Kennametal 1937509 Carbide Turning Insert 80 Diamond Tialn

Product Description

The KENNAMETAL 1937509 is a CDHB-style carbide turning insert with a KC5010 manufacturer grade and a PVD-applied TiAlN coating. It features an 80-degree diamond insert shape with a 5/32-inch (0.1563 inch) inscribed circle and a corner radius of 0.0079 inches. The insert holds with a screw-on method and is designed for neutral-hand turning operations. With two cutting edges, a flat-top chipbreaker, and a 15-degree relief angle, this insert is suited for precision external turning where consistent chip control and edge integrity are critical. Licensed HVAC techs and machinists recognize the KC5010 grade as optimized for PVD coating adhesion on demanding workpiece materials.

This insert is intended for turning applications on steel, stainless steel, superalloys, and titanium, corresponding to ISO material codes P, M, and S. It is appropriate for light-to-moderate depth-of-cut passes, with a maximum depth of cut of 0.0492 inches (1.25 mm). The flat-top chipbreaker geometry and positive rake angle make it well-suited for finishing and semi-finishing passes in CNC turning centers and manual lathes where close tolerances are required.

• Two cutting edges per insert for cost-effective use
• Maximum depth of cut of 0.0492 inches (1.25 mm) suited for finishing and semi-finishing

Compatibility

Designed for use in CDHB-style screw-on turning toolholders. Primary workpiece material codes are P (steel), M (stainless steel), and S (superalloys and titanium). Secondary workpiece material codes include N, P, and S. Complies with ANSI and ISO insert standards.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the turret is locked before indexing or replacing inserts. Use the appropriate torque driver for the screw-on clamp screw to avoid stripping the insert pocket. Inspect the insert pocket seat for chips or debris before seating the new insert to ensure proper contact and prevent edge chipping.
