It is suitable for processing threads in steel, stainless steel, cast iron, and other materials.
Groove threading inserts for lathe Features
● The triangular boss design effectively controls chip flow and accommodates machining methods such as radial and side feed.
● The curved surface design increases heat dissipation, prevents crater wear, and effectively extends tool life.
● The large chip flute design prevents chip accumulation during internal threading.
● Available in sizes 08, 11, 16, and 22.
Comparison of cutting life of competitors
Comparison of tool life between GME and Competitor A. Under identical machining conditions, GME's tool life reached 110 workpieces per tool, while Competitor A's tool life was only 95, a 16% improvement. This fully demonstrates GME's advantages in durability and machining efficiency.
