Bosch PRO 0.35mm Knotted Steel Wire Cup Brush

The Bosch PRO 0.35mm Knotted Steel Wire Cup Brush is a heavy-duty grinder accessory designed for cleaning, descaling, and surface preparation on steel.

Built with premium knotted steel wire at 0.35mm thickness, this 75mm cup brush is well suited to tackling heavy rust, old paint, varnish, underseal, and welded seam cleaning. The knotted wire construction delivers consistent, long-lasting performance across demanding metalworking applications.

With a 0.35mm wire diameter, this brush produces a relatively smooth surface finish compared to thicker wire variants — making it a practical choice when a cleaner result is needed without sacrificing material removal speed.
