Carmex 1/4EXRHA60MXC Threading Insert 60 Degree 48-16 Tpi

Product Description

The CARMEX 1/4EXRHA60MXC is a laydown-style threading insert designed for right-hand external thread turning on CNC lathes and manual threading applications. Built from micrograin solid carbide with a PVD-applied TiN coating, this insert delivers consistent thread form across a wide TPI range of 48 to 16 (0.50 mm to 1.50 mm pitch). The 60-degree included angle produces a partial profile external thread, making it suitable for unified and metric thread forms. With a 1/4 inch (0.2500 inch) inscribed circle and a thickness of 0.1270 inches, it seats into standard 11 ER-style toolholders. Machinists and tool-and-die professionals use this insert for production threading on a broad range of workpiece materials.

This insert is rated for universal workpiece material compatibility, covering material grades designated H, K, M, N, P, and S. That range includes carbon steels, stainless steels, cast iron, non-ferrous metals, aluminum alloys, and heat-resistant superalloys. It is well suited for job shops and production environments where a single threading insert must handle varied materials without frequent grade changes. Typical applications include threading shafts, couplings, fittings, and fastener blanks on turning centers.

Key Features

• PVD TiN coating reduces friction and extends tool life across universal workpiece materials
• 60-degree partial profile covers 48 to 16 TPI (0.50 mm to 1.50 mm pitch) in a single insert
• Right-hand external threading geometry for standard OD thread turning
• 11 ER insert style seats directly into compatible laydown threading toolholders
• Certified to CE, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards

Compatibility

Designed to seat in standard 11 ER-style laydown threading toolholders. Compatible with workpiece materials across universal grades H, K, M, N, P, and S as defined by ISO cutting material classification.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer to avoid seat damage or insert rocking. Verify insert seating and clearance before initiating a threading pass.
