Simple - After setting the gage on a known size, production grinding is a breeze! Simply grind until the indicator returns to zero. There is no need to stop the machine to check size, and all guesswork is eliminated. A spring mounting provides sensitive support during grinding, and retracts the gage out of the way during part loading. Installation is also fast and easy. Order one today, and start gaging tomorrow.
