Cleveland C39030 Ball End Mill

The Cleveland C39030 is a 0.3125 in diameter ball end mill made from high speed steel with a TiCN coating. It features a two-flute, single-end design and is intended for non-coolant-through operations. This milling cutter suits general-purpose profiling and contouring tasks in a variety of materials. It is supplied new and ready for use in compatible tool holders.

Suited for manual and CNC milling setups

This tool suits machinists who need a coated high speed steel ball nose for 3D profiling and pocketing work. The two-flute geometry provides good chip clearance in softer materials. It is not for buyers who require a larger milling diameter than 0.3125 in for their application. It is also not for operators who need coolant-through capability for deep cavity evacuation or high-heat alloys.

0.3125 in milling diameter decides fit

The 0.3125 in cutting diameter is the critical specification that determines whether this end mill matches the required feature size and tool path. Verify this dimension against your part drawing and machine clearance before purchase. The TiCN coating extends tool life in abrasive materials compared to uncoated high speed steel. No other diameter or coating option is described for this model number.

Questions about this item

How loud or hot does the C39030 end mill get during extended cutting?

The tool itself has no motor or electronics, so it produces no noise or heat; all sound and temperature come from the machine spindle and the workpiece.

What holder or collet is needed to run the .3125 in shank of this Cleveland cutter?

A standard ER collet or end-mill holder sized for a .3125 in shank will secure the tool in any milling machine spindle.

Will the TiCN coating on this ball-nose mill work well with older manual Bridgeport-style mills?

Yes, the TiCN-coated high-speed steel flutes perform reliably on conventional knee mills as long as speeds and feeds suit the material.
