Mitutoyo Test Indicator Attachments

Made by Mitutoyo, specifically for their own brand of test indicator. Most of these attachments will also fit other manufacturers' models. If you would like to see Swiss made indicator attachments, which will also fit most Mitutoyo models, please refer to page 36.

  • If you are specifically looking for contact points, you will find them listed on page 21.

Why do we keep writing "most models?" Because Mitutoyo makes one unusual indicator called "Pocket Type." It has a tubular body and roughly (very roughly) resembles the Starrett Last Word indicator. It does not have any dovetails so the regular stems and attachments have no way of being attached. You will have to be quite specific when ordering attachments for these Pocket Type indicators.

The swivel clamp attaches to the dovetails of all indicators which have dovetails. This includes Starrett, BesTest, Compac, Interapid, Fowler, and even generic Chinese indicators. There are two holes in the clamp, of different diameters, and the clamp is tightened with a single thumb screw.

For "pocket type" test indicators

The universal holder for the pocket type indicators such as model 513-518 (and the older 513-118) screws into the end of the indicator. It is not designed for a dovetail. A ball joint allows it to swivel to a desired position.
