VSM publishes CK721X as a silicon carbide grain on a sturdy X-weight cloth, full-resin bonded and closed coated, waterproof and oil-resistant.\u003c\/p\u003e\n    \u003cp\u003eCompared with the paper-backed VSM CP501 disc in the same size and grit, the cloth backing tears less on edges and tolerates wet use. It is still a coated abrasive: it sands and refines a surface but will not grind hard stone flat or take out a saw cut. For that use a diamond tool such as the SIERRA Resin-Filled Diamond Cup Wheel, 4 in.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"key-features\"\u003e\n    \u003ch3\u003eKey Features\u003c\/h3\u003e\n    \u003cul\u003e\n      \u003cli\u003e7 in. diameter, 7\/8 in. arbor hole, 80 grit.\u003c\/li\u003e\n      \u003cli\u003eSilicon carbide grain, closed coated, full-resin bonded.\u003c\/li\u003e\n      \u003cli\u003eX-weight cloth backing: VSM specifies X-polyester for grits P24 to P180, so this 80 grit disc is on the polyester cloth.\u003c\/li\u003e\n      \u003cli\u003eWaterproof and oil-resistant, so it can be run wet.\u003c\/li\u003e\n      \u003cli\u003e50 discs per box.\u003c\/li\u003e\n      \u003cli\u003eVSM developed CK721X for superalloys, unalloyed steel, composites, and glass, stone and ceramic; also suitable for aluminum, stainless steel, wood and rubber.\u003c\/li\u003e\n    \u003c\/ul\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"ideal-for\"\u003e\n    \u003ch3\u003eWho Is This For?\u003c\/h3\u003e\n    \u003cp\u003eFabricators and shop hands running 7 in. arbor-hole discs on stone, glass, ceramic and composite who want a cloth disc that holds up wet and on edges where a paper disc tears.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"faq\"\u003e\n    \u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n    \u003cdiv class=\"faq-item\"\u003e\n      \u003ch4\u003eIs this the same as the VSM CP501 disc?\u003c\/h4\u003e\n      \u003cp\u003eNo. CP501 is VSM's silicon carbide on paper backing.
