Harvey Tool 16929-C3 Thread Mill M10x1.5 4 Flute Altin

Product Description

The HARVEY TOOL 16929-C3 is a solid carbide helical flute thread mill designed to cut M10x1.5 metric threads in both internal and external applications. With a 0.3000-inch cutting diameter, a 0.3125-inch (5/16 inch) shank diameter, and 4 flutes, this tool is built for rigid, high-efficiency thread milling on CNC machining centers. The AlTiN coating extends tool life in ferrous and high-temperature alloy materials by reducing heat buildup and resisting wear. Machinists and toolroom professionals rely on this geometry for precise, single-setup thread generation without the breakage risk associated with taps in difficult materials.

This thread mill is suited for use in job shops, production machining environments, and toolroom applications where M10x1.5 threads are required. Its helical flute design allows it to produce both internal and external threads, reducing the number of tools needed in a program. The 0.75-inch length of cut accommodates standard M10 thread depths, and the 3.0-inch overall length provides reach for typical workholding setups. It is used by machinists programming CNC mills for aluminum, steel, stainless, and similar machinable alloys.

Key Features

• Cuts M10x1.5 metric threads in both internal and external configurations from a single tool
• 4-flute helical geometry for smooth chip evacuation and consistent thread form
• Solid carbide construction delivers rigidity and dimensional stability under cutting loads
• AlTiN coating improves wear resistance and tool life in ferrous and high-heat materials
• 0.75-inch length of cut suits standard M10 thread depth requirements
• No coolant-through design — compatible with flood or mist coolant applied externally

Compatibility

Designed for use in CNC machining centers accepting a 5/16-inch round shank. Suitable for thread milling M10x1.5 metric threads in a range of machinable materials including aluminum, carbon steel, alloy steel, and stainless steel.

Installation Notes

Install this tool in a precision collet or end mill holder rated for the 5/16-inch shank diameter and verify runout before cutting. Thread milling requires a CNC controller capable of helical interpolation — confirm program compatibility before running. Secure the workpiece firmly to prevent vibration, which will degrade thread quality and shorten tool life. Follow the tool manufacturer's recommended speeds and feeds for the specific workpiece material and do not exceed the stated length of cut.
