M1.4 BesTest Test Indicator Contact Points

M1.4 Tesatast Contact Points

Carbide, Ruby, Nylon and Teflon contact points for the Swiss made Bestest and Tesatast test indicators

The model suffix (-3 and -5) refers only to whether the dial is white or black. For example 7030-3 and 7030-5. Older, obsolete models had -2 or -1 as a suffix. They also use the same contact points. Points are identical for inch and metric models. Thread size is M1.4 (outside diameter is about 1.4 mm).

You can also buy a special double length point which is 1" long (28 mm from shoulder to center of ball). When installed, the readings on the dial will be doubled. In other words, the .0005" indicator will now read .001". Make sure you label your indicator when you do this, so that no one misreads the dial.

How are they measured? From the shoulder (not including the thread) to the center of the ball. Custom ball diameters are available as well as teflon and nylon. Bestest contact points can be used with the Adapt-A-Tip adapter for dial and digital indicators.

Why are there multiple ordering numbers? The points are the same but the Brown & Sharpe (B&S) numbers are used in the USA, while the TESA numbers are for the rest of the world, while MTC is a numbering system we use. You may also encounter variations on the TESA numbers, such as 018602-00, 18.60202 or 01860202. (Notice that this merely eliminates the decimal point and adds a leading zero.)

.080" carbide points are standard and are installed on all new BesTest indicators. Contact points are generally in stock. Larger orders may, however, require 2-3 weeks.

Carbide, Ruby, Nylon and Teflon points

These contact points are used for special applications, typically in optics.

  • The carbide point comes standard with your new BesTest or Tesatast indicator. It is the most durable for general measurement.

  • The ruby point outlasts standard chrome points and does not expand or contract with heat and cold. It does not conduct an electric current so it can be used on your machines without creating interference. It is also less likely to scratch delicate surfaces. It's also the material that will hold up to silicon carbide surfaces.

  • The Teflon point is softest made of a solid Teflon ball. It is very white in appearance. It is least likely to scratch but is not as long lasting as the others. The smallest Teflon diameter available is 1/16" (.062"). Smaller points can not be manufactured in this material.

  • The Nylon point is not as soft as Teflon but will last longer. It can also be used where surface damage is an issue. Nylon appears opaque.

Contact Point Wrench works with all BesTest points but needle-nosed pliers will work just as well.

Tesatast and SwissTast

Points are identical for inch and metric models. For that matter, these points are identical to Bestest points. You can order any of the Bestest points on this page but be sure to order the correct length as shown below.

Federal

The discontinued Federal Series 100 indicators (T-101, T-102, etc.) were manufactured by Tesa in Switzerland. The contact points are identical to those used by the Brown & Sharpe Bestest indicators.

Old style points (M-1, T-1, etc.) had ratchets rather than threads. They are no longer available from us.
