4Piece Telescoping Hole Gauge Set Adjustable NickelPlated Internal Diameter 314mm Precision Measuring Tool Description

Hardened spherical measuring faces provide accurate readings and long tool life for hole and bore measurements. Tool adjustment shaft with a satin finish ensures smooth operation and repeatable setup. Hole gauge design supports reliable clearance checks across various holes. Extralong diameter measuring tool reaches deep and shallow holes, slots and similar workpieces; ball gauge included for quick diameter checks. Four sizes of gauges are supplied in a fitted case, micrometer included for precise sizing. Small bore gauges feature fully hardened gaging surfaces to withstand repeated use and maintain accuracy. Practical applications: Check bore and hole diameters in engine blocks, housings, and other precision parts during setup or quality control. Measure deep and shallow holes and slots in tooling, fixtures, and machinery components. Perform quick go/nogo checks on small bore dimensions to verify tolerances in manufacturing and inspection workflows.
