Harvey Tool 74310-C3 Ball End Mill 0.0100 in 4 Flute Carbide

Product Description

The HARVEY TOOL 74310-C3 is a miniature solid carbide ball end mill designed for high-precision milling in demanding ferrous and hard material applications. With a 0.0100-inch cutting diameter, 4-flute geometry, and a 30-degree helix angle, this tool delivers both roughing and finishing capability in a single-end configuration. The AlTiN PVD coating provides thermal resistance and surface hardness, extending tool life in steel, stainless steel, and cast iron. A 0.1250-inch straight cylindrical shank and 1.5000-inch overall length make it compatible with standard collet and end mill holder setups used by precision machinists and toolroom operators.

This end mill is suited for CNC milling operations requiring tight tolerances in small-feature work such as micro-cavities, detailed contours, and finish passes on ferrous workpieces. The stub-and-standard series designation places it within miniature end mill applications where rigidity is prioritized. Primary workpiece materials include steel, stainless steel, and cast iron. The 0.0050-inch nose radius and 0.0300-inch reach length make it appropriate for shallow pocket milling and fine detail work where tool deflection must be minimized.

Key Features

• 0.0100-inch ball end cutting diameter with plus or minus 0.0005-inch diameter tolerance
• 4-flute spiral flute design supports both roughing and finishing material removal
• AlTiN PVD coating for thermal resistance in steel and stainless steel applications
• 30-degree right-hand helix with right-hand cutting direction for standard CNC spindle use
• Solid carbide construction provides rigidity and wear resistance at miniature diameters
• 0.1250-inch straight cylindrical shank fits standard collet systems without modification

Compatibility

Designed for use with standard 1/8-inch collets and end mill holders on CNC machining centers and manual mills. Suitable for steel, stainless steel, and cast iron workpiece materials as specified by the manufacturer.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine in a safe, locked-out state. Ensure the collet and holder are clean and free of chips before seating the shank to full depth. At miniature diameters, avoid excessive overhang beyond the stated reach length to minimize deflection and tool breakage. Always verify runout with a dial indicator before beginning a cut at this diameter class.
