Kennametal 3031737 Carbide Thread Mill Insert 12 Tpi

Product Description

The KENNAMETAL 3031737 is a carbide thread mill insert designed for internal UN thread milling applications. Built to insert style TM25 and manufactured in grade KC610M, this insert features a PVD-applied TiCN coating that provides wear resistance and thermal stability during threading operations. With 12 teeth per inch (TPI), it is engineered to cut precise internal UN-standard threads in a single pass or in programmed helical interpolation cycles. The insert measures 3.56 mm (approximately 0.14 inches) in thickness. At 0.008 pounds, it is a compact, precision tooling component suited for CNC machining centers and thread milling setups used by machinists and tooling specialists in production and job shop environments.

This insert is intended for internal thread milling of UN-standard threads at 12 TPI. It is applicable in metalworking environments where thread milling is preferred over tapping, particularly in difficult-to-tap materials or blind-hole applications. The TM25 insert style is suited for use in compatible Kennametal thread mill toolholders. Installation is typically performed by tool crib personnel or machinists setting up CNC machining centers for threading operations in ferrous and non-ferrous workpiece materials.

Key Features

• Insert style TM25 with KC610M carbide grade for wear resistance in threading applications
• PVD-applied TiCN coating for improved tool life and surface finish
• 12 TPI cutting geometry for internal UN-standard threads
• Non-conical insert profile for consistent thread form
• Lightweight at 0.008 pounds for easy handling during insert changes

Compatibility

Designed as an OEM-style replacement insert for use in compatible Kennametal TM25-series thread mill toolholders configured for internal UN threading at 12 TPI.

Installation Notes

This insert is installed by a qualified machinist or tool crib technician into a compatible thread mill toolholder. Always power down and lock out the machine spindle before changing inserts. Use the appropriate insert seating torque specifications provided by the toolholder manufacturer. Verify insert seating and thread form accuracy with a calibrated thread gauge before production runs.
