3M™ flexible diamond hand lap 6200J is a versatile hand-held abrasive that optimizes the sharp cutting action of diamond mineral to grind and finish many materials, including chilled iron, granite, carbide, composites, non-ferrous metals, thermal spray coatings and exotic alloys. Recommended applications 3M™ flexible diamond hand lap 6200J is a good match for finishing applications that require aggressive sanding, such as highlighting body-in-white automotive defects. Because diamond mineral cuts fast and sharp, 3M™ flexible diamond hand lap 6200J minimizes the level of manual pressure needed to get the job done.Comfortable hand-held designour 3M™ flexible diamond hand lap 6200J was ergonomically designed to enhance operator comfort. The contoured foam backing assists with grip, so an even level of pressure may be applied over the surface area. Additionally, because diamond hand lap 6200J is hand-held it can easily get into those stubborn, hard-to-reach areas.Benefits of an open dot patternthe diamond mineral on 3M™ flexible diamond hand lap 6200J is adhered to a premium flexible backing in an open dot pattern. The open dot pattern allows swarf to escape, so debris will not clog the mineral. This helps sustain a sharp cut and prolong abrasive service life. The premium flexible backing conforms to the substrate and responds to surface irregularities, so you can finish contoured surfaces. 3M™ flexible diamond hand lap 6200J comes in a variety of grades tailored to meet specific project needs. Metal bond grades are available in 250, 125, 74, 40, 20 and 10 microns. Bigger microns signal bigger minerals, so these grades are good for heavy, fast stock removal. Smaller grades are best for fine finishing. Overall, our 3M™ flexible diamond hand lap 6200J is a great multi-purpose tool for any workshop.
