Our 3M™ Roloc™ Flexible Diamond Disc 6234J delivers consistently superior results on hard-to-grind materials like stone, glass, ceramic, metal, carbide and composites. Metal-plated bond anchors micron-graded diamonds to a heavy-duty polyester backing for flat, edge, contour grinding and polishing. Improved Finishes, Improved Productivity The sharp, smooth cutting action of our 3M™ Roloc™ Flexible Diamond Disc 6234J consistently achieves improved finishes on a wide range of hard-to-grind materials – without sacrificing cut rates. The open-dot pattern of micron-graded diamond abrasive helps prevent loading and encourages coolant flow and swarf removal. In combination with a heavy-duty, water resistant, polyester backing, this is a durable, long-lasting disc suitable when you need the toughness of diamond. Quick-change Roloc™ Attachment 3M™ Roloc™ TR quick change discs are smaller discs that have a plastic threaded button or screw designed to easily and quickly screw onto a Roloc™ TR disc pad (sold separately) so that operators can conveniently change discs with a simple twist-off, twist-on motion. The Roloc™ TR system provides a secure attachment even for heavy-duty applications, and the variety of available 3M Roloc discs allows swapping from one application to the next in seconds. Each TR attachment button is also color-coded to identify its grade, making it easy to grab the grade required for different applications.
