JBO Thread Plug Gauge (NoGo) - Metric Fine - Left Hand - 6H - M70 x 2 Face Mill Arbors it uses intermediate precision carbide

it uses intermediate precision carbide (K10) and a left-hand spiral flute with right-hand cutting to produce consistent bore sizes in demanding materials

Metric fine precision for reliable thread checks: Specifically sized for metric fine threads (M60 x 1

Reach: Extended length for accessing deep pockets and complex contours with ease

while right-hand cutting preserves predictable hole size and surface finish

Corner Radius for Durability and Finish: The corner-radius profile preserves geometry in tight features

JBO Thread Plug Gauge (NoGo) - Metric Fine - Left Hand - 6H - M70 x 2 Face Mill Arbors it uses intermediate precision carbideThe JBO Thread Plug Gauge (NoGo) Metric Fine Left Hand 6H M70 x 2 is a precision tool designed to verify metric fine threaded holes. It supports inspectors, machinists, and quality teams by delivering reliable go no go checks to confirm holes meet exact standards for M70 x 2 threads. With a left hand orientation and 6H tolerance, it is tailored to your metric fine threading workflow and ensures consistent inspection results. Metric Fine NoGo design:
