Lortone Graded Silicon Carbide Tumbling Grit

Take control of every stage of your tumbling process with premium Lortone graded silicon carbide grit, engineered for consistency, performance, and dependable results. Milled to precise particle sizes and tightly screened for uniformity, this graded grit delivers a predictable cutting action—ideal for lapidaries who want repeatable, professional-quality finishes. 80 Grit (Coarse Shaping) Start strong with 80 grit, a coarse abrasive designed for aggressive material removal and fast shaping. Perfect for smoothing rough edges and beginning the transformation from raw stone to refined form, this grit provides a uniform cut that helps eliminate major imperfections while preparing your stones for the next stage. 120 Grit (Refining & Smoothing) Step up to 120 grit to refine your work and improve surface quality. This medium-grade abrasive smooths out scratches left from the coarse stage and begins developing a more even, pre-polished surface—setting the foundation for higher grit finishing steps. Similar Lortone medium/fine grits are specifically used to improve surface finish and remove scratches from earlier stages. Crafted from extremely hard, sharp silicon carbide, these abrasives cut efficiently and continually fracture to expose fresh cutting edges—making them one of the most effective and reliable choices for rock tumbling. Whether you’re running a rotary tumbler or working on precision lapidary projects, Lortone graded grit gives you the control and consistency needed to produce beautifully shaped, smoothly finished stones every time.
