Carmex 22IRN60BMA Threading Insert 60 Degree Carbide

Product Description

The CARMEX 22IRN60BMA is a solid carbide laydown threading insert designed for internal partial profile threading at a 60-degree included angle. Manufactured from submicron-grade carbide and finished with a PVD-applied TiAlN coating, this insert handles a thread pitch range of 7 to 5 TPI (3.50 to 5.00 mm) in right-hand orientation. The 1/2-inch inscribed circle and 0.187-inch thickness conform to standard 22IR toolholder pockets. It is installed by CNC machinists and tool-and-die professionals performing precision internal thread-cutting operations across a wide range of workpiece materials.

The 22IRN60BMA is suited for internal threading applications across universal workpiece material categories including steel, stainless steel, cast iron, non-ferrous metals, high-temperature alloys, and aluminum. The BMA grade designation reflects CARMEX submicron carbide substrate engineering optimized for consistent thread form and tool life across mixed production environments. Typical applications include threading bores in turned components, fittings, couplings, and hydraulic manifolds where a 60-degree thread profile and right-hand cut are required.

Key Features

• Solid carbide submicron substrate with PVD TiAlN coating for extended wear resistance
• 60-degree included angle for standard internal partial profile thread forms
• Right-hand cut, 7-5 TPI range (3.50 to 5.00 mm pitch)
• 1/2-inch inscribed circle fits standard 22IR toolholder pockets
• Universal material grade compatibility: steel, stainless, cast iron, non-ferrous, superalloys, aluminum
• Meets CE, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards

Compatibility

Designed to seat in 22IR-style laydown threading toolholders accepting a 1/2-inch inscribed circle insert with 0.187-inch thickness and a 60-degree geometry.

Installation Notes

Installation should be performed by qualified machinists following the toolholder manufacturer torque and clamping specifications. Ensure the machine spindle is fully stopped and the CNC program is in a safe state before indexing or replacing inserts. Inspect the toolholder pocket for chips or wear before seating the insert to maintain thread form accuracy. Handle carbide inserts with care to avoid chipping the cutting edge prior to use.
