Buying Guide

Match insert grade to material

Choose inserts with coatings and grades suited to the workpiece—TiN or multilayer coatings for steels, and tougher grades for stainless or hardened alloys

Pick the right geometry

Wiper, round, and T-shape geometries affect surface finish and feed rates; select geometry based on desired finish and chip control

Check compatibility with holders

Confirm insert size and pocket type (e.g., DCMT, TPG, RCMT) match your toolholder or boring bar before buying

Consider coated vs uncoated

Coatings like TiN or multilayer can extend life and improve performance on abrasive materials compared with uncoated carbide

Buy packs that fit usage

Smaller 10–21 piece packs suit hobbyists and light production, while larger or mixed kits work better for varied tooling needs
