Carmex Carbide Threading Insert - ISO/METRIC - TiAlN Coated - 21I3.5ISO Centre Drill The hollow-ground geometry reduces rubbing

The hollow-ground geometry reduces rubbing near the bore

while the carbide construction provides wear resistance under high cutting speeds

ensuring parts fit precisely without over-sizing

This insert is built to support efficient workflows—from basic threading jobs to more complex components—by delivering consistent results

and secure clamping supports improved workflow

Carmex Carbide Threading Insert - ISO/METRIC - TiAlN Coated - 21I3.5ISO Centre Drill The hollow-ground geometry reduces rubbingA versatile collection of threading inserts, covering all common thread profiles. The inserts are available in 5 different lengths (from 12 mm to 40 mm), and depending on the length can handle pitches from 0. 5 mm 32 TPI to 6. 0 mm 4 TPI. Features: The inserts are double sided, i. e. have two cutting edges (except for BSPT NPT NPTF American Buttress API RD) For many thread profiles, the same insert can machine both internal & external applications
