Cleveland 80157 Roughing End Mill
The Cleveland 80157 is a four-flute carbide roughing end mill designed for high-volume material removal in milling operations. Its 0.75 inch cutting diameter and 1.5 inch length of cut suit heavy roughing passes in steel and other ferrous alloys. The TiAlN coating adds wear resistance at elevated cutting temperatures.
Machinists running aggressive roughing cycles
This tool suits machinists who need rapid stock removal with a rigid carbide substrate and a Weldon flat for secure holder clamping. Shops requiring coolant-through capability or a necked reach for deep cavities should look at a different tool because this model has neither feature.
TiAlN coating and Weldon flat
The TiAlN coating extends tool life when dry machining or running with minimal lubrication by reducing heat buildup on the cutting edges. The Weldon flat prevents tool pull-out during high-torque roughing cuts, keeping the cutter locked in the holder without additional clamping hardware.

- 4-flute design clears chips efficiently in heavy cuts
- .75 in diameter suits medium milling operations

Questions about this item
What size Weldon-shank holder do I need for the 3/4 in shank on this 80157 end mill?
Use a holder with a 3/4 in bore that clamps on the Weldon flat; the shank diameter is 3/4 in and overall length is 4 in.
Can I run this .75 in carbide rougher on a manual knee mill that only takes R8 collets?
Not directly — the tool has a 3/4 in Weldon-flat shank, so you need a Weldon-to-R8 adapter or a 3/4 in Weldon end-mill holder that fits your spindle.
How do I verify the 1.5 in length of cut is engaged correctly after setup?
Measure the flute length showing above the holder; it should match the 1.5 in length of cut, and the TiAlN coating should show even wear across all four flutes after the first pass.
