1. Strong applicability: all valves with angles of 18-62mm can be used; steel plate is optional

2. Forming at one time: processing the working face and chamfering at one time;

3. No need to be polished: The processed valve seat usually does not need to be polished and can be used directly with the new valve;

4. Precise positioning: It can accurately ensure the angle of the working surface of the valve seat, the position of the upper and lower chamfers, the width and the coaxiality with the valve guide;

Five uses: the reamer can be sharpened and replaced after the blade is blunt, and the entire reamer can be used forever. An investment will benefit for life.

6. Ability to process additional hard seat rings: the blade is made of cemented carbide and can process additional hard seat rings;

7. Special function: can hinge the valve seat and process the valve seat hole;

8. Improve work efficiency: Compared with old-fashioned reamer, work efficiency can be increased by more than 10 times. This kind of performance is beyond the imagination of ordinary people, and all old-fashioned reamers can be eliminated by purchasing a set.
