Carmex 08IRA60BXC Threading Insert 3/16 Ic 48-16 Tpi

Product Description

The CARMEX 08IRA60BXC is a solid carbide laydown threading insert designed for internal thread cutting applications. It produces a 60-degree partial profile thread and covers a range of 48 to 16 threads per inch, making it suitable for a wide variety of threading tasks on a single insert. The insert features a TiN finish applied via PVD coating process, which improves wear resistance and tool life. With a 3/16-inch inscribed circle and a right-hand cutting orientation, this insert fits standard laydown-style internal threading toolholders used in CNC turning operations. Machinists and tool-room operators working on precision threaded bores rely on this insert for consistent, repeatable thread form.

This insert is rated for universal workpiece material compatibility, including ferrous metals, stainless steels, cast irons, non-ferrous materials, high-temp alloys, and plastics. It is well suited for CNC lathe and turning center operations where internal threads must be cut across a broad range of pitches without changing inserts. Typical applications include threaded bore production in components for general manufacturing, aerospace, and industrial equipment where thread quality and surface finish are critical.

Key Features

• Solid carbide construction with PVD-applied TiN coating for extended wear resistance
• 60-degree included angle for standard unified and metric partial profile internal threading
• Covers 48 to 16 TPI range, reducing insert changeovers across multiple thread sizes
• Right-hand cutting orientation for standard internal thread applications
• 3/16-inch inscribed circle fits common laydown internal threading toolholders
• Universal material grade BXC rated for steel, stainless, cast iron, non-ferrous, and high-temp alloys

Compatibility

Designed for use in laydown-style internal threading toolholders accepting an 08 IR insert size with a 3/16-inch inscribed circle. Compatible with workpiece material codes H, K, M, N, P, and S as designated by manufacturer grade BXC.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the turret is in a safe index position before changing inserts. Seat the insert firmly and evenly in the toolholder pocket to prevent movement during cutting. Verify clamp torque per toolholder manufacturer specifications before beginning any threading pass.
