Cleveland C33303 4-Flute HSS Ball Nose End Mill TiN

SKU CH-5YES-92ESJ

A four-flute HSS ball-nose end mill with TiN coating for 0.25 in milling diameter

  • 4-flute design improves chip evacuation for smoother milling
  • TiN coating reduces friction and extends tool life
  • High-speed steel construction handles general-purpose cutting tasks
  • 25 in diameter suits precision profiling and slotting
  • Ball nose geometry creates contoured surfaces and radii

Cleveland C33303 Ball Nose End Mill

The Cleveland C33303 is a four-flute high-speed steel ball nose end mill with a TiN coating. It is designed for general-purpose milling and contouring in a variety of materials. Machinists and maintenance technicians use it for profiling and finishing operations on manual or CNC equipment.

Sustained Cutting Performance

The TiN coating increases surface hardness and reduces friction during extended cutting cycles. Four flutes provide efficient chip evacuation and a smoother finish compared to two-flute designs. High-speed steel construction maintains edge integrity under continuous load without the brittleness of carbide alternatives.

Quarter-Inch Milling Diameter

This tool features a 0.25 in milling diameter that determines the minimum radius and stepover possible. Shops needing larger or smaller cutting diameters must select a different size. The non-coolant-through design requires external coolant or air blast for heat management.

Questions about this item

How much heat builds up in the TiN coating when the 0.25 in end mill runs all day?

The TiN coating reduces friction and heat during extended milling, helping the HSS tool stay cooler than uncoated alternatives under the same conditions.

What shank size must my tool holder accept for the C33303 to fit?

The end mill uses a standard shank that matches common collets and holders for 0.25 in milling diameter tools in HSS ball nose configurations.

Will this 4-flute HSS ball nose mill work in my older manual milling machine?

Yes, the HSS construction and standard geometry make it compatible with older manual and CNC machines that accept 0.25 in shank tooling.
