• Used for quick and accurate setting of dial bore gages, Holtest, and inside micrometers.
• Actual diameter is marked in 0.001 mm increments. (Measuring position of dimension is the center of the height T.)

*1 Actual diameter is marked in 0.001 mm increments. (Dimension measuring position is the center of the height T.)
*2 Cylindricity is defined as per JIS B 0621 Definitions and designations of geometrical deviations, Section 4.4 “Cylindricity.” Cylindricity is measured using three cross-sections between the top and bottom face of a ring, namely, close to the face near each side and the center.
