Harvey Tool 882139-C3 Thread Mill M16 6 Flute Solid Carbide

Product Description

The HARVEY TOOL 882139-C3 is a solid carbide single profile thread mill designed to cut both internal and external M16 threads across a pitch range of 1.50 mm to 2.00 mm. With 6 flutes and an AlTiN coating, this tool handles a range of thread pitches in a single setup, reducing tooling inventory and changeover time. The overall length is 3.5039 inches with a cutting diameter of 13.7 inches as specified, a neck diameter of 8.22 inches, and a neck length of 1.6535 inches. The 14.00 mm shank diameter provides stable clamping in standard toolholders. This tool is installed by CNC machinists and tooling specialists in precision machining environments.

This thread mill is suited for shops producing M16-threaded features in ferrous and non-ferrous materials where a single tool must cover multiple pitches. The internal and external threading capability makes it applicable to both through-hole and boss thread applications. Typical use cases include production machining of fastener bosses, threaded inserts, and mating threaded components on CNC machining centers. The AlTiN coating provides heat resistance for higher-speed cutting in hardened or abrasive materials.

Key Features

• Single profile design covers M16x1.5 through M16x2 pitch range in one tool
• Cuts both internal and external threads, reducing dedicated tooling requirements
• 6-flute geometry for improved surface finish and chip evacuation
• AlTiN coating for elevated heat resistance and extended tool life in abrasive materials
• Solid carbide construction for rigidity and dimensional stability
• 14.00 mm shank diameter for secure, concentric clamping in standard toolholders

Compatibility

Designed as an OEM-style thread milling solution for CNC machining centers capable of helical interpolation with a suitable toolholder accepting a 14.00 mm shank diameter.

Installation Notes

Thread milling requires a CNC machining center with helical interpolation capability. Verify toolholder runout before use, as excessive runout directly affects thread quality and tool life. Power down the machine and follow lockout procedures before changing or inspecting the tool. Program thread direction, pitch, and helix path according to the machine controller and tool documentation.
