3M™ Scotch-Brite™ CF-MB Flap Brush

The 3M Scotch-Brite CF-MB brush is a 100 x 100 mm non-woven flap brush for machines. Soft but effective, it gives a uniform finish close to brushed stainless steel, without chatter marks.

Specifications

• Material: Scotch-Brite non-woven, CF web.
• Grades: A fine (aluminium oxide), S medium (silicon carbide).
• Dimensions: 100 x 100 mm, 19 mm bore.

Open, flexible flaps

The non-woven flaps are arranged radially and are very flexible. They conform to complex shapes without damaging the surface, and the brush gives a constant cut and appearance throughout its life. 3M stresses the absence of chatter marks, the ripples that appear when a tool that is too rigid bounces on the part.

A fine or S medium

The S medium grade, with silicon carbide, cuts more firmly: it is used to clean, remove oxidation and create a pronounced brushed finish. The A fine grade, with aluminium oxide, gives a softer, more even satin for finishing.

Applications

Satin finishing stainless steel sheets and parts, blending appearance after welding or touch-up, cleaning metal surfaces, finishing sections. The 100 mm width covers a large area with each pass.

Use

The brush fits a satin finisher or a machine matching its bore. Work with light pressure and regular passes in one direction for an even brushed finish. Respect the maximum speed shown.
