For my application it worked because this was a consumable wheel for truing and dressing a resin bond diamond wheel for a cylindrical grinder. This silicon carbide grinding wheel was mounted on the workhead spindle and rotated at 200RPM and successfully was able to dislodge grains from the diamond wheel. But a lot of this silicon carbide wheel needed to be ground away before the runout was eliminated.

For my application it worked because this was a consumable wheel for truing and dressing a resin bond diamond wheel for a cylindrical grinder. This silicon carbide grinding wheel was mounted on the workhead spindle and rotated at 200RPM and successfully was able to dislodge grains from the diamond wheel. But a lot of this silicon carbide wheel needed to be ground away before the runout was eliminated. ### ⭐⭐⭐⭐ When removing a lot of metal, such as glaze, rust, slag etc *by V***E on February 10, 2024* Trying a lighter ceramic disc, this was good but a bit heavy for prolonged use ### ⭐ Too heavy *by J***E on October 24, 2022* I had planned to use it on a quartz tabletop sink cutout. The weight of it was too heavy for the variable grinder which caused it to oscillate. I did not touch the quartz and was able to return it. I needed “manageable and smooth” for which this was the wrong drum. ## Frequently Bought Together - SIGNI 4 Inch Green Grinding Stone with 5/8-11 Thread (1 Pack,80 Grit，4X2X5/8-11) - 4 Inch Diamond Polishing Pads with 5/8’’-11 Backer Pad, 12PCS Wet/Dry Granite Stone Polish Pad Kit for Drill, Grinder, Polisher, 50-6000 Grit Polishing Pad for Concrete Marble Rock Countertop Quartz - SIGNI 4 inch Silicon Carbide Grinding Stone with 5/8 Arbor for Grinding Masonry (24 Grit) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/166346211-signi-4-inch-green-grinding-stone-4x2x5-8-11-threaded](https://www.desertcart.vu/products/166346211-signi-4-inch-green-grinding-stone-4x2x5-8-11-threaded) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-06-04*
