Cleveland C33313 Ball End Mill 0.25 in 4 Flute Hss Ticn

Product Description

The CLEVELAND C33313 is a single-end ball end mill designed for finishing operations in ferrous and cast iron applications. Built from high speed steel and coated with TiCN for extended wear resistance, this tool features a 0.25-inch mill diameter, a 4-flute spiral geometry, and a 30-degree right-hand helix that promotes smooth chip evacuation and surface finish quality. The ball nose profile allows it to produce contoured and radiused surfaces in mold, die, and general machining work. This is a regular-length mill intended for use in conventional CNC mills and manual knee mills by machinists working in production and job shop environments.

The C33313 is suited for finishing passes on cast iron and steel workpieces where surface finish and dimensional accuracy are the priority. The TiCN coating reduces friction and improves tool life compared to uncoated HSS, making it a practical choice for shops running moderate production volumes without access to carbide tooling budgets. The single-end configuration and standard shank size make it compatible with common collet and end mill holder setups found in most machine shops.

Key Features

• Ball nose profile for contouring, radiusing, and 3D finishing passes
• TiCN coating for improved wear resistance and reduced built-up edge on ferrous materials
• 4-flute spiral geometry with 30-degree right-hand helix for efficient chip flow
• High speed steel construction suitable for moderate cutting speeds and interrupted cuts
• Single-end design with a 0.375-inch shank diameter for secure tool holding
• No chipbreaker or variable helix — optimized for consistent finishing cuts

Compatibility

Designed for use on cast iron and steel workpieces. Primary workpiece materials listed by the manufacturer are cast iron and steel. Compatible with standard end mill holders and collets accepting a 0.375-inch shank diameter.

Installation Notes

Installation is performed by qualified machinists following standard tooling procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank fully within the collet or end mill holder to the minimum insertion depth required for the holder type in use. Verify runout with a dial indicator before beginning finishing passes, as TiCN-coated HSS tooling is sensitive to excessive runout at higher surface speeds.
