Cleveland C39121 Square End Mill

The Cleveland C39121 is a two-flute high-speed steel square end mill with a TiCN coating for extended tool life. It has a milling diameter of 0.6875 in and a length of cut of 2.25 in with a 3/4 in Weldon flat shank. This cutter is suited for general-purpose slotting and profiling in a range of materials.

Machinists needing a coated HSS slot cutter

This tool suits machinists who need a coated high-speed steel end mill for standard milling operations on manual or CNC machines. The TiCN coating improves wear resistance in ferrous alloys. Buyers who require carbide substrate for high-speed machining or a different flute count for specific chip evacuation should look at other tooling options.

0.6875 in cutting diameter

The 0.6875 in cutting diameter is the primary specification that determines whether this end mill matches the required feature size in the workpiece. Verify this dimension against your drawing or setup before ordering.

Questions about this item

How often will the TiCN coating need to be refreshed on this C39121 end mill?

The TiCN coating is not renewable; once it wears through the high-speed steel substrate is exposed and the tool must be replaced.

What limits continuous cutting with the 2.25 in length of cut on this square end mill?

Chip evacuation in deep slots becomes the practical limit; the 2-flute geometry clears less volume than multi-flute tools so heat builds faster in sustained passes.

How much heat does the 0.6875 in diameter cutter generate during an all-day production run?

High-speed steel with TiCN runs hotter than carbide at the same speed; expect noticeable heat at the shank interface during extended cycles.
