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.

Steel wire is the most common filament material. Brushes with steel wire as the filament material are especially well-suited to work on surfaces and deburring. PFERD special wire has high tensile strength and bending fatigue strength. This ensures that the wire wears down in the optimal way, as well as a long tool life, even in extreme brushing applications.

Steel wire withstands temperatures up to 300 °C.

  • Aggressive brushing effect due to the very stiff wire knots.
