JBO Thread Plug Gauge - Trapezoidal Go-No/Go - Right Hand - 7H - Tr. 12 x 3 FHH This intermediate precision reamer is

This intermediate precision reamer is made from M2 high-speed steel and uses a taper shank

allowing stable cutting in deep pockets and grooves with minimal deflection

003 mm ensures hole sizes stay consistent across uses

tight-sized features that minimize finishing work and improve part accuracy across batches

Extended neck for enhanced reach and stability: The extended neck length provides clearance for deep pockets and complex setups while maintaining cutting accuracy and minimizing deflection

JBO Thread Plug Gauge - Trapezoidal Go-No/Go - Right Hand - 7H - Tr. 12 x 3 FHH This intermediate precision reamer isThe JBO Thread Plug Gauge is a precision inspection tool designed to verify trapezoidal threaded holes quickly and reliably. Built for manufacturers, automotive shops, and aerospace suppliers, it provides a clear go no go verdict on whether threads meet the required standard and size. With its right hand orientation and 7H tolerance (Tr. 12 x 3), this gauge supports accurate, repeatable measurements in demanding environments. Designed with meticulous
