Explore the contents and purpose of the Brass & Copper 3-Step Buffing Kit for Angle Grinders. Learn what each compound does and how to achieve a mirror finish on non-ferrous metals.
Quick Answer
The Brass & Copper 3-Step Buffing Kit includes three felt flap discs and three color-coded compounds (brown Tripoli, white rouge, and jeweler's rouge) designed to take brass and copper from scratched to mirror-finished using an angle grinder.
What makes this kit different from a general buffing kit?
This kit is formulated specifically for non-ferrous metals like brass and copper. The three compounds progress from cutting (removing scratches) to polishing (developing luster) to final coloring (mirror shine). General kits may skip the final jeweler's rouge step, which is essential for the deep reflective finish that brass and copper are known for.
Frequently Asked Questions
- What is the first step (brown Tripoli) for?
- The brown Tripoli compound is a cutting compound. It removes scratches, oxidation, and light surface imperfections from brass and copper. Use it with firm pressure on the felt flap disc.
- What does the second step (white rouge) do?
- The white rouge compound refines the surface to a natural luster. It removes the haze left by the Tripoli and begins developing a bright, even finish. Reduce pressure compared to step one.
- Why is jeweler's rouge the final step?
- Jeweler's rouge is a very fine polishing compound that produces a high-gloss, mirror-like finish. It is the final coloring step that gives brass and copper their characteristic deep reflective shine. Do not skip this step if you want a true mirror finish on decorative or display pieces.
- Can I use this kit on other metals?
- This kit is optimized for brass and copper. For stainless steel or white metals, use the Stainless Steel & White Metals 3-Step Buffing Kit, which uses black emery, gray stainless, and emerald green compounds. Using the wrong compound sequence on stainless steel can leave swirl marks or inadequate polish.
- Do I need anything else to use this kit?
- You need an angle grinder with a 4-1/2" or 5" backing pad (the felt flap discs mount directly). No additional compounds or wheels are required for the three-step process. Check that your grinder has a spindle lock for quick disc changes between steps.
Product Facts
- Brass & Copper 3-Step Buffing Kit For Angle Grinders: The kit contains three 4-1/2" felt flap discs, one brown Tripoli compound (first step), one white rouge stainless compound (second step), and one jeweler's rouge compound (third step). You get everything needed for the full three-stage process in one box, so you don't have to source compounds separately or guess which grit to use next.
