About the Mitutoyo 516-535-56
Grade K gauge blocks sit between Grade 0 laboratory blocks and everyday toolroom sets — accurate enough to calibrate working comparators and fixed gauges, but priced and built for frequent handling rather than reference-only use. The 87-piece set covers a wide combination range for building stacked dimensions in 0.001 mm/0.0001" increments.
Popular in calibration departments that need one comprehensive set to service both incoming inspection gauges and machine-tool setting work, without reserving a Grade 0 set purely for that purpose.
