Cleveland C61884 4-Flute Carbide End Mill

The Cleveland C61884 is a general-purpose square end mill designed for milling operations. It features a 0.40625 in milling diameter and a 7/16 in shank diameter for secure tool holding. The 4-flute carbide construction provides rigidity for a range of materials. This tool suits machinists and fabricators performing slotting, profiling, and pocketing tasks.

Thermals Noise Power

As a solid carbide cutting tool, the C61884 generates heat at the cutting interface during milling. Effective chip evacuation from the four flutes helps manage thermal buildup in the workpiece and tool. Power consumption depends entirely on the machine spindle, feed rate, and material hardness. Noise levels are determined by the machine setup, tool engagement, and workpiece fixturing.

Uncoated Carbide Benefits

The uncoated carbide substrate allows for sharp cutting edges straight from the grinder. This benefits applications involving non-ferrous materials, plastics, or composites where coating adhesion is not required. The straight shank and non-coolant-through design simplify tool holder compatibility. Users must supply appropriate cutting fluids or air blast externally for cooling and chip removal.

Questions about this item

How do I install the 7/16 in shank end mill in my tool holder, and what step is often missed?

Insert the 7/16 in shank fully into a matching collet or holder, tighten securely, and verify the .875 in length of cut clears the workpiece; the step often missed is confirming the shank seats completely against the holder stop to prevent runout.

What maintenance or replacement will the uncoated carbide 4-flute end mill need during its service life?

The uncoated carbide cutting edges will dull with use; plan to resharpen the four flutes periodically or replace the tool when the .40625 in diameter wears below tolerance or edge chipping occurs.

What limit appears first when running this carbide square end mill continuously in steel?

Heat buildup at the uncoated cutting edges typically limits sustained use before tool deflection becomes an issue, especially when the full .875 in length of cut is engaged in harder materials.
