Provides fast scratch removal on automotive white metal and other applications

Get a More Perfect Body in White
3M™ Trizact™ Hookit™ Cloth Disc 337DC was designed for automotive white metal repair. It is ideal for blending and finishing minor defects and for use to remove scratch marks left behind by metal files or rotary tools. It provides a very fast scratch removal capability combined with a superior finish, leaving the surface ready for e-coat application.

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

"Bricks and Channels" Abrasive Structure
Microreplication is the technology behind the geometrical "bricks-and-channels" abrasive structure of 337DC products. 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.

Get a Grip With Hookit Attachment
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.

Macroreplicated structure provides long product life and consistent cut and finish
