The combination of carbide hardiness
Through-Coolant Hollow Design: Allows coolant to flow through the centre
Wide size range (2–16 mm) in one set: Includes 15 precision ER25 collets from 2 mm to 16 mm
Carbide-tipped for long life: The K10 carbide tip resists wear and keeps cutting edges sharp longer than standard high-speed steel
from production shops to hobbyist workshops
JBO Thread Ring Gauge (NoGo) - UNF - Right Hand - 2A - No. 1 x 72 Morse Taper Adaptor The combination of carbide hardinessThe JBO Thread Ring Gauge (NoGo) is a precision tool for verifying external UNF threads. Designed for manufacturing, automotive, and aerospace environments, it is ideal for engineers, inspectors, machinists, and quality teams. It checks right hand UNF threads at size No. 1 x 72 and class 2A, with a No Go segment that clearly flags non conforming threads for fast, decisive quality control. Crafted from hardened steel, this gauge is built for daily use,
