Round Ball Contact
Cupped Style with carbide, ruby, nylon, or Teflon
The most common, and probably most useful contact point has a large 3 mm diameter carbide ball (.06" radius) inset into the cupped end of the point. Only a portion of the ball will be visible. The ball does not rotate and is not designed to rotate. This type of contact point should be used when flat surface measurements are taken.
Carbide will provide a long useful life for these points particularly if any sliding motion is involved. Sliding the test piece under the contact point will inevitably wear down the point. For special applications, this ball can be made of synthetic ruby, Teflon or Nylon. The length (L) of the point can be altered by using a separate length extension.
- Inset ball diameter is 3 mm
- Outside diameter is 5 mm
