Cleveland C61039 Carbide End Mill
The Cleveland C61039 is a two-flute carbide square end mill built for general-purpose milling. Its uncoated solid carbide construction suits machinists and maintenance teams cutting ferrous and non-ferrous materials on CNC or manual equipment. The straight shank fits standard 5/16-inch tool holders for immediate use.
Thermals noise and power draw
Carbide retains hardness at elevated cutting temperatures, reducing the need for frequent tool changes during extended runs. The uncoated surface avoids coating delamination in high-heat passes. Two flutes provide ample chip clearance, lowering cutting forces and the power demanded from the spindle motor.
0.3125 inch milling diameter
The 0.3125-inch cutting diameter and 1.625-inch length of cut define the maximum slot width and depth per pass. The 4-inch overall length and 5/16-inch shank diameter set the reach and holder compatibility. Shops needing a larger diameter or coolant-through capability must select a different tool.

Questions about this item
How do I install the 0.3125 in carbide end mill in a 5/16 in collet, and what step is often missed?
Insert the shank fully until the flute fade-out clears the collet face, then torque the nut to the holder manufacturer's spec; the common miss is leaving a gap that lets the tool pull out under load.
What maintenance or replacement will this uncoated carbide end mill need during its life?
The 2-flute cutting edges will dull and require re-grinding or replacement; no coating exists to refresh, so flank wear is the only indicator to watch.
What limit appears first when slotting at full 1.625 in length of cut in steel?
Deflection of the 4 in overall length carbide shank causes chatter before the flute capacity is reached, forcing reduced radial engagement or shorter passes.
