For accurate centring of a work piece or fixture on the mill.
The indicator body remains stationary while the spindle rotates a feeler around a bore, an external boss (up to 300mm diameter), or in a centre punch mark.
Rotate the spindle slowly under power and move the X and Y axes until the indicator needle stops moving. The set comprises:
- Coaxial Indicator
- 3 Straight (Internal) Feelers
- 3 Curved (External) Feelers
- Spring Loaded Centre Feeler
- Anti Rotation Rod
- Spanner, Storage Case and Instructions
- Shank Size: 10mm
Note: A coaxial indicator is used solely for centring.
The dial divisions should be treated as a scale of no dimension. They are not real metric or imperial measurements. Whilst the markings might give a true reading at a particular diameter; the indicator should never be used to take measurements.
