Our 1" diameter white Radial Bristle Discs were developed by 3M especially for jewelers. Each flexible plastic disc is color-coded to denote grit. No compound is necessary, grit is uniformly dispersed throughout the disc. You work faster and clean-up is that much easier! Use for cleaning, pre-polishing, blending and removing scratches and firescale. Excellent for gold, silver, copper, pewter and brass. Discs can be used singly to access tiny or hard-to-reach areas. They can also be stacked to make a thicker brush for covering large surface areas.
Three diameters to choose from: 9/16", 3/4" and 1". Please note: 1" discs are available in limited colors/grits.
General rule of thumb, the more aggressive grits, Brown (36), Green (50), and Yellow (80) are excellent for removing scratches and firescale. Use the White (120) for texturing and light cleaning while the Red (220) can be used for removing light scratches and oxides. Consider the Blue (400) when you need to blend and are pre-polishing. The Pink (pumice) is also excellent for pre-polishing as well as very light cleaning. The finer grits Peach (6 micron) and Light Green (1 Micron) are used for polishing.
