Buying Guide

Choose the right substrate

Carbide is standard for durability and heat resistance; confirm grade/coating (TiN, Tin, multilayer) to match your material and feed/speed needs

Match insert geometry to your operation

Wiper profiles and round or TPG/TPCN shapes change surface finish and chip control—pick geometries suited for finishing versus heavy stock removal

Consider coatings for material-specific performance

TiN or Tin coatings improve wear resistance for steel and general use, while dedicated aluminum inserts are formulated to reduce built-up edge on non-ferrous metals

Look for kits with holders or extra pieces

Multi-piece packs and included holders offer immediate usability and value for hobbyists and small shops that need several inserts on hand

Verify compatibility with your toolholder

Check insert size codes (e.g., TPG, TPCN, RCMT) and rake/seat dimensions to ensure they seat properly in your existing lathe or milling holders
