Hey contractors and floor grinding pros! These premium diamond metal bonds are serious workhorses for your Newgrind Rhino floor grinder. You get three pieces in this pack, all G30 hard bond grit which is perfect for aggressive grinding and leveling on tough surfaces. They work with several Rhino models including the R5150, RXLP1500, RLP800, RM150, RS150, and RM350. The diamond size is 24x10x10mm, giving you a larger working surface than standard metal bonds, which means you cover more area faster. These things are built to last too - they average about 10,000 square feet of life, which is pretty impressive for hard bond tools. They work great on concrete, hardwood, terrazzo, and stone surfaces, making them super versatile for different jobs. Whether you're leveling uneven floors, removing coatings, or profiling surfaces for new coverings, these metal bonds deliver consistent, aggressive performance. The quality feels premium - you can tell these aren't cheap imports that'll wear out quickly. They maintain their cutting ability throughout their lifespan, so you get consistent results from start to finish. If you're tired of constantly replacing inferior grinding tools or need reliable performance for professional floor preparation work, these diamond metal bonds are definitely worth the investment. They'll save you time and money in the long run by lasting longer and working more efficiently than cheaper alternatives.
