Carmex 3/8INRHA60MXC Threading Insert 3/8 in Ic Carbide Tin

Product Description

The CARMEX 3/8INRHA60MXC is a solid carbide laydown threading insert designed for right-hand internal threading operations. It cuts a partial profile 60-degree thread form and covers a wide thread range of 48 to 16 TPI, equivalent to a 0.50 to 1.50 mm pitch. The insert features a 3/8 inch inscribed circle and a thickness of 0.146 inches. A PVD-applied TiN coating improves surface hardness and wear resistance during threading cycles. This insert is used by machinists and CNC operators running internal threading toolholders on lathes and turning centers where consistent thread form and tool life are priorities.

This insert is suited for internal threading applications across a broad range of workpiece materials, including steel, stainless steel, cast iron, non-ferrous alloys, and high-temp alloys, reflected by its universal material compatibility codes H, K, M, N, P, and S. It is appropriate for both light production and high-volume turning environments where a single insert geometry needs to handle varied materials without frequent changeovers. The laydown seating style ensures repeatable indexing in compatible 16IR-style toolholders.

Key Features

• Solid carbide substrate with PVD TiN coating for extended wear life
• Right-hand internal partial profile 60-degree thread form
• Covers 48 to 16 TPI (0.50 to 1.50 mm pitch) in a single insert
• 3/8 inch inscribed circle, 0.146 inches thick - 16IR insert size code
• Universal workpiece material compatibility: steel, stainless, cast iron, non-ferrous, and superalloys
• Meets CE, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards

Compatibility

Designed for use in 16IR-style internal threading toolholders that accept laydown threading inserts with a 3/8 inch inscribed circle. Compatible with CNC lathes and turning centers running right-hand internal threading cycles across universal workpiece material classes (H, K, M, N, P, S).

Installation Notes

Installation is performed by machinists or CNC tooling technicians. Power down or lock out the machine spindle before indexing or replacing the insert. Use the correct torque wrench and manufacturer-specified clamping screw to secure the insert in the pocket - do not overtighten by hand. Verify insert seating and tool nose radius clearance before resuming threading cycles.
