Collection: 3M™

3M was born in 1902 in Two Harbors, Minnesota, as the Minnesota Mining and Manufacturing Company. Its five founders set out to mine corundum, the ideal mineral for making sandpaper. The deposit held no corundum but anorthosite, and the company nearly failed before it began. It rebuilt itself on abrasives, then on adhesives, and those two trades remain the core of what Dagobert Industrie distributes today.

Abrasives

This is the largest family. It covers sanding discs on paper, cloth, film and mesh, fibre discs for angle grinders, abrasive belts, rolls, sheets, sponges and cut-off wheels.

Three ranges structure the offer. Cubitron is built on precision-shaped ceramic grain, cut into triangles that renew themselves as they fracture: the abrasive cuts instead of rubbing, which limits heating of the workpiece. Scotch-Brite covers the non-woven abrasives, used for deburring, satin finishing and finishing, where a conventional abrasive would remove too much material. Trizact structures the grain into regular micro-reliefs, for a progressive, consistent finish until the disc is worn out.

Adhesives and tapes

The range runs from VHB acrylic foam double-sided tapes, which replace screws and rivets on certain assemblies, to single-sided tapes in cloth, vinyl, polyester and aluminium, by way of hot melt adhesives, spray adhesives and Scotch-Weld two-part epoxies.

Personal protection

Reusable and disposable masks, filters and cartridges, Peltor hearing protection, Speedglas welding helmets and Versaflo powered air systems.

Understanding the 3M abrasive families

Faced with two discs that look alike, three questions usually settle it.

1. What is the grain? Precision-shaped ceramic grain, as in Cubitron, removes more material and lasts longer than conventional aluminium oxide, but costs more. It is justified as soon as operator time weighs more than the price of the consumable.
2. What is the backing? Paper is economical and stiff, cloth resists tearing and moisture, film offers a very consistent thickness for fine finishing, mesh clears dust across its whole surface.
3. What is the attachment? Hookit hook and loop changes in seconds and can be reused, the Roloc screw-on holds better on small diameters when deburring, Stikit adhesive suits flat pads and long runs.
