Carmex Small Indexable Carbide Threading Insert - Full Profile ISO - T8 - M10 x 1.25

A compact, full-profile carbide threading insert from Carmex designed for internal threads with ISO profiles. This T8 insert targets M10 x 1.25 threads and a broad range of ISO/UN internal-thread pitches, delivering precise, repeatable results in small bores.

• Insert size: T8
• Profile: Full-profile ISO; internal-threads-only design
• Thread size & compatibility: Internal threads per ISO and UN profiles; pitches from 0.5 mm (32 TPI) to 3.0 mm (8 TPI); suitable for M10 x 1.25
• Minimum bore diameter: 8.0 mm / 0.31 in
• Material & coating: Carbide Grade BLU with triple-layer PVD coating (sub-micron) for stainless steels, cast iron, titanium, non-ferrous metals, and most high-temperature alloys (M10–M20, K05–K20, N10–N20, S10–S20)
• Usage: Internal threads only; indexable insert for quick edge replacement

This insert helps you achieve clean, accurate internal threads with reduced tool downtime. The BLU PVD coating extends edge life across a variety of materials, including stainless steels, cast iron, titanium, and many high-temperature alloys, enabling fewer insert changes and more consistent performance. The compact T8 size fits tight bore applications, while the wide pitch range lets you tackle both fine and coarse internal threads without swapping tools. Its full-profile ISO geometry provides stable cutting action and reliable thread formation, supporting consistent tolerances and surface finish in gears, housings, bearing caps, and other internal-threaded components.
