Carmex 27IRQ60P25C Threading Insert 5/8 Ic Internal Rh P25C

Product Description

The CARMEX 27IRQ60P25C is a laydown threading insert designed for internal right-hand thread cutting on CNC lathes and threading centers. It features a 60-degree included angle and a partial profile geometry suited for cutting unified and metric-equivalent thread forms across a range of 4.5 to 4 TPI. The insert is manufactured from solid carbide in the P25C grade (material grade C5) and carries a PVD-applied TiN coating for improved wear resistance and tool life. The 5/8-inch inscribed circle measures 0.6250 inches in diameter, and the insert thickness is 0.2510 inches. This insert is intended for use by machinists and CNC operators in production and job-shop environments.

This insert is suited for internal threading operations on a wide range of workpiece materials, including steel, stainless steel, cast iron, non-ferrous metals, high-temperature alloys, and other materials covered by ISO material codes H, K, M, N, P, and S. The P25C grade and TiN PVD coating make it a practical choice for universal applications where a single insert must handle varied materials or moderate cutting conditions. It is typically used in conjunction with a compatible 27IR-style laydown insert holder on CNC turning equipment.

Compatibility

Designed for use with 27IR-style laydown insert toolholders. The insert style code is 27IR and the MSC/manufacturer number is 27IR Q60. Compatible with internal threading applications across universal workpiece materials as defined by ISO material codes H, K, M, N, P, and S.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Before changing inserts, ensure the machine is powered down and all axes are fully stopped. Seat the insert firmly and evenly in the toolholder pocket before tightening the clamping screw to the toolholder manufacturer's specified torque. Verify thread form and pitch against a thread gauge before running a full production cycle.
