Forget the mess—polish soft metals and nonmetals without 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 and plastic. 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.

Eliminate the need for messy compounds while polishing hard metals. These bobs come embedded with diamond, the hardest abrasive we offer. They’re best for cutting into stainless steel, titanium, and other tough materials. Use them to polish small areas and hard-to-reach spots with a drill or grinder for bits and burs. Grit is approximate.

Skip the messy compounds—these bobs come embedded with aluminum oxide, the most common abrasive material. Best for polishing steel, they’re also a good all-purpose option for other materials when specialty bobs aren’t available. Use them to polish small areas and hard-to-reach spots with a drill or grinder for bits and burs. Grit is approximate.

Keep multiple shapes, sizes, and grits on hand to polish hard metals without any messy compounds. These bobs come embedded with long-lasting diamond abrasive—the hardest we offer. They’re best for cutting into stainless steel, titanium, and other tough materials. 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.

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.

Pop these rectangular bobs onto a reciprocating polisher to glide along flat surfaces—no messy compounds required. They're 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.

Polish delicate surfaces that are easily scratched, such as glass and ceramics, without messy compounds. These bobs are embedded with cerium oxide abrasive, which is less aggressive than other materials. They remove light scratches, scuffs, cloudy surfaces, and hard water etching. Polish small areas and hard-to-reach spots using a drill or grinder for bits and burs.
