Lortone Ungraded Grit

When you’re serious about transforming rough stone into beautifully shaped pieces, your results depend on one key decision most beginners overlook—the type of grit you use at every stage. Upgrade your entire tumbling process with Lortone Silicon Carbide Ungraded Grits, available in 46/70 (Stage 1), 60/90 (Stage 2), and 120/220 (Stage 3)—each designed with a mixed particle size that delivers faster, more efficient results than traditional graded abrasives. Unlike graded grit, where all particles are uniform in size, ungraded grit blends multiple particle sizes together. This creates a powerful cascading effect inside your tumbler: Larger particles break down rough material quickly Medium particles refine surfaces as the tumble continues Smaller particles fill in gaps and smooth inconsistencies The result? A continuous cutting and refining action in a single stage, reducing wasted time and helping you move through the tumbling process more efficiently. Stage-by-Stage Performance ⚡ 46/70 Grit (Stage 1 – Aggressive Shaping) Start strong with an extra-coarse blend that rapidly removes material, rounds edges, and breaks down even the toughest rough. The mixed sizes ensure that as larger particles fracture, smaller ones take over—keeping the cutting action consistent throughout the cycle. 🔄 60/90 Grit (Stage 2 – Controlled Shaping & Smoothing) This versatile mid-coarse grit continues shaping while beginning to smooth surfaces more evenly. The ungraded blend helps eliminate deep scratches left from Stage 1 faster than uniform grit, bridging the gap between heavy shaping and pre-polish refinement. ✨ 120/220 Grit (Stage 3 – Pre-Polish Preparation) Prepare your stones for polishing with a finer ungraded mix that smooths surfaces efficiently while still maintaining light cutting action. The varied particle sizes help remove remaining imperfections and create a more uniform surface ready for polish. Why Ungraded Grit Is the Better Choice 🚀 Faster results – multiple particle sizes work simultaneously 🪨 More efficient material removal – no “dead time” between grit breakdown 🔁 Smoother stage transitions – each stage naturally blends into the next ⏱️ Reduced tumbling time – get to polish-ready stones quicker 🎯 More consistent finishes – fewer deep scratches carried forward Using ungraded grit at every stage isn’t just a small upgrade—it’s a smarter system. From aggressive shaping with 46/70, to controlled refinement with 60/90, to smoothing with 120/220, each step works harder for you thanks to its mixed particle design. If you want to maximize efficiency, reduce cycle time, and achieve better results with less guesswork, Lortone’s ungraded silicon carbide grit lineup is the way to tumble.
