3M™ Trizact™ Hookit™ Cloth Disc 337DC, 5 in x NH, 5 Hole, A300 X-weight, D/F, Die 500FH, 50 ea/Case

3M™ Trizact™ Hookit™ Cloth Disc 337DC is a product designed for automotive white metal repair. It is perfect for blending and finishing minor defects and removing scratch marks left behind by metal files or rotary tools. This product provides a fast scratch removal capability and a superior finish, leaving the surface ready for e-coat application.

This cloth disc is available in 5-inch diameters and grades of A300, A160, A100, A65, A45, A30, as well as make-to-order sizes.

The geometrical "bricks-and-channels" abrasive structure of 337DC products is made possible by microreplication technology. These unique abrasive bricks contain up to four times as much mineral as conventional abrasives. As the mineral breaks down, fresh mineral is exposed.

The microreplicated pattern of 3M™ Trizact™ Hookit™ Cloth Disc 337DC generates minimal heat. The open spaces between the abrasive bricks channels heat away and removes swarf. This means you can use these discs on substrates like galvanized panels, aluminum hoods, and other applications where loading may be an issue.

3M's Hookit™ hook-and-loop attachment makes disc attachment, removal, and re-attachment clean and easy, and facilitates re-use of the disc for the extent of the abrasive life.

It couldn't be simpler to attach a disc and it stays firmly seated. In addition, they are more flexible and they resist contamination by dust, dirt, and debris, unlike pressure sensitive adhesive backings.

3M's microreplication technology allows them to engineer the geometry of abrasive grain, to create and reproduce perfectly calibrated three-dimensional composite structures —pyramids, hemispheres, cubes — and distribute them precisely and uniformly across an abrasive backing. Each is identical in height and orientation, eliminating the danger of uneven edges or deep scratches. As the abrasive wears, a continuous supply of fresh, sharp abrasive mineral is exposed, sustaining consistent cutting performance and profile.

The science that makes 3M's structured abrasives work better and wear more evenly, provide pristine finishes for delicate components is also the science that makes road signs, electronic displays, and exterior building illumination capture and reflect light more brilliantly.
