Cleveland C33347 Ball End Mill 0.5 in 4 Flute Hss

Product Description

The CLEVELAND C33347 is a single-end ball end mill designed for finishing operations in ferrous materials including cast iron and steel. Built from high speed steel with a 4-flute spiral configuration and a 30-degree right-hand helix, it delivers smooth surface finishes in contoured and profiled cuts. The 0.5-inch mill diameter pairs with a matching 0.5-inch shank diameter, a 3-inch length of cut, and a 5-inch overall length. The uncoated finish suits standard finishing passes where coating is not required. This tool is part of the HG-4B series and is intended for use by machinists and tool-and-die professionals working on milling machines or CNC machining centers.

The C33347 is suited for finishing work on cast iron and steel workpieces in both manual and CNC milling applications. The regular-length geometry and 3-inch length of cut provide clearance for moderate-depth profiling and cavity work without excessive tool deflection. The right-hand cutting and flute direction make it compatible with conventional right-hand spindle setups. This end mill is appropriate for job shops, maintenance machining, and production environments where HSS tooling is the specified standard.

Key Features

• 4-flute spiral design for efficient chip evacuation during finishing passes
• 30-degree right-hand helix angle reduces cutting forces on ferrous materials
• Ball end geometry enables contouring, profiling, and 3D surface finishing
• High speed steel construction provides toughness in interrupted cuts
• Single-end design with uncoated finish for standard finishing applications
• HG-4B series regular length for balanced reach and rigidity

Compatibility

Designed as an OEM-style replacement and standard fit for milling machines and CNC machining centers accepting a 0.5-inch straight shank end mill with right-hand cutting direction.

Installation Notes

This end mill is installed by machinists into a compatible collet, end mill holder, or set-screw holder rated for the 0.5-inch shank diameter. Ensure the spindle and machine are fully powered down and locked out before changing tooling. Inspect the holder for runout before use, as excessive runout will accelerate wear on HSS tools. Follow your machine manufacturer and shop safety guidelines for speeds, feeds, and clamping torque when securing the tool holder.
