The CARMEX 22IR6UNBMA is a solid carbide laydown threading insert designed for internal UN thread forms at 6 threads per inch. It features a TiAlN coating applied via PVD process, which extends tool life across a broad range of workpiece materials. The insert has a 0.5-inch inscribed circle, a thickness of 0.187 inches, and a 60-degree included angle. A 0.010-inch corner radius supports consistent thread profile accuracy. The submicron carbide grade BMA provides the edge toughness and wear resistance required for precision internal threading on CNC lathes and turning centers.
This insert is suited for internal threading operations on a wide range of materials, including steel, stainless steel, cast iron, nonferrous alloys, and high-temperature alloys, as reflected by its H, K, M, N, P, and S workpiece material codes. It is oriented for right-hand thread cutting and is appropriate for both production and job-shop environments where UN thread standards are required. Machinists and CNC operators working on threaded bores, nuts, couplings, and fittings will find this insert compatible with standard 22IR insert-style toolholders.
Designed for use in standard 22IR-style internal threading toolholders. Compatible with right-hand internal threading applications requiring a UN thread form at 6 TPI.
Installation and insert changes should be performed by a qualified machinist with the machine in a full stop and locked-out condition. Seat the insert firmly in the toolholder pocket and torque the clamping screw per the toolholder manufacturer specifications. Inspect the insert pocket for chips or debris before seating to ensure proper contact and repeatability. Verify thread pitch and hand orientation against the workpiece drawing before initiating the threading cycle.
