3M™ Scotch-Brite™ Bristle RD-ZB Resin Disc

The 3M Scotch-Brite Bristle disc RD-ZB is a disc of moulded thermoplastic bristles loaded with ceramic grain, with Roloc quick-change attachment. It strips, cleans and deburrs metals without the wires of a wire brush.

Specifications

• Mineral: ceramic grain in an injection-moulded thermoplastic resin.
• Attachment: Roloc type R.
• Diameters: 25, 50 and 75 mm.
• Grits and colours: P36 purple, P50 green, P80 yellow, P120 white.

An alternative to the wire brush

3M presents the Bristle as an alternative to wire brushes and chemical strippers. Its bristles are moulded in one piece: no wire to break off and lodge in the skin or the part, no metal contamination of the surface, and therefore less risk of corrosion on stainless steel or aluminium.

The three-dimensional structure is flexible: the bristles conform to complex shapes, corners and contours. They do not clog and need little pressure to clean or strip.

Applications

Removing paint and rust, cleaning welds and oxidised areas, removing gaskets and adhesive residue, light deburring, surface preparation before welding or painting. The colour code makes it easy to identify the grit at a glance at the workstation.

Use

Fit the disc on a Roloc disc holder on a die grinder. Work with the bristle tips and light pressure: it is the grain-loaded tip that does the work. Pressing hard flattens the bristles and reduces effectiveness.
