Harvey Tool 959540-C6 Thread Mill 10-24 to 10-36 Solid Carbide

Product Description

The HARVEY TOOL 959540-C6 is a single profile thread mill designed to cut both internal and external threads in the 10-24 to 10-36 range, covering 24 to 36 TPI. Built from solid carbide and finished with an AlTiN Nano coating, it delivers hardness and heat resistance suited for threading ferrous and nonferrous materials. The tool features a 0.135-inch cutting diameter, a 0.250-inch shank diameter, and an overall length of 2.5 inches. With 5 flutes and a neck diameter of 0.086 inches, it provides clean thread profiles in tight-tolerance applications. Machinists and CNC programmers working on precision parts rely on this tool for single-point thread milling passes that reduce cutting forces and allow thread size adjustment through toolpath offsets.

This thread mill is suited for use on CNC machining centers in both production and job-shop environments. It handles a wide range of materials where thread milling is preferred over tapping, including hardened steels and difficult alloys. The ability to mill internal and external threads with a single tool makes it a versatile option for shops threading Number 10 fastener holes and studs. The 0.625-inch neck length provides adequate clearance for most standard-depth threading operations in this size class.

Key Features

• Cuts internal and external threads from 10-24 to 10-36 (24 to 36 TPI) with a single tool
• Solid carbide construction for rigidity and long tool life
• AlTiN Nano coating improves heat and wear resistance in ferrous materials
• 5-flute geometry for efficient chip evacuation and smooth thread finish
• 0.086-inch neck diameter allows access in confined bore geometries
• 0.625-inch neck length supports standard-depth threading applications in this size range

Compatibility

Designed for use on CNC machining centers capable of helical interpolation; compatible with standard 1/4-inch collet and end mill holders for thread milling operations in the Number 10 thread size class.

Installation Notes

Thread milling with this tool requires a CNC control capable of helical interpolation. Verify spindle speed, feed rate, and helical pitch settings against the manufacturer's programming guidelines before cutting. Secure the shank fully in a collet or shrink-fit holder to minimize runout, which directly affects thread quality. Do not use in manual milling machines or any setup that cannot maintain consistent helical movement.
