Meet the Asimeto Ring Hole Gauge H7, 675 Series — a precision tool engineered to measure the diameter of ring-shaped holes with H7 tolerance. It’s a reliable choice for machinists, toolmakers, and quality-control professionals who demand tight, repeatable bore checks on small apertures.

• Nominal size: 3 mm ring hole gauge designed for precise checks of small-diameter holes
• Tolerance: H7 close-fit tolerance ensures repeatable measurements between gauge and hole
• Series: 675 Series, a line dedicated to high-accuracy hole gauging
• Construction: precision-machined metal with a durable, corrosion-resistant finish
• Design: ring-shaped form for easy insertion and consistent readings from multiple angles
• Applications: ideal for QC workflows, fixture checks, and assembly tolerancing of ring holes in mechanical parts

This gauge helps you confirm bore readiness quickly and reliably, reducing guesswork and the risk of misfits in production or repair work. With a close H7 fit, parts slide into tolerance more predictably, enabling smoother assemblies, fewer rework cycles, and better overall part quality. Built for daily workshop use, the Asimeto 675 Series ring hole gauge combines precision with practicality, making it a staple tool in any precision machining or quality-control environment.
