VCOIL Plug Gauge (D/E) - UN (STI) - Heli Coil Gauge - Right Hand - 2B - 1.1/8 x 8 Hydraulic Expansion Chucks and promotes longer tool life

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

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

BMK-grade carbide for durability: Premium carbide resists wear and maintains sharpness for longer tool life

helping inspectors identify non-conforming threads at a glance and reduce inspection time and rework

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

VCOIL Plug Gauge (D/E) - UN (STI) - Heli Coil Gauge - Right Hand - 2B - 1.1/8 x 8 Hydraulic Expansion Chucks and promotes longer tool lifeThe VCOIL Plug Gauge (D E) UN (STI) Heli Coil Gauge is a precision go no go thread limit gauge designed for validating Helicoil inserted threads to the UN (STI) standard. Built for technicians and quality teams, it delivers fast, reliable pass fail feedback on threaded holes. Go No Go Thread Limit Gauge: Combines go and no go checks in a single tool to verify thread dimensions against ANSI ASME standards. ANSI ASME Compliance: Manufactured and
