This is a sampling of our now famous "Klingspor Gold" rolls. They're made with premium Aluminum Oxide grains, resin-bonded to a very flexible Egyptian cotton backing which makes it ideal hard-to-sand, highly contoured work. With our proprietary gold top-coating, you'll realize cooler sanding/cutting and reduced loading so the Gold Rolls can be used in various wood sanding applications from carving to woodturning. Klingspor Gold is also great for work on stainless steel, tool steel and high alloy steels with its cool cutting properties. It can be used on other ferrous metals and non-ferrous metals, which makes it a great option for sharpening. The Gold Roll Sampler 8 Pack includes 2" wide by 12" long strips of grits 80, 100, 120, 150, 180, 220, 320 and 400.
