Brown & Sharpe / TESA
Style A Intrimik / Imicro Hole Micrometer for deep hole measurement to 40 inches

 

599-281-10 (.8-1.0" range) shown above. Wrenches and adjusting screw driver are included, but the setting ring is optional.

Made in Switzerland by TESA for Brown & Sharpe. Direct analog readings of bore diameters, using 3-point measurement. This eliminates errors associated with comparator gages such as dial bore gages. Readings are taken directly from the vernier on the thimble, just like a micrometer.

These B&S Intrimik models are available to read diameters from .275" to 12". With optional extensions, the depth of the bore can be as much as 40 inches. Metric versions read from 3.5 mm to 300 mm with a 100 cm depth extension available on larger models.

If you look at the location of the measuring arms in the photo above, you'll notice that it will not be possible to measure to the very bottom of blind holes with this particular model (use the Etalon ingage instead on page 166). For calibration purposes, one setting ring (not included) will be required per tool (see page 163).

Individual gages come in shipping boxes, complete sets in plastic cases. Serial numbers on the gage are suitable for ISO compliance. Factory inspection report is included.

These are of the very best workmanship. Asian made holemikes, available for a fraction of the cost, are no comparison. These Swiss tools can last a lifetime.

(*) Stock is limited at this special discounted price.

Metric models are also available. Please inquire.

Accuracy is listed as total accuracy, not plus/minus, according to the manufacturer (May 2012).

  • Up to 2 inches = .00016"
  • Up to 4 inches = .00020"
  • Up to 12 inches = .00024"

Setting rings are an absolute necessity when working with these hole micrometers. They are shown on page 163.

Using an Extension

 

Depth extensions in the following sizes are available: 4-inch, 6-inch, 20-inch and 40-inch. Extensions can be combined but it's better to use a single 20 inch extension than three 6-inch extensions, for example. Extensions are not necessarily interchangeable between models because the body diameters differ. If you need an extension for your Intrimik, please contact us to see what's available for your particular model.

  • With two wrenches, unscrew the measuring head as shown in Fig 4 (below).
  • Unscrew the threaded cone as shown in Fig 5.
  • Replace the threaded cone with the extension rod.
  • Screw the extension sleeve into position.
  • Replace the threaded cone, screwing it into its new position and tighten.
  • Screw measuring head in position. Caution: Care should be taken that all parts are secure but not over tightened. Keep parts thoroughly clean.
  • Rest the Intrimik to zero before use.

Q: What have you guys found to be the main contributor to Brown & Sharpe/Tesa Intrimik non-linearity? Could it be the customer is repetitiously using the micrometers to measure one specific diameter, causing uneven wear to the cone “threads” or brass frame threads?

A: To make it as simple as possible: human error and misuse of a gage would be number one; dirt, grime, rust, would be number two; the repeated use of a gage in a given range would be number three. It could also be human error or damage due to a fall. Face it, every person at some time or another has tightened a gage just a little too much on a part in order that it meets specs. Unfortunately not every gage can tolerate that—especially the gage in question. Once those internal steps are worn the entire cone, and the arms, need replacing and that becomes an uneconomical repair.
