Flexible Diamond Velcro Backing Sanding Disc

Metal Bond Resists Wear and Anchors Diamond Metal Bond securely anchors micron-graded diamonds to a flexible cloth backing in an open dot pattern. Metal Bonds are known to be tough and durable binding agents when it comes to adhering mineral to a backing. How to Identify the Three Open-Dot Patterns flexible Diamond Velcro Cloth Disc comes in three patterns: D1, D2 and D3. Here's how to distinguish between the three. Pattern D3 is a small-dot pattern, designed for finer finishes, grade for grade D2 is a medium-dot pattern designed for aggressive cutting action. It has improved coolant flow, given the spacing of the dots Pattern D1 is the largest dot pattern and it's ideal for applications where loading is a problem. The gaps in the mineral design allow swarf and debris to escape Overall, the open dot pattern whether tight or condensed delivers aggressive cutting action while reducing loading. Given its dual strength and flexibility, the flexible Diamond Velcro backing Cloth Disc is a great abrasive for your hard to grind materials.Importantly, this diamond abrasive with a Velcro (hook and loop) backing for easier attachment. The hook and loop backing allows swift and easy change-out of Disc, especially when the task requires multiple discs in a sequence. Recommended Applications Glass grinding and edge seaming Fast leveling on stone inlay, glass, ceramic Polishing stone, gems, composites, concrete and metal Removing deep scratches in stone, glass or composites left by previous steps Hard to grind materials
