Cleveland C61869 End Mill Overview
The Cleveland C61869 is a 4-flute carbide square end mill built for general-purpose milling tasks. It features a 0.359375 in cutting diameter and a 3/8 in shank for secure toolholder engagement. The uncoated solid carbide construction suits a range of ferrous and non-ferrous materials in CNC or manual operations.
Suitability for Machining Applications
This end mill suits shops and machinists performing slotting, profiling or finishing cuts where a standard length of cut is sufficient. The 0.875 in flute length limits reach in deep cavities or high aspect-ratio pockets. Buyers needing extended reach, coolant-through capability or a coated tool for higher heat resistance should evaluate other geometries.
Decisive Specification: Length of Cut
The 0.875 in length of cut determines the maximum axial engagement in a single pass. Verify that this depth matches your programmed step-down and part feature depths before ordering. If your operation requires longer flute engagement, a different tool with a greater length of cut is required.

Questions about this item
How do I install the C61869 end mill in a collet holder, and what step is often missed?
Insert the 3/8 in shank fully into a matching collet, tighten the collet nut to the holder's rated torque, and verify the 0.875 in length of cut clears the fixture before starting the spindle.
What maintenance or replacement will the uncoated carbide tool need?
Inspect the four flute cutting edges after each job; resharpen or replace the mill when the square corners show chipping or when flank wear reduces dimensional accuracy on the 0.359375 in diameter.
What limit appears first during a long production run with this mill?
Heat buildup in the uncoated carbide body typically limits sustained feed rates before tool deflection becomes an issue on the 2 1/2 in overall length.
