VCOIL Plug Gauge (D/E) - UN (STI) - Heli Coil Gauge - Right Hand - 2B - 1.1/8 x 8 Hydraulic Expansion Chucks Hand-screw go end: The go

Hand-screw go end: The go end must screw into the thread by hand without using excessive force

Left-hand spiral flute & right-hand cutting: This combination provides stable cutting

minimizing deflection and delivering repeatable performance in demanding workloads

high-quality threaded surfaces with fewer reworks and longer tool life

and promotes longer tool life through better wear resistance and easier chip removal
