Air Valve Lapping Tool (16mm, 20mm, 30mm, 35mm, 45mm) for Engine Head Overhaul and Valve Lapping.

This air-powered valve lapper eliminates the tedious manual process of rubbing valves by using compressed air to move them up and down and rotate, allowing for efficient work in a short amount of time.

It comes with five different lapper surface diameters, making it suitable for a wide range of valve sizes, from small DOHC valves to larger ones.

Using the appropriate valve compound for your application will ensure a clean finish.

It also comes with sealing tape to prevent air leaks, which is a nice bonus!

[How to Use] Attach the appropriate attachment for your valve size to the tip of the main unit, and adjust the airflow by turning the regulator while working.
