Kennametal 3031735 Carbide Thread Mill Insert 16 Tpi

Product Description

The KENNAMETAL 3031735 is a carbide thread mill insert designed for internal UN thread milling operations. Manufactured to the KC610M grade, this insert features a TiN/TiCN/TiN multilayer PVD coating applied via physical vapor deposition, which enhances wear resistance and extends tool life in demanding threading applications. At 3.56 mm (0.14 inches) thick and 0.1 pounds, this is a compact, precision-ground insert suited for thread milling on CNC machining centers. The TM25 insert style is specific to compatible Kennametal thread mill toolholders. Licensed machinists and CNC operators install this insert as a replaceable cutting element within a modular thread milling system.

This insert is intended for internal thread milling to UN thread standards at 16 teeth per inch. It is suited for use in precision machining environments including job shops, aerospace component manufacturing, and general industrial CNC operations where repeatable internal thread quality is required. The PVD TiCN coating makes it appropriate for a range of workpiece materials including steel and cast iron. This is a single-insert package with a minimum order quantity of 2 units.
