Aggressive brush. Excellent for heavy-duty brushing such as deburring, cleaning, derusting and descaling and removal of spatter.

The Bosch X-LOCK system for angle grinders enables you to change tools quickly and easily. Instead of a round centre hole, the X-LOCK system features an X-shaped contour, which allows the tool to be fixed on the angle grinder in a form-fitting manner. This means different kinds of tools can be clamped in a reliable manner in a very short space of time. The unique system meets the highest of quality and safety standards and can withstand rough and harsh application conditions.|X-LOCK from Bosch is the world's first quick-changing system for angle grinders: Position the tool in the X-LOCK holder, click it into place – and you're ready! It's never been so easy to change accessories on angle grinders. X-LOCK is creating a new standard which makes professionals’ lives easier and increases their productivity. Bosch Power Tools relies on strong partners like PFERD. PFERD has developed the principle for connecting the X-LOCK punched part with the bonded abrasive, flap discs and brushes and created the conditions to enable them to be produced industrially.

In order to fulfil the particular requirements for working with stainless steel (INOX), PFERD uses wire quality 1.4310 (V2A) for all INOX brushes. Practical experience from industry has shown that this offers very good corrosion resistance with an optimum tool life. All PFERD brushes with INOX filaments are colour-coded in blue and are suitable for use on all stainless steels (INOX), such as V4A. The wire quality 1.4310 tends to become ferromagnetic in the case of cold working; i.e. it can be attracted using magnets.

Stainless steel wire (INOX) withstands temperatures up to 450 °C.

  • Aggressive brushing effect due to the very stiff wire knots.
  • With X-LOCK arbor for quick and easy tool changing.
  • Secure fixing as the tool audibly clicks into place.
  • Very good corrosion resistance.
  • The brush is degreased and does not leave any oil residue on the workpiece.
Recommendations for use
  • Please observe the recommended rotational speeds.
  • Place the tool on the X-LOCK quick-change system of your angle grinder and secure it by lightly pressing it down. The tool will audibly click into place.
  • Loosen the tool by actuating the lever.
