Carmex 16ER1.5ISOBMA Threading Insert 1.5mm Iso Carbide

Product Description

The CARMEX 16ER1.5ISOBMA is a solid carbide laydown threading insert designed for external ISO thread cutting at a 1.5 mm pitch. Built to the 16 ER insert style with a 60-degree included angle, it carries a PVD-applied TiAlN coating for heat resistance and extended tool life in demanding threading operations. The insert measures 3/8 inches inscribed circle and 0.143 inches thick, with a 0.0070-inch corner radius. Machinists and CNC operators install this insert in compatible laydown threading toolholders to produce right-hand external ISO metric threads across a broad range of workpiece materials.

This insert is rated for universal workpiece material compatibility, covering material codes H, K, M, N, P, and S. That range spans steels, stainless steels, cast irons, non-ferrous metals, high-temp alloys, and aluminum-family materials. It suits production threading on CNC lathes and turning centers in job shop, contract machining, and industrial manufacturing environments where ISO metric external threads are a routine requirement.

• 3/8 inches inscribed circle, 0.143 inches thick laydown-style geometry
• 0.0070-inch corner radius for controlled thread root form
• Manufactured to CE, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards

Compatibility

Designed as a direct-fit laydown threading insert for toolholders accepting the 16 ER insert style. Verify toolholder seat geometry and clamping system compatibility before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the tool turret or holder is locked out before seating or replacing the insert. Use the manufacturer-recommended torque driver for the clamping screw to avoid seat damage - do not overtighten by feel. Confirm insert orientation and seating before resuming any cutting cycle.
