Cleveland C33308 .75 in HSS Ball Nose End Mill TiN

The Cleveland C33308 is a 0.75 inch high-speed steel ball nose end mill with a titanium nitride coating. It is designed for general-purpose milling tasks where a rounded contour or pocket profile is required. The four-flute geometry provides a smooth finish on ferrous and non-ferrous materials alike. This tool suits machinists and maintenance technicians who need reliable profile cutting capability.

Practical limits of high-speed steel

High-speed steel offers good toughness for interrupted cuts but wears faster than carbide at elevated speeds. The TiN coating reduces friction and extends tool life in steel and cast iron, yet it cannot match the heat resistance of advanced ceramic or cubic boron nitride layers. Users must manage cutting parameters to avoid premature flank wear or coating delamination during heavy roughing passes.

What to check on your existing setup before ordering

Verify that your machine spindle accepts a straight shank matching the tool diameter and that the holder provides adequate rigidity for a four-flute cutter. Confirm the workpiece material is compatible with high-speed steel performance ranges. Ensure coolant delivery or air blast is available if the application generates high heat, since this tool is not coolant-through.

Questions about this item

Should I pick the .75 in diameter or a different size?

The .75 in milling diameter suits medium-width slots and contours; choose a smaller size for tighter radii or a larger one for heavier stock removal.

What does the .75 in diameter mean when the tool is in the spindle?

It sets the maximum width of cut in a single pass and defines the corner radius for 3-D profiling work.

What shank standard does the C33308 use and what does that limit?

It uses a standard straight shank for collet or end-mill holders, limiting use to machines with matching holder capacity.
