Test Indicator Holders

Test indicator accessories and holders made in Switzerland for Bestest, Interapid, Compac, Tesatast and all other high quality test indicators

We are pleased to offer you the following selection of top-quality Swiss-made test indicator holders and attachments. If you've been burned by cheap holders that won't fit, you'll appreciate these holders made by Tesa in Switzerland.

Although specifically designed for Bestest, Interapid, Compac and Tesatast indicators, these holders and attachments will work with any manufacturer's indicator that has a dovetail.

  • If you'd also like to see a high-quality Swiss-made indicator stand go to page 126.

Brown & Sharpe Universal Dovetail Attachment

Brown & Sharpe 599-7054 universal dovetail attachment fits any test indicator with dovetails such as BesTest, Interapid, Compac and Mitutoyo. The 1/4" diameter shank swivels until the knurled nut is tightened. Length of shank is 2-1/2" from the end to the center of the ball.


Swiss stem attachment – fixed or swivel style

Swiss quality and design made by TESA: attaches to the dovetail portions of all your test indicators. The stem portion can then be attached to any number of fixtures and holders. The swivel holder, with a 15mm long stem, shown above, rotates freely (±30°) in all directions until tightened into the desired position. It can be used on any brand of indicator that has dovetails (Mitutoyo, Starrett, Bestest, Interapid, etc.) including generic low cost indicators. Compac products were discontinued in 2020. Some of these stem attachments may no longer be available.

  • These are the best quality stems available.
  • Fixed stems are similar but do not swivel.

Test indicator angle holder

Rectangular or cylindrical shank

This indispensable universal holder for lathes and height gages has been newly redesigned by the manufacturer. They replace the former Compac model SP and SPA holder. The rectangular or cylindrical shank attaches firmly to any dovetail (any manufacturer) and then clamps into the tool post holder or into the height gage. The indicator can swivel into many positions and then stays securely fixed when the knob is tightened. It will also accommodate a dial indicator with a standard 3/8" diameter stem. It's also an ideal way to calibrate both your test and dial test indicators when used with a height gage and some gage blocks. Order one shank (rectangular or cylindrical) and one clamp shown below. Swiss-made by TESA.

  • Works in conjunction with a clamp. Order the items separately from the list below. The clamp attaches to any dovetail. The rectangular or cylindrical shank fits into the 5.6mm diameter hole on the clamp (shown below). Tightening the knob will tighten both the rectangular shank and the dovetail at once.

Interapid Indicator Swivel Holder

This versatile Swiss-made mounting stem (axial support) shown in the diagram above is 5-1/4" long and swivels at two points. The two joints allow for multiple positioning. One end has the dovetail attachment and an opening for the Interapid 4mm stem. An allen wrench (not supplied) is used to tighten the clamp. The other end has a mounting rod which can be gotten in two different diameters as follows:

  • 3/8" Ø rod (74.106931) 074106931 ... $118.00 order now
  • 8 mm Ø rod (74.106026) 074106026 ... $121.00 order now

A note of interest: there is a limited swivel of about 20% between the two leftmost joints on this holder. If you're at all handy with a Dremel and an abrasive sanding drum, you can modify the corners of these joints to give you complete side-to-side swivel.

Stem Adapter for 8 mm stems

This metal sleeve will fit over your 8 mm diameter indicator stem so that you can hold it with a 3/8" clamp or holder. Some of the best quality dial indicators only come with metric dimensions, so this adapter will be an absolute necessity if you're working in an imperial environment. Swiss made.
