Steel Shot Abrasive also known as Ball Shot is a high performance is a spherical product of hypereutectoid steel in a heat treated tempered condition.
It has a uniform structure which provides optimum resilience and resistance to fatigue, and remains Round throughout its working life.
It used Impact rather than a cutting process, leaving minimal dust.
