"Universal" back plunger dial indicator




This high quality inch reading German-made Kafer back plunger indicator is the best of its kind. It has an 8 mm diameter stem which is 16.5 mm long (useful length). The bezel diameter is 40 mm and the smallest step is 28 mm in diameter. It can easily be used in standard indicator holders or fixtures of your own design. If the indicator needs to fit a 3/8" fixture, a simple stem adapter sleeve can be used (see page 133).


The dial indicator's range is .04 inches as seen on the close-up of the 40 mm Ø dial face.

Other Options: Back Plunger indicators by Starrett



Starrett makes a popular and relatively affordable model 196 back plunger indicator often found in automotive engine shops. While it is a poor cousin of the German indicator shown above, it may be exactly what you are looking for at a fraction of the price. You will have several different contact point options.

These indicators are difficult to repair and may have to be considered “throw-away” tools.

  • .001" graduations
  • .2" travel (range)

Because we are not authorized distributors for Starrett, we will direct your attention to the nemesis of all on-line retailers: Amazon. You will most likely reap discounts from 20% to 25% and will be assured that you receive a genuine Starrett indicator.
