VCOIL Plug Gauge (D/E) - UNC (STI) - Heli Coil Gauge - Right Hand - 2B - 3/4 x 10 ER Collet Chucks Right-hand thread: designed to match

Right-hand thread: designed to match standard right-hand threaded fasteners

and complex contours where reach and precision matter

helping teams speed up inspections without sacrificing accuracy

while the BS 328/4 specification underpins its suitability for demanding reaming tasks

Tapered neck for enhanced rigidity and reach: The tapered geometry increases rigidity and minimizes deflection during deep groove machining
