhesion issues that coated tools can exhibit in certain ferrous alloys. The non-coolant-through design means chips must be evacuated externally by flood coolant or air blast. Users must plan chip clearance strategies for deep slots or pockets where evacuation is restricted.
1-inch diameter with 2-inch length of cut
The 1-inch cutting diameter and 2-inch flute length suit medium-depth roughing profiles in a single pass. The 4-1/2-inch overall length and 1-inch shank diameter keep overhang manageable on standard tool holders. The five-flute configuration distributes cutting forces evenly but limits chip space compared to fewer-flute roughers. Shops needing finer finishes or deeper axial engagement will need a separate finishing tool or a different geometry.

Questions about this item
How do I know the C31197 is the right roughing end mill for my job?
The C31197 is a 5-flute cobalt roughing end mill with a 1 inch milling diameter, 2 inch length of cut, 4-1/2 inch overall length, 1 inch Weldon flat shank, and uncoated finish — match those specs to your tool holder and material requirements.
What does the 1 inch milling diameter mean when I put this in my machine?
A 1 inch milling diameter gives you a wide cutting path for heavy stock removal in a single pass, reducing cycle time on large workpieces while the coarse 5-flute geometry breaks chips efficiently.
What does the Weldon flat shank mean for tool holding?
The 1 inch Weldon flat shank locks into standard Weldon end mill holders with a set screw on the flat, providing secure, non-pullout clamping for high-torque roughing cuts.
