Harvey Tool 842929-C3 Thread Mill M10x1.5 4 Flute Carbide

Product Description

The HARVEY TOOL 842929-C3 is a solid carbide helical flute thread mill designed for cutting M10x1.5 threads in both internal and external applications. With 4 flutes and an AlTiN coating, this tool delivers efficient material removal and extended tool life in ferrous and hard materials. The 0.311-inch cutting diameter and 1.122-inch length of cut allow the tool to produce full-form threads in a single helical pass on a CNC machining center. The 0.375-inch shank diameter provides rigid coupling to standard ER or milling collet systems. At 3.5 inches overall length, the tool is suited for moderate-reach threading operations without sacrificing rigidity.

This thread mill is used in CNC milling operations where a single tool must handle both internal and external M10x1.5 thread profiles. Typical applications include production machining of steel, stainless steel, cast iron, and other materials where thread tapping is impractical due to blind holes, hard materials, or the need to adjust thread fit without changing tooling. It is installed and operated by CNC machinists and toolroom professionals in job shops, OEM manufacturing, and maintenance and repair environments.

Key Features

• Cuts both internal and external M10x1.5 threads with a single tool
• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating improves heat resistance and extends tool life in ferrous alloys
• 4-flute helical geometry promotes smooth chip evacuation and surface finish
• 0.375-inch shank diameter fits standard ER collet and milling chuck toolholders
• 1.122-inch length of cut accommodates typical thread depth requirements for M10 fastener applications

Compatibility

Designed for use in CNC milling machines and machining centers equipped with helical interpolation capability and standard 0.375-inch collet or end mill toolholding systems. Suitable for M10x1.5 thread applications with a minimum nominal diameter of 10 mm.

Installation Notes

This tool must be run on a CNC machining center capable of helical interpolation — it cannot be used in a drill press or manual mill. Secure the shank fully into a balanced collet chuck or end mill holder and verify runout before cutting. Program feeds, speeds, and helix pitch according to the workpiece material and the tool manufacturer guidelines for carbide thread mills. Inspect the cutting edges before each use and replace the tool at first signs of chipping or coating wear to avoid thread form errors.
