Bristle Brush 3M™ CB-ZS

The 3M Scotch-Brite CB-ZS is a mounted combination wheel: it alternates flaps of aluminium oxide abrasive cloth with flaps of Scotch-Brite non-woven. It cuts and finishes in a single pass, and removes the scratches it creates.

Specifications

• Construction: alternating flaps, abrasive cloth and Scotch-Brite non-woven.
• Mineral: aluminium oxide.
• Attachment: mounted on a shank, for die grinders.
• Diameters: 75 and 100 mm.
• Grits: P60, P80, P120 and P180.

The combination wheel principle

A cloth flap wheel cuts fast but leaves a sharp scratch. A non-woven alone finishes well but removes little material. The combination wheel brings the two together: the cloth cuts, the non-woven that follows it softens the scratch. 3M sums up its benefit as cutting, removing scratches and producing a uniform finish, with good resistance to loading.

Applications

Deburring and finishing machined parts, blending light welds, cleaning oxidation, surface preparation before painting, satin finishing. Its mounted shape gives access to internal areas, radii and surfaces difficult to reach with a disc.

Choosing the grit

P60 and P80 for deburring and stock removal, P120 for an intermediate finish, P180 for a fine satin finish.

Use

Fit the shank fully into the collet of the die grinder, respect the maximum speed shown and work with moderate pressure: it is the speed and contact of the flaps that do the work, not pressure.
