Cleveland C33325 Ball End Mill 0.375 in 4 Flute Hss

Product Description

The CLEVELAND C33325 is a single-end ball end mill designed for finishing operations in ferrous and cast iron materials. Built from high speed steel, it features a 0.375-inch diameter, a 1.5-inch length of cut, and a 30-degree helix angle across four right-hand spiral flutes. The uncoated finish suits applications where coating is not required or where re-sharpening is planned. At 3.25 inches overall length with a 0.375-inch shank diameter, this tool fits standard milling chucks and collets used in manual and CNC machining environments. Machinists and toolroom operators select this end mill for contoured surface work, ball-nose profiling, and semi-finish passes.

This end mill is intended for use in milling machines, machining centers, and toolroom mills handling cast iron and steel workpieces. The HG-4B series regular-length geometry suits general-purpose finishing where extended reach is not required. The right-hand cutting and right-hand flute direction are standard for conventional and climb milling setups. It is a single-end tool, so once the cutting end is worn, the tool is replaced or re-sharpened rather than flipped.

Key Features

• 0.375-inch ball end diameter for contoured and profiled surface finishing
• Four right-hand spiral flutes with 30-degree helix angle for smooth chip evacuation
• High speed steel construction supports re-sharpening and use without coolant-through requirements
• Uncoated finish suitable for cast iron and steel finishing operations
• Single-end design, 3.25 inches overall length with 0.375-inch shank for standard toolholding
• HG-4B series regular-length geometry — no extended reach, no chipbreaker, no variable helix

Compatibility

Designed as an OEM-style replacement or direct-use end mill for standard milling machine spindles and CNC machining centers accepting a 0.375-inch straight shank. Primary workpiece materials are cast iron and steel.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the 0.375-inch shank in a properly sized collet or end mill holder and torque to the toolholder manufacturer specification. Confirm spindle and workpiece are fully stopped before tool changes. Follow shop safety procedures and applicable OSHA machine guarding requirements when operating milling equipment.
