3 legged glaze breaker. Almost new - used once on small motorcycle so as new. Suitable for the cleaning of cylinder bores of up to 180mm. Adjustable collar gives 2 ranges 50-100mm and 100- 180 mm. Flexible drive operates from a power drill. This is a quality tool , not cheap copy. It works as it should with unworn stones. Don’t risk your project with cheap tat.
