Gunson Eezilap Valve Lapper

Lapping in valves by hand is a laborious process – particularly if the head has more than two valves per cylinder.

This drill-mounted valve lapper grips and turns the valve stem producing a gas-tight seal 60 times faster than you can do by hand.

It fits all drill chucks 8mm (5/16″) or larger and comes with two interchangeable suction cups and instructions for use.
