Mitutoyo Dial Bore Gage
Series 511

These dial bore gages have gaging heads with interchangeable anvils. Each bore gage comes supplied with a .0001" dial indicator and all the anvils required for the range of the tool. Spacers are included for small adjustments to the range. Roller guides on larger models keep the measuring head centered in the bore. The measuring contact is carbide. Accuracy is .0002"

Optional extension rods can be attached for reaching into deep bores (see below for ordering information). These are considerably less expensive than other imported dial bore gages and, most significantly, they're usually in stock. For replacement parts such as missing spacers and worn anvils, see page 72.
