Supports valve guide hole diameter φ4.5! Even beginners can easily and accurately measure it.

This product is a valve seat surface runout measuring tool that can reduce variation caused by the measurer. By adopting our unique reference bar method, it is possible to easily measure the surface runout (concentricity) of the seat surface based on the valve guide hole within the engine and cylinder head. The reference bar section expands in relation to the finished diameter of the guide hole (with a tolerance range of φ0.05) and can measure without being affected by the hole diameter in a zero-gap state. 【Features】 ■ Reduces variation caused by the measurer ■ Easy maintenance ■ A three-row series that further improves rigidity and stability is also available ■ Adopts our unique high-precision reference bar mechanism at the valve guide alignment section ■ High versatility *For more details, please refer to the PDF document or feel free to contact us.
