Harvey Tool 73039 Square End Mill 0.039 in 4 Flute Carbide

Product Description

The HARVEY TOOL 73039 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. With a 0.039-inch cutting diameter and a 0.117-inch length of cut, this tool is built for fine detail work in metals, composites, and engineering plastics. The four-flute geometry with a 30-degree helix angle promotes chip evacuation and surface finish quality. Center-cutting capability allows direct plunging into the workpiece. The 1/8-inch shank diameter and 1.5-inch overall length make this tool compatible with standard collet chucks and tool holders used in CNC machining centers and manual mills.

This end mill is suited for finish milling, slotting, and profiling operations where small-diameter tooling is required. It is commonly used in precision machining environments including mold and die shops, aerospace component machining, and medical device manufacturing. The uncoated solid carbide construction offers consistent performance across a range of workpiece materials. Right-hand cut and right-hand flute configuration is standard for conventional CNC milling setups. The tool is sold as a single unit with a minimum order quantity of one.

Key Features

• 0.039-inch cutting diameter for fine detail and micro-milling work
• Solid carbide construction for rigidity and wear resistance
• Four flutes with 30-degree helix angle for improved chip flow and surface finish
• Center-cutting design allows direct plunge entry into the workpiece
• Uncoated finish suitable for a broad range of workpiece materials
• Right-hand cut, right-hand flute configuration for standard CNC spindle use

Compatibility

Designed for use in CNC machining centers and manual mills equipped with collet systems or tool holders accepting a 1/8-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and machine power is locked out before loading or unloading the tool. Seat the shank fully and securely in the collet or tool holder to the recommended engagement depth to minimize runout. Verify spindle direction is set to right-hand rotation before initiating any cut.
