Cleveland C41293 Ball End Mill 0.5 in 4 Flute Hss

Product Description

The CLEVELAND C41293 is a single-end ball end mill designed for finishing operations in ferrous materials including cast iron and steel. Built from high speed steel, it features a 0.5-inch mill diameter, a 1.25-inch length of cut, and a 4-flute spiral configuration with a 30-degree helix angle. The right-hand cutting and flute direction suits standard milling setups without special spindle adaptation. This tool is installed by machinists and tool-and-die professionals in CNC and manual milling applications where a precise ball-nose profile is required for contoured or radiused surfaces.

This end mill is suited for finishing passes on cast iron and steel workpieces in both job shop and production environments. The HG-4B series designation places it in a regular-length category, making it appropriate for general-purpose milling setups where extended reach is not required. The 0.5-inch shank diameter matches standard ER and end mill holder sizes commonly used in vertical and horizontal machining centers. Coolant-through capability is not available on this tool, so flood or mist cooling at the periphery is the recommended approach for heat management during cuts.

Key Features

• 0.5-inch ball end mill diameter with 1.25-inch length of cut for finishing contoured surfaces
• 4-flute spiral design with 30-degree helix angle for smooth chip evacuation in steel and cast iron
• High speed steel construction provides toughness in interrupted and general milling cuts
• Single-end configuration with right-hand cutting direction for standard milling machine spindles
• Uncoated finish — suited for applications where re-sharpening or specific coating compatibility is needed
• Regular length at 3.25 inches overall length with 0.5-inch shank for rigid, low-deflection setups

Compatibility

Designed for use with cast iron and steel workpieces. The 0.5-inch shank diameter is compatible with standard end mill holders and collet chuck systems sized for 1/2-inch tooling. Part of the CLEVELAND HG-4B series.

Installation Notes

Installation is performed by a machinist or toolroom professional. Ensure the milling machine spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the tool holder and verify runout with a dial indicator before engaging a cut. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and depth of cut being used.
