Although these tool inserts are categorized as M-class, the flank near the cutting edge is polished and the chip breaker is configured at a large rake angle to exhibit superior cutting performance equivalent to that of fully polished tools. Thus, these tools ensure high-quality, low-cost thread cutting with minimal amount of burrs left at the thread edges and very little peeling of the flank faces.
Use of “modified flank infeed cutting*” with a protruded 3D mold breaker ensures efficient chip disposal and dramatically reduces cutting edge fracture, thereby further extending the tool’s service life.
A lineup of 110 types of indexable inserts has been created. These include general purpose inserts without a flat cutting edge, as well as ones with a flat cutting edge that can meet the needs for cutting metric screw threads, unified screw threads, tapered pipe threads, and other threads complying with various screw specifications. These products can be used for thread cutting in a wide variety of industries, from general industrial machines to aerospace.
