These extremely popular Mitutoyo dial bore gages have gaging heads with interchangeable anvils and carbide-tipped contacts. 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 .00008" and indication stability (which probably means repeatability - it's a new term for us) is .00004"
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.
