Cleveland C61871 Carbide End Mill
The Cleveland C61871 is a four-flute carbide square end mill designed for general-purpose milling tasks. It suits machinists and maintenance teams needing a rigid, uncoated tool for slotting, profiling and plunge cuts in a range of ferrous and non-ferrous materials. The straight shank fits standard 3/8 inch tool holders on manual or CNC knee mills.
Uncoated Carbide Limits
An uncoated carbide substrate relies on its inherent hardness and heat resistance rather than a surface coating. This restricts maximum cutting speeds and feed rates compared with coated alternatives, especially in abrasive or high-temperature alloys where built-up edge and crater wear accelerate. The tool lacks internal coolant passages, so external flood or mist cooling must manage chip evacuation and thermal load during deep pockets or full-width slots.
0.375 Inch Diameter Decides Fit
The 3/8 inch cutting diameter and matching shank diameter determine whether this mill matches the feature size and tool holder capacity of the job. If the programmed radius, slot width or holder bore differs, the cutter cannot be used without changing the setup or selecting a different diameter.

Questions about this item
Which Cleveland end-mill diameter matches my milling job?
This cutter has a 0.375 in milling diameter and a 3/8 in shank, so it fits 3/8 in tool holders and cuts a 3/8 in wide slot in one pass.
What does the 1 in length of cut mean when the tool is in the spindle?
You can plunge or profile up to 1 in deep before the shank contacts the workpiece, giving full flute engagement for slots or pockets of that depth.
How does the straight shank and uncoated carbide affect tool holding and cutting?
The plain 3/8 in straight shank clamps in standard collets or end-mill holders, while the uncoated carbide works well in non-ferrous metals and plastics without coating buildup.
