Its job is to take out the scratch pattern the coarser wheels leave, so the first polishing pad starts on an even surface. Resin fills the gaps between the diamond segments, so the wheel runs on a near-continuous face instead of open segments, which keeps it from bouncing, chattering and chipping. V2 adds a new, improved diamond segment pattern over the original SIERRA cup wheel.\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\u003e4 in. diameter, 5\/8 in.-11 thread\u003c\/li\u003e\n\u003cli\u003eFine grade, the finest of the three V2 grades, for refining rather than removing\u003c\/li\u003e\n\u003cli\u003eResin-filled face that resists bouncing, vibration and chipping\u003c\/li\u003e\n\u003cli\u003eHigh diamond concentration for long life and even stock removal\u003c\/li\u003e\n\u003cli\u003eNew V2 diamond segment pattern\u003c\/li\u003e\n\u003cli\u003eWet or dry use, rated to 10,000 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"not-for\"\u003e\n\u003ch3\u003eWhat This Is Not For\u003c\/h3\u003e\n\u003cp\u003eDekton, porcelain and other ultra-compact surfaces.
