Starrett® Surface Plate, No Ledge, 12 x 18 in Surface, 4 in Thickness, 0.00005 in Flatness Unilateral Tolerance, AA Laboratory Grade, Granite, Smooth, Crystal Pink®

• The name is derived from the fact that it has the highest crystalline quartz content of any granite surface plate
• 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
• Smooth, jewel-like quartz bearing points protect accuracy and finish of both the surface and the tools used on it
• 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
