Buying Guide

Match insert geometry to cut

Choose wiper, T-shape, round or triangular geometry based on finishing, roughing or internal boring needs to improve surface finish and tool life

Check coating and substrate

Prefer TiN or multilayer coatings on carbide for abrasion resistance and cooler cutting when machining steel, aluminum or mixed materials

Confirm size and holder compatibility

Verify insert code (e.g., TPG, APKT, RCMT) matches your toolholder and lathe setup to avoid fitment and clamping issues

Pick grade for your material

Select tougher grades for interrupted cuts and harder steels and tougher-coated grades for aluminum or finishing passes to reduce built-up edge

Buy sets for consistent geometry

Purchasing 10-piece sets or matched holder kits ensures uniform cutting geometry and simple indexable replacement during production runs
