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.

Everything you need to polish flat surfaces with a reciprocating polisher. These kits include polishing bobs in different sizes and hardness ratings, along with buffing compounds. The bobs have a flat profile that moves back and forth with the motion of the reciprocating polisher. They’re good for large surfaces or squeezing into narrow, linear spaces. Use the beveled tip to polish at an angle.

Most buffing processes have two steps, cutting and coloring.

1. Cutting removes scratches and surface imperfections.

2. Coloring produces an even finish.
