Carmex 16IR0.5ISOP30 Threading Insert Iso 0.5mm Solid Carbide

Product Description

The CARMEX 16IR0.5ISOP30 is a solid carbide laydown threading insert designed for internal ISO thread cutting on CNC lathes and threading machines. Manufactured to P30 grade with a C5 material grade, this uncoated insert handles right-hand internal threading at a 0.5 mm pitch. The 3/8-inch inscribed circle (0.375 inches) and 0.146-inch thickness conform to standard 16IR toolholder pockets, making it a direct fit for compatible boring bars and internal threading holders. Solid carbide construction provides rigidity and edge retention in steel and general-purpose turning applications where the P30 grade is rated.

This insert is suited for internal threading operations in steel and similar P-grade materials on CNC or manual lathes. The ISO thread standard and 0.5 mm pitch make it applicable to metric thread profiles in production and repair environments. It is typically installed by machinists and CNC setup technicians working on medium-duty threading operations. The uncoated finish is preferred in applications where coating adhesion could interfere with fine thread form accuracy or where regrinding is considered.

Key Features

• Solid carbide construction for rigidity and consistent edge performance
• P30 manufacturer grade and C5 material grade rated for steel threading
• 0.5 mm pitch ISO internal thread form
• Right-hand cut orientation
• Uncoated finish for precise thread form and predictable tool wear
• 3/8-inch inscribed circle fits standard 16IR toolholder pockets

Compatibility

Designed to seat in standard 16IR internal threading toolholders and boring bars that accept laydown-style threading inserts with a 3/8-inch inscribed circle and 0.146-inch thickness.

Installation Notes

Installation is performed by qualified machinists following standard insert-seating procedures for laydown threading inserts. Power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key to the toolholder manufacturer's recommended seating method without over-torquing the clamping screw. Verify insert orientation and thread hand before resuming cuts.
