ARTCO mounted Felt Bobs are manufactured from 100% wool and provide an exceptional material for polishing all types of metals. Available in a range of densities - soft, medium, hard, and rock hard. Felt bobs are designed to be charged with various rouges, lapping, or diamond compounds to produce the high finishes required in the precision deburring and mold polishing industries. The harder the density, the more resilient and aggressive the wheel. Softer densities will produce finer luster finishes and conform more readily to part contours. Medium density is most commonly preferred. Each felt shape MS4, MS5, and MS6 (shown from left to right in adjoining photo) is available in three different sizes. See chart below. Note shank sizes.
Please note that Rock Hard and Soft may not be available for all shapes. MS62AS will be discontinued when present stock is depleted.
