If you have any questions, please send us a drawing or sketch with details of the larger opening, measuring depth and recess diameter with tolerance and recess width (B)
Execution
- Supplied without basic unit/holder, please refer to article number 33576010

Advantage
- Rapid measurement of groove/recess diameters in bores
- High measuring pressure ensures reliable measurement
- Especially suitable for series measurement
Notes
IMPORTANT: The measuring instrument will not work without the basic unit (33576010) and the measuring contact (ONM only). A dial gauge/precision pointer and an adjustment tool are also required.
