What it is
The Fervi SFR022I twisted-knot end brush is the stainless steel wire version of the Fervi end brush range, dedicated to cleaning and finishing surfaces. The twisted-knot configuration gives the tool a decisive action and good durability, while the use of stainless steel makes it particularly suitable when working on materials where ferrous contamination must be avoided. The product is certified Italian-made and complies with Machinery Directive 2006/42/EC with CE marking, mounted on rotary tools by its shank.
A rotary brush is a twisted-knot wire or nylon accessory for grinders, drills and bench machines that removes rust, paint and scale.
What it is for
Used for preparing joint edges before welding, for cleaning oxides, grease and machining residues from metal and for removing rust and oxides.
How to use it
Fit the brush to a machine with a compatible attachment, checking that the brush's maximum speed is higher than that of the machine. Run it unloaded for a few seconds away from other people, then work with light pressure: pressing too hard bends the wires and makes them break off. Use stainless steel wire brushes on stainless steel, and always wear safety glasses or a face shield and gloves.
