Harvey Tool 986640-C6 Thread Mill 10-24 to 10-36 Solid Carbide

Product Description

The HARVEY TOOL 986640-C6 is a single profile thread mill designed for cutting both internal and external threads in the 10-24 to 10-36 range, spanning 24 to 36 TPI. Built from solid carbide and finished with an AlTiN Nano coating, it delivers extended tool life in demanding materials including stainless steels, hardened steels, and high-temperature alloys. The 5-flute geometry supports efficient chip evacuation and stable cutting action. With a 0.135-inch cutting diameter and a 0.086-inch neck diameter, this tool handles tight-clearance bores where standard threading tools cannot reach. Machinists and CNC programmers working in aerospace, medical, and general precision machining environments will find this tool suited to high-accuracy thread applications.

This thread mill is intended for use in CNC machining centers capable of helical interpolation, which is the standard method for single profile thread milling. It covers the full Number 10 thread range, making it practical for shops that thread both 10-24 and 10-36 fastener holes with a single tool. The internal and external threading capability reduces tooling inventory. Typical applications include threaded holes and bosses in aluminum, titanium, and ferrous alloys where thread quality and positional accuracy are critical.

Key Features

• Covers 10-24 to 10-36 thread range, 24 to 36 TPI, in a single tool
• Machines both internal and external threads via CNC helical interpolation
• Solid carbide construction for rigidity and wear resistance
• AlTiN Nano coating improves heat resistance and tool life in hard and abrasive materials
• 5-flute design promotes chip evacuation and surface finish quality
• Narrow 0.086-inch neck diameter enables access to tight-clearance threading operations

Compatibility

Designed as a single profile thread mill for CNC machining centers capable of helical interpolation, suitable for cutting Number 10 series internal and external threads from 24 to 36 TPI in a range of workpiece materials.

Installation Notes

Thread milling requires a CNC machine with helical interpolation capability; confirm your control and CAM post support thread milling cycles before use. Secure the 0.25-inch shank in a precision collet or end mill holder and verify runout before cutting. Program the helical path to match the target thread pitch and direction. Do not use this tool in manual or rigid-tapping applications.
