Non-Woven Disc SE-DR 3M™ Scotch-Brite™ Roloc™

The Scotch-Brite Roloc SE-DR disc combines a coarse non-woven with the 3M Roloc quick-change attachment system. It deburrs, cleans and conditions a surface without dulling or scratching the substrate.

Specifications

• Grain: aluminium oxide, in coarse, medium and fine grades.
• Diameters: 50 and 75 mm.
• Attachment: Roloc TR, screw-on.
• Materials: mild steel, stainless steel, aluminium.

The Roloc system

The disc screws onto its holder with a quarter turn and comes off just as quickly. At a workstation where grades are switched several times per part, this is what makes the difference in throughput compared with a centre hole and nut.

The screw-on attachment also holds better than hook-and-loop on small diameters, where the loop surface becomes insufficient against the torque.

What a non-woven does that a coated abrasive does not

Its structure is an open web in which the grain is distributed. It resists loading and heat build-up and, above all, it does not clog: particles pass through it instead of building up between the grains.

As a direct result, it performs on aluminium and paints, which load a paper disc in seconds. And it works the surface without changing the part's dimensions, so a local defect can be reworked without leaving a visible flat.

Choosing the grade

Coarse removes light weld, mill scale or paint. Medium blends and prepares for painting. Fine satin-finishes and completes the job.

Work with moderate pressure: pressing harder does not cut more, it crushes the fibres and uses up the disc for nothing.
