Harvey Tool 41473-C3 Thread Mill 9/16 6 Flute Altin Carbide

Product Description

The HARVEY TOOL 41473-C3 is a solid carbide single profile thread mill designed to cut both internal and external threads across a range from 9/16-12 to 9/16-32, covering 12 to 32 TPI. With a 0.4-inch cutting diameter and a 0.5-inch shank diameter, this tool mounts in standard milling setups and handles a wide thread-pitch range in a single tool. The 6-flute geometry and AlTiN coating support extended tool life in ferrous and high-temperature alloys. It is installed and operated by CNC machinists and tool-and-die professionals working in production or job-shop environments.

This thread mill is suited for applications requiring precise single-point helical interpolation on both internal bores and external diameters within the 9/16-inch thread family. Its single-profile design makes it appropriate for low-volume production, prototype work, or situations where thread size flexibility is needed without a full-form dedicated tool. Typical materials include steel, stainless, and similar difficult-to-machine alloys where AlTiN coating provides thermal resistance and reduced built-up edge.

Key Features

• Cuts internal and external threads from 12 to 32 TPI in a single tool
• Solid carbide construction for rigidity and dimensional stability
• AlTiN coating improves heat resistance and extends tool life in ferrous and high-temp materials
• 6-flute design for balanced cutting forces during helical interpolation
• 0.27-inch neck diameter with 1.25-inch neck length provides clearance in deep-bore applications
• 3-inch overall length accommodates standard milling machine and machining center setups

Compatibility

Designed for use on CNC machining centers capable of helical interpolation; compatible with 9/16-12 through 9/16-32 thread specifications for both internal and external thread forms.

Installation Notes

Thread mills require a CNC control capable of helical interpolation; confirm the machine program is correct before engaging the cut. Secure the tool in a precision collet or end-mill holder sized for a 0.5-inch shank and verify runout before operation. Do not use in manual milling machines or non-interpolating setups. Follow shop-specific speeds and feeds for the workpiece material and confirm correct thread direction in the program.
