Bowers SXT4000M-BT XT500 Large Diameter Digital Bore Micrometer Set, Range 400-500mm, Resolution 0.001mm, Bluetooth, with Setting Ring

The Bowers SXT4000M-BT is a set version of the Bowers XT500 large diameter 3-point bore micrometer, designed for internal diameters between 300 and 500 mm. A constant-force digital readout keeps the measuring pressure the same throughout the measurement, and radiussed tool-steel anvils give optimum centring in the part. Anvil sets come in 25 mm steps, each made to its exact toleranced size; the 300-325 mm anvils are the master reference set used to set the gauge in the 300 mm ring, so the other anvil sets can be fitted without re-setting.

Supplied with a 300 mm setting ring, which sets the gauge for the full 300-500 mm range.
