Forum Round brush steel wire 125 mm knotted

Trimming material of wire brushes

Steel wire, smooth and knotted
- For less flexible brushing
- For welding, derusting and cleaning work
- For steel and cast iron (smooth also for wood)

Steel wire, crimped
- For flexible brushing
- For
light surface treatment and deburring
- For steel, cast iron and wood

Rust-free steel wire, smooth, knotted and crimped
Like steel wire, but for
- Stainless steel, aluminum, non-ferrous metals

brass wire, crimped
- For flexible brushing
- For light cleaning and surface finishing
- For
non-ferrous metals (especially copper and copper alloys) and soft wood

Nylon, smooth
- For flexible brushes
- Resistant to weak acids and alkalis
- Abrasion resistant

Cutting speeds and application notes

Determining recommended speed
- Select brush Ø
- Select cutting
speed according to brush and application
- Read speed

Guide values
- Brushes with crimped steel wire approx. 30-35 m/s
- Brushes with knotted steel wire on angle grinders 85 m/s, on stationary machines up to max. 45 m/s
- Select largest possible brush Ø for application and drive unit
- Ideal speed is usually
well below maximum speed

Safety instructions
- Wear suitable protective clothing (e.g. eye, ear and respiratory protection)
- On hand-held machines, only equip brushes up to max. Ø 180 mm
