Carmex 16ER3.0ISOBXC Laydown Threading Insert Solid Carbide

Product Description

The CARMEX 16ER3.0ISOBXC is a solid carbide laydown threading insert designed for external ISO threading operations on CNC lathes and turning centers. It carries a 3.0 mm pitch, a 60-degree included angle, and a 3/8 inch (0.375 inch) inscribed circle, making it a standard-size insert for right-hand external thread cutting. The BXC manufacturer grade features a TiN-coated, PVD-applied surface that extends cutting edge life across a wide range of workpiece materials. Machinists and CNC operators install this insert into compatible 16 ER-style toolholders for precise, repeatable thread profiles.

This insert is suited for external ISO metric threading on turning and machining centers in both production and job-shop environments. The universal primary workpiece material classification covers cast iron, non-ferrous metals, stainless steel, general steel, and heat-resistant alloys, identified by material codes H, K, M, N, P, and S. It is appropriate for light to medium threading passes where consistent thread form and tool life are priorities. The 16 ER insert style is a common format used in standard laydown threading toolholders across the industry.

Key Features

• Solid carbide substrate for rigidity and wear resistance in threading applications
• PVD-applied TiN coating extends edge life and reduces built-up edge
• 3.0 mm ISO pitch with 60-degree included angle for standard metric thread profiles
• Right-hand cut, external thread orientation
• 3/8 inch inscribed circle (0.375 inch) in the 16 ER insert style
• Universal material compatibility across steel, stainless, cast iron, non-ferrous, and superalloy workpieces
• Manufactured to CE, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards

Compatibility

Designed as a direct-fit replacement for 16 ER-style laydown threading toolholders accepting a 3/8 inch inscribed circle insert with a 3.0 mm ISO pitch. Confirm toolholder seat geometry and pocket dimensions before installation.

Installation Notes

This insert is installed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench and insert screw specified by the toolholder manufacturer - do not overtighten the clamping screw, as this can fracture the carbide body. Inspect the toolholder pocket for wear or debris before seating the insert.
