120/220 Grit Blend – Stage 2 Tumbling & Lapping Abrasive


The 120/220 Grit Blend is the ideal abrasive for Stage 2 of the tumbling process, designed to refine and smooth stones after the initial shaping stage. This blend contains both medium and fine particles, creating a balanced cutting action that’s fast yet gentle. The coarser particles continue refining the stone’s shape, while the finer particles—released as the grit breaks down—begin the smoothing process that prepares your material for pre-polish. This blend’s forgiving nature makes it perfect for both beginners and experienced tumblers, delivering dependable results in less time. Proudly manufactured in the USA for consistent quality you can trust.

Key Features & Benefits

  • Balanced particle size blend – Medium (120) grit continues refining shape, while finer (220) grit smooths surfaces for the next stage.

  • Forgiving action – Reduces the risk of over-grinding or pitting, making it easier to get consistent results across different stone types.

  • Time-saving progression – Coarse particles naturally break down into finer ones, so you get two stages of work in a single step.

  • Perfect for Stage 2 tumbling or lapping – Bridges the gap between aggressive grinding and fine pre-polish work.

  • Made in the USA – Ensures reliability, consistency, and high-quality performance.

Why Choose 120/220 Grit Blend

Stage 2 is all about moving from rough shaping to smooth refinement, and the 120/220 Grit Blend makes that transition seamless. Its unique particle range helps you work efficiently while setting the foundation for a flawless polish in the final stages.

I had a great experience working with Craig. I needed to change my order and they were already aware of my mistake with the saw size. Everything was so easy and smooth.

CabKing Grinder with attached saw

I have set up the grinding machine which was very easy. I have not used it yet but will be soon. I have taken it apart to set up the saw attachment which was also easy and have used that and am loving it.
