Carmex 3/8EXRHG60MXC Threading Insert 3/8 Ic 60 Deg 14-8 Tpi

Product Description

The CARMEX 3/8EXRHG60MXC is a laydown-style external threading insert engineered for right-hand partial-profile 60-degree thread cutting. Manufactured from solid micrograin carbide and finished with a PVD-applied TiN coating, this insert is built for consistent thread form across a broad range of workpiece materials. It carries a 3/8 inch inscribed circle, a thickness of 0.146 inches, and covers a thread pitch range of 14 to 8 TPI (1.75 to 3.00 mm pitch). The MXC/GOLD grade designation indicates a micrograin carbide substrate suited for demanding threading operations on both ferrous and non-ferrous materials. Licensed machinists and CNC turning specialists are the primary users of this insert.

This insert is intended for external threading operations on CNC lathes and turning centers. It accommodates a wide range of workpiece materials, including steels, stainless steels, cast irons, non-ferrous alloys, and heat-resistant superalloys, corresponding to material codes H, K, M, N, P, and S. The 60-degree included angle makes it suitable for standard Unified and ISO metric thread profiles. Typical applications include threading turned components in production and job-shop environments where tool change repeatability and coating durability are priorities.

• Right-hand laydown insert geometry for use in standard 16ER-compatible toolholders
• Compliant with CE, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards

Compatibility

Designed for use in 16ER-style laydown threading toolholders. Compatible with workpiece materials assigned codes H, K, M, N, P, and S, covering cast iron, stainless steel, steel, non-ferrous alloys, and heat-resistant superalloys.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Before indexing or replacing inserts, ensure the machine spindle is stopped and the tool is clear of the workpiece. Seat the insert fully in the toolholder pocket and torque the clamping screw according to the toolholder manufacturer specifications. Verify insert seating and alignment before resuming cutting operations.
