Mitutoyo 511-921-20 Dial Bore Gauge Gauge Set, 3 piece

The Mitutoyo dial bore gauge set measures diameter ranging between 18mm and 150mm and depth of 100mm and 150mm. This bore gauge has 50% more accuracy than its predecessors. Its new carbide-ball contact point and anvil tip have increased abrasion resistance compared with the steel ball type and better surface roughness compared with the moulded carbide-tip type. This gauge reduces the influence of heat from the operator’s hand by 50% by increasing the grip size and making the grip hollow-structured, thereby retaining high accuracy measurement.
