  • TiCN coating extends tool life
  • Ball nose geometry enables 3D contouring

What this tool does

The Cleveland C33362 is a four-flute high-speed steel ball nose end mill with a TiCN coating. It is intended for general-purpose milling in ferrous and non-ferrous materials where a rounded profile is required. The 0.25 inch cutting diameter suits light profiling and contouring work on manual or CNC machines.

Practical limits of the standard

High-speed steel offers good toughness but lower hot hardness than carbide, so cutting speeds must stay moderate to avoid premature wear. The TiCN coating improves lubricity and heat resistance, yet the tool is not designed for coolant-through operation, limiting chip evacuation in deep pockets or high-material-removal jobs.

Installation and common issues

The plain shank fits standard collets and end mill holders; ensure the holder is clean and the tool is clamped to the recommended depth to prevent runout. Common problems include chatter from excessive overhang, chip packing in the flutes when machining sticky alloys, and coating delamination if the tool is run beyond its recommended speed range.

Should I pick the .25 in ball nose or a different diameter?

The .25 in milling diameter is the only size offered for this Cleveland C33362 end mill, so choose it when your job calls for a quarter-inch ball profile.

What does the .25 in diameter mean when the tool is in the spindle?

It produces a quarter-inch wide cut with a matching ball radius, suited for 3-D contouring and finishing passes in a milling machine.

What shank standard does the C33362 use and what holders accept it?

The tool is a standard High Speed Steel ball end mill with TiCN coating; it fits common collet or end-mill holders sized for its shank.
