3M™ Flexible Diamond Family 6451J

Our 3M™ Flexible Diamond Belt 6451J is ideal for blending and finishing contours on thermal sprays, ceramics, carbides, composites, chilled iron, non-ferrous metals, and other hard to grind materials. The high flexibility of the backing is excellent for lighter duty applications such as blending and finishing, even on extreme contours.

6451J has the most flexible backing, used for lighter duty applications, such as blending and finishing Contours

Excels at Light-Duty Applications on Contours
Striking a balance between strength and conformability, our versatile 3M™ Flexible Diamond Belt 6451J conforms well to contours on hard to grind materials. It’s best for lighter duty applications, such as blending and finishing contours, and it may be used on thermal sprays, carbides, composites, chilled iron, non-ferrous metals, glass and other hard-to-grind materials.

Built Tough, Finishes Fine
We adhere the diamond abrasive on 3M™ Flexible Diamond 6456J using a metal bond. Compared to resin or vitrified bonds, metal bonds tend to be the most tough. The backing is the most flexible backing type of our 3M™ Flexible Diamond products, which helps the abrasive respond well to surface imperfections and contours.

Our Open Dot Pattern: What Does it Mean? 
The open dot pattern on each 3M™ Flexible Diamond abrasive product means that the diamond mineral particles are adhered to the backing in a series of small dots. This is designed to provide aggressive cutting action while also allowing consistent space for evacuation of swarf during sanding, helping reduce loading and prolonging the life of the abrasive surface without sacrificing cut rates.

3M™ Flexible Diamond Belt 6451J is available in two open dot patterns for a range of uses. Pattern 18 is a small dot pattern equating to 25 pellets per inch. Our B2 Pattern has medium dots with 17 pellets per inch, and is designed to deliver an aggressive cutting action with improved coolant flow and increased swarf removal. Generally, the smaller dot patterns will be the least aggressive and produce finer finishes, whereas the larger dot patterns will be more aggressive for stock removal.

Recommended Applications

• Lightweight applications on backstand or benchtop sanders
• Contour sanding
• Finish sanding

3M™ Roloc™ Flexible Diamond Disc 6234J

• Provides aggressive cutting for hard-to-grind material
• Open-dot abrasive pattern discourages loading
• Abrasive construction provides durability and long life, allows conformance to contours
• Quick-change twist-on and off Roloc™ Discs make grade changes easy, minimize downtime

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.
