Features
 
Indicating Plug Gages 844D
 
- For the rapid testing of diameter, roundness and conicity of bores
- Especially suitable for testing batches with tight tolerance
- No rocking in the bore is required to determine the reversal point
- Measuring head has a hardened chromium plated guide cylinder and carbide tipped anvils
- Constant measuring force as a result of built-in spring, thus eliminating user influence
- Nominal diameter of the bore above 2.980 mm.

- For workpiece tolerance

- Use with 355E Ring Gage for highest accuracy

- Compatible with Diatest products
