Cleveland C41300 Ball End Mill 0.75 in 4 Flute Hss

Product Description

The CLEVELAND C41300 is a single-end ball end mill designed for finishing operations in metalworking applications. It is constructed from high speed steel (HSS) and features a 4-flute, right-hand spiral configuration with a 30-degree helix angle. The 0.75 inch diameter cutting head and 1.625 inch length of cut make it well suited for producing contoured surfaces, radii, and three-dimensional profiles on cast iron and steel workpieces. The uncoated finish is standard for HSS tooling used in lower-speed or manual-machining environments where regrinding is common practice.

This end mill fits standard CNC machining centers, knee mills, and manual milling machines equipped with a 0.75 inch collet or end mill holder. It is intended for finishing passes on cast iron and steel where a smooth surface finish and accurate radius generation are the primary goals. The Series HG-4B designation identifies it within the CLEVELAND regular-length ball end mill family. It is typically selected by machinists and tool-and-die professionals for die cavities, mold work, and contour milling where HSS tooling is preferred over carbide.

Key Features

• 0.75 inch mill diameter with matching 0.75 inch shank diameter for direct collet mounting
• 1.625 inch length of cut supports moderate-depth contouring and cavity work
• 3.875 inch overall length provides reach while maintaining rigidity in regular-length classification
• 4-flute right-hand spiral construction balances material removal with surface finish quality
• 30-degree helix angle improves chip evacuation on ferrous workpiece materials
• Uncoated HSS construction allows straightforward regrinding to extend tool life

Compatibility

Designed as a standard replacement or direct-use ball end mill for milling machines and machining centers accepting a 0.75 inch shank. Primary workpiece materials are cast iron and steel.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practices. Ensure the machine spindle is fully stopped and locked before inserting or removing the end mill from its holder or collet. Verify shank seating depth and collet torque per machine manufacturer specifications before initiating a cut. Do not exceed the recommended speeds and feeds for HSS tooling in the material being machined.
