The Mitutoyo standard type bore gage three-piece sets feature interchangeable anvils and provide an inside dimension measuring range of 18-150mm / 0.7-6in with an accuracy to 2µ / 0.00008in. The Mitutoyo standard-type bore gage set includes 26 interchangeable anvils, 10 spacers and 3 stems to measure a wide range of bore diameters with one Dial Indicator. A pendulum guide structure improves sliding the gage for measurements while a two-point contact system detects geometry anomalies such as oval-ness and taper.

The 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 molded carbide-tip type. Thus, they almost never scratch a workpiece. This model 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. The plunger stroke of flagship models has expanded from 1.2mm to 1.6mm, still maintaining the stated accuracy. The measurement accuracy of new models has improved by 50% or more compared with their predecessors. Optional extension rods are available for measuring deep holes.

The Mitutoyo inch reading dial indicator performs with excellent accuracy and reliability, and it is available in several graduations and ranges for use in the widest range of applications. The stem and spindle are constructed of hardened, high-strength steel, and the jeweled bearing provides wear resistance and low friction movements for smooth, precise operations. Secured adhesion between the frame and crystal, along with the use of an O-ring, protects the indicator against water and oil permeation via the front face. The crystal has a scratch and glare-resistant coating for clearer readings and better durability. The outer clamp and optional lifting lever can be attached to either side and can be easily installed or removed without the use of tools.
