Carmex 16IR32UNC-5/P30 Threading Insert 32 Tpi Solid Carbide

Product Description

The CARMEX 16IR32UNC-5/P30 is a solid carbide laydown threading insert designed for cutting internal UN-standard threads at 32 threads per inch (TPI). It features a 60-degree included angle and a 3/8-inch inscribed circle, making it a precision tool for right-hand internal threading operations on a wide range of workpiece materials. The uncoated solid carbide construction provides consistent performance across universal material groups. This insert is installed and used by machinists and tool and die professionals working on CNC or manual lathes performing precision thread forms.

This insert is suited for internal threading operations on workpiece materials spanning multiple material groups, including steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys. It is appropriate for both production and maintenance machining environments where accurate UN thread profiles are required. The right-hand cutting configuration covers the most common internal threading applications in general-purpose and precision machining.

Key Features

• Solid carbide uncoated construction for consistent dimensional accuracy on universal material grades
• 32 TPI cutting profile for UN internal thread standard
• 60-degree included angle matches standard UN thread form geometry
• 3/8-inch inscribed circle with 0.146-inch thickness fits standard 16IR toolholder pockets
• Right-hand cutting orientation for standard internal thread direction
• C-5 material grade and P30 manufacturer grade suitable for a broad range of workpiece materials
• Certified to CE, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards

Compatibility

Designed as a direct-fit replacement or standard insert for 16IR-style laydown threading toolholders requiring a 3/8-inch inscribed circle seat. Compatible with workpiece material codes H, K, M, N, P, and S as classified under standard ISO material groupings.

Installation Notes

Installation is performed by a qualified machinist. The insert seats into a 16IR-style toolholder pocket and is secured per the toolholder manufacturer torque and clamping specifications. Ensure the machine spindle is fully stopped and all motion has ceased before changing or inspecting inserts. Handle solid carbide inserts carefully to avoid chipping on cutting edges prior to use.
