Why This Brush Kit Is the Perfect Buy
Buying three shapes in one box saves time and money: swap heads in seconds instead of reaching for multiple single-purpose tools. The 3mm shank is the most common size in EU-market rotary tools, so you can move from delicate engraving work to heavy rust removal without changing collets. With twelve brushes on hand, you always have a fresh head ready when bristles wear down.

Interesting Facts About Wire Brushes
- Wire brushes date back to the 19th century and were first used in shipyards to prepare steel hulls for painting.
- Steel bristles are ideal for ferrous metals, while copper or brass bristles reduce scratch risk on aluminium and softer alloys.
- A finer wire diameter produces a smoother finish but removes material more slowly; these brushes balance moderate aggression with good surface quality.
- Keeping a light touch and letting the bristles do the work extends brush life and reduces heat buildup.
- Wire brushing before welding removes oxides, resulting in cleaner welds and stronger joints.

Equip your rotary tool with this 12-piece 3mm steel wire brush set and tackle rust, paint, burrs and grime with professional efficiency.
