Buying Guide

Choose the right coating

Coatings like TiN, tin, or multilayer protect carbide inserts and influence wear resistance and workpiece finish—select a coating suited to your material and feed rates

Match insert geometry to the operation

Wiper-style geometries and TPG/WNMG shapes improve surface finish for finishing passes while round or RCMT styles are better for interrupted cuts and roughing

Consider bundle value

Kits that include multiple inserts and a compatible holder or boring bar often deliver better immediate value for setup and replacement needs

Check grade and substrate

Carbide grade and substrate affect toughness and heat resistance—look for grades appropriate for alloyed steels, stainless, or cast iron depending on your workpieces

Verify machine and size compatibility

Confirm insert size codes (e.g., TPG, WNMG, RCMT) and holder compatibility with your lathe or boring bar to avoid fitment issues
