Cleveland C42132 Ball End Mill 0.75in 2 Flute Hss

Product Description

The CLEVELAND C42132 is a single-end ball end mill designed for finishing operations in ferrous and cast iron materials. Manufactured from high speed steel (HSS), it features a 0.75-inch mill diameter, a 1.3125-inch length of cut, and a 2-flute spiral configuration with a 30-degree helix angle. The right-hand cutting and right-hand flute direction are standard for conventional milling setups. At 3.625 inches overall length with a 0.5-inch shank diameter, this tool fits a wide range of standard end mill holders. It carries no coating, making it straightforward to inspect for wear and easy to resharpen.

This end mill is suited for finishing passes on cast iron and steel workpieces in job shop, tool room, and production environments. The ball nose profile generates contoured and radiused surfaces, making it a common choice for die work, mold cavities, and profiling cuts. The HG-2B series designation indicates a regular-length geometry optimized for general finishing applications. Machinists and tool room operators working on manual mills or CNC machining centers will find this a standard-duty finishing tool.

Key Features

Compatibility

Designed as a direct-fit replacement or standard tooling addition for end mill holders accepting a 0.5-inch shank diameter. Suitable for use on manual knee mills and CNC machining centers configured for right-hand cutting tools. Primary workpiece materials are cast iron and steel.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully powered down and locked out before changing tooling. Use a properly sized end mill holder or collet and verify runout with a dial indicator before beginning a cut. Follow the tool manufacturer and machine OEM guidelines for recommended speeds and feeds based on material and depth of cut.
