Starrett 80883 Crystal Pink Granite Surface Plate, Grade AA Laboratory, No Ledge, 30" x 48" Surface Size, 10" Thickness

Even distribution of large quartz crystals provides a smooth finish, which significantly reduces wear on the surface plate and the instruments used on it. Fine micro-finish, combined with the natural voids in the surface, prevents wringing and provides a velvety-smooth tool action. Non-quartz-bearing granite in average daily use requires resurfacing about once a year, while crystal pink plates used in these same plants have required resurfacing only once every three to five years, on average. Great surface hardness and wear resistance the highest percentage of quartz crystals of any granite plate. Quality and economy combined. Comparable to black granite plates while outwearing them as much as 5 to 1. Standard-size plates are mounted on resilient support pads, providing isolation from normal vibration and a non-distorting 3-point suspension. Packed one per crate with skids for forklift handling.
