Covington Stage 1 Tumbling Grit 60/90
60/90 Grit Blend – Stage 1 Tumbling & Lapping Abrasive
60/90 Grit Blend is the go-to abrasive for the first stage of rock tumbling and lapping, designed to shape and smooth rough material efficiently. This blended grit contains a range of particle sizes, creating a unique cutting action that’s both fast and forgiving. The coarser particles tackle the heavy grinding, while the finer particles—produced as the grit breaks down—begin smoothing the surface. This natural progression not only saves time but also creates a smoother transition to the next tumbling stage. Proudly manufactured in the USA, this grit delivers dependable, professional results for lapidary enthusiasts at every skill level.
