Need a tough cutting wheel for stone, tile, or concrete? This CDE-4 diamond wheel from LOBSTER (yep, the Japanese brand with the shrimp logo!) is built to last. Specs: 98mm outside diameter, 4.5mm thick, with a 7mm wide diamond cutting layer and a 15mm arbor hole. It's designed for high-speed work—handles up to 14,500 RPM—so it's great for angle grinders. The diamond grit is rough to medium, giving a good balance of cutting speed and finish. LOBSTER tools are known for being heavy-duty and long-lasting (hence the lucky lobster symbol!), so this isn't some flimsy disc. Perfect for pros or serious DIYers tackling masonry, tile jobs, or stone shaping. Imported from Japan, quality you can trust. Use it dry or wet, but always follow safety guidelines—goggles and gloves, folks! Makes clean cuts, reduces chipping, and lasts way longer than cheap abrasive wheels. Check your tool's specs before buying to ensure compatibility. A reliable addition to your workshop for those tough materials.
