Kennametal 4175936 Threading Insert NTK2R KCU10 Carbide

Product Description

The KENNAMETAL 4175936 is a carbide threading insert designed for precision thread-cutting operations on both internal and external thread forms. Running the KCU10 grade with a PVD-applied AlTiN finish, this insert handles partial profile 60-degree thread standards across a wide pitch range: 0.60 to 1.75 mm (14 to 44 TPI) for external threads and 1.00 to 2.00 mm (12 to 24 TPI) for internal threads. It is a right-hand insert in the Top Notch series, sized at insert size 2, with a corner radius of 0.08 mm (0.0031 inches) and a thickness of 5.56 mm (0.219 inches). Machinists and CNC programmers working in production and job-shop environments rely on this insert for consistent thread geometry.

This insert is suited for threading operations on a variety of materials where AlTiN coating provides heat resistance and extended tool life. It fits standard Top Notch toolholders configured for NTK-style inserts. Typical applications include threading on lathes and turning centers in both internal and external configurations, covering metric and unified thread pitches within the stated ranges. It is appropriate for both light and medium production threading where a partial profile insert is specified.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine before seating or replacing the insert. Ensure the toolholder pocket and clamping screw are clean and free of chips before placing the insert. Follow the toolholder manufacturer's clamping torque specifications and verify insert seating before resuming cuts.
