Keep a variety of rectangular sizes and grits on hand to polish flat surfaces with a reciprocating polisher—no messy compounds required. These bobs are embedded with silicon carbide abrasive, which stays cool to prevent buildup. That makes them best for soft metals prone to clogging, such as aluminum. The abrasive also lets you cut fast without pressing hard. Their flat profile suits both large surfaces and straight, narrow spaces. The bobs have a beveled tip to polish on an angle. Grit is approximate. Labels in the lid include our part numbers, so it's easy to replenish the assortments.

Keep multiple shapes, sizes, and grits on hand to polish soft materials without any messy compounds. These bobs are embedded with silicon carbide abrasive, which generates minimal heat to reduce material buildup. That makes them best for polishing soft materials prone to clogging, such as aluminum. All cut fast and with light pressure. Use them to polish small areas and hard-to-reach spots with a drill or grinder for bits and burs. Grit is approximate. Labels in the lid include our part numbers, so it's easy to replenish the assortments.
