Cleveland C61887 Carbide End Mill
The Cleveland C61887 is a 4-flute carbide square end mill designed for general-purpose milling in a machine shop. Its uncoated carbide construction suits ferrous and non-ferrous materials when coolant is supplied externally. The straight shank fits standard ER collets or Weldon holders for rigid clamping. Machinists gain a reliable tool for slotting, profiling and facing operations.
Who this suits and who should look elsewhere
This cutter suits CNC operators and manual machinists who need a 7/16 in shank diameter and a 1 in length of cut for medium-depth pockets. It is not for shops that require through-coolant delivery for deep-hole evacuation or high-heat alloys. Buyers needing a coated tool for extended life in abrasive composites should select a different geometry. Production lines running unattended overnight may prefer a corner-radius design to reduce chipping.
Deciding specification: 0.4375 in cutting diameter
The 0.4375 in milling diameter is the single dimension that determines whether this end mill matches the feature size on your drawing. Verify the pocket width or slot tolerance before ordering because the shank diameter and overall length are fixed by the catalogue standard. No other specification changes the fundamental fit of this tool in your programmed toolpath.

Questions about this item
How do I install the C61887 end mill in a 7/16 in collet without runout?
Clean the 7/16 in shank and collet bore, insert the tool to full grip length, and tighten the collet nut to the holder’s specified torque so the 0.4375 in diameter runs true.
When should the uncoated carbide flutes be replaced?
Replace the tool when the four flute edges show visible rounding, chipping, or when surface finish degrades on the workpiece.
What limits continuous slotting in steel with this 1 in length of cut?
Chip evacuation in the deep 1 in flute length becomes the first constraint, requiring reduced axial depth or peck cycles to prevent packing.
