Harvey Tool 24675-C3 Ball End Mill 1.90mm 4 Flute Carbide

Product Description

The HARVEY TOOL 24675-C3 is a miniature solid carbide ball end mill designed for high-precision milling in steel, stainless steel, and cast iron. It features a 1.90 mm (0.0750 inch) mill diameter, a 4-flute spiral configuration, and a 30-degree right-hand helix that promotes efficient chip evacuation in both roughing and finishing operations. The AlTiN PVD coating provides thermal resistance and extended tool life at elevated cutting temperatures. With a stub-length reach of 0.1120 inches, this tool is built for tight-tolerance work where rigidity matters. Machinists and CNC operators install this tool in machining centers running steel and ferrous alloys.

This end mill fits into light-duty to medium-duty CNC milling applications where a small-diameter ball profile is required for contoured surfaces, 3D profiling, or finishing passes in ferrous materials. The 1/8-inch straight cylindrical shank makes it compatible with standard collet systems used in vertical and horizontal machining centers. The stub-length geometry reduces deflection in difficult-to-reach features while maintaining the rigidity needed for aggressive feed rates in steel and cast iron. Single-end configuration means the tool is indexed and replaced as a unit rather than flipped.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous alloys
• AlTiN PVD coating rated for high-temperature cutting in steel and stainless steel
• 4-flute spiral design supports both roughing and finishing in a single tool
• 30-degree right-hand helix promotes chip flow and reduces heat buildup
• Stub-length reach (0.1120 inches) minimizes deflection in tight-clearance cuts
• 0.0375-inch nose radius delivers accurate ball-profile contours on 3D surfaces

Compatibility

Designed for use with standard 1/8-inch collet systems in CNC vertical and horizontal machining centers. Primary workpiece materials are steel, stainless steel, and cast iron (ISO material codes P, M, and K).

Installation Notes

This tool is installed by a machinist or CNC operator using a compatible 1/8-inch precision collet or toolholder. Ensure the machine spindle is fully stopped and the tool path program is verified before loading. Confirm collet runout is within tolerance before engaging the cut, as runout on small-diameter tools accelerates wear and can cause tool breakage. No coolant-through capability is present on this tool; external coolant or mist lubrication should be directed at the cutting zone when applicable.
