Question 1

What surfaces and materials is it suitable for?

Accepted Answer

It is ideal for metal surfaces such as aluminum, steel, and copper. It can prep surfaces for painting, deburr edges, clean welds, and erase heavy oxidation. Avoid using on soft plastics or highly polished mirror finishes, and test on a small area first to prevent surface damage.

Question 2

Is this brush compatible with power tools I already own (RPM and fit)?

Accepted Answer

The cup brush is designed to fit standard power-tool arbors and is suitable for typical workshop speeds. Always verify that your tool’s RPM rating falls within the brush’s recommended operating range and that the arbor diameter matches the brush attachment. If in doubt, consult your tool’s manual or contact Fepy support for compatibility guidance.

Question 3

What is the expected lifespan and how can I maximize it?

Accepted Answer

Lifespan depends on usage, material, and workpiece condition. Regularly inspect for missing or bent bristles and replace when performance declines. To maximize life, use appropriate tooling speed, avoid excessive pressure, and rotate through multiple brushes during heavy tasks to prevent wearing one brush unevenly.

Question 4

Can this brush be used for painting prep and welding cleanups?

Accepted Answer

Yes. It’s effective for removing old paint, rust, and scale from metal surfaces and for cleaning weld seams. It helps create a roughened, clean surface that improves adhesion for primers and paints, and it can be used to deburr and clean weld joints.

Question 5

What safety and maintenance steps should I follow?

Accepted Answer

Always wear eye protection and gloves. Keep a firm grip and avoid excessive pressure to prevent bristle breakage. Inspect bristles before use and replace if bent or damaged. Use in a well-ventilated area to avoid dust and debris buildup, and unplug tools before changing attachments. Do not use near live electrical components and avoid contacting operators or bystanders with the rotating brush.

Question 6

How do I choose the right size and bristle type for my task?

Accepted Answer

Choose based on access and the area to clean: larger cups cover more area and remove material faster, while smaller cups fit into tight spaces and offer more control. Bristle density and wire thickness affect aggressiveness — denser and thicker wires remove material more quickly but can be harsher on delicate finishes. For delicate or intricate parts, start with a lighter brush and test on a hidden area.
