JBO Thread Ring Gauge (GO) - BSP (G) - Left Hand - Tol. A - 2 1/2 x 11 S&E this reamer uses an intermediate

this reamer uses an intermediate precision carbide (k10) grade and features a left-hand spiral flute with right-hand cutting

The result is improved first-pass accuracy

reduces rework by giving an immediate pass/fail signal for in-process parts

H5 tolerance aligned with DIN 212-B: Ensures a precise bore size that fits closely with standard tooling

and anyone performing routine threaded-hole checks in manufacturing
