Carmex 22ERN60BMA Threading Insert 60 Degree Solid Carbide

Product Description

The CARMEX 22ERN60BMA is a laydown threading insert designed for external partial profile thread cutting at a 60-degree included angle. Made from submicron solid carbide and finished with a PVD TiAlN coating, it delivers consistent thread form across a broad range of workpiece materials. The insert covers a pitch range of 3.50 to 5.00 mm (7 to 5 TPI) and is configured for right-hand external threading operations. With a 0.5000-inch inscribed circle and a thickness of 0.1870 inches, it seats in standard 22 ER style toolholders. This insert is installed and replaced by machinists and CNC turning technicians performing precision threading passes on lathes and turning centers.

This insert is suited for turning applications across a wide range of workpiece materials including steel, stainless steel, cast iron, nonferrous alloys, and high-temperature alloys, as indicated by universal material compatibility codes H, K, M, N, P, and S. It is appropriate for both production shop and job shop environments where external thread profiles in the 7 to 5 TPI range are required. The 22 ER insert style is a common laydown format used in standard turning toolholders, making it a direct drop-in for compatible tooling setups.

Installation Notes

Installation is performed by machinists using appropriate insert seating tools and torque wrenches sized for the toolholder clamping screw. Ensure the machine spindle is fully stopped and the turret is indexed away from the work zone before changing inserts. Inspect the toolholder pocket for chips or debris before seating the replacement insert to ensure proper contact and accurate thread form. Follow the toolholder manufacturer's clamping torque specifications for the 22 ER insert style.
