The biggest reason to buy is the combination of an X-weight cloth backing and an open coat aluminum oxide grain that delivers aggressive material removal and reasonable life across wood, fiberglass and non-ferrous metals. The pack of 30, split into ten each of 40, 60 and 80 grit, makes it easy to tackle rough stock removal through initial smoothing without swapping brands.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAssorted grits:\u003c\/strong\u003e Ten belts each of 40, 60 and 80 grit let users progress from heavy stock removal to initial smoothing with a single pack.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eX-weight clothed backing:\u003c\/strong\u003e The stronger cloth backing improves tear resistance and helps the belts survive demanding sanding and stripping tasks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAluminum oxide grain:\u003c\/strong\u003e Open coat A\/O grains cut aggressively on wood and work well on lite non-ferrous metals and fiberglass for blending and shaping.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResin on resin bond:\u003c\/strong\u003e A durable bonding system resists heat and helps resist premature grit loss during heavy use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeam craftsmanship:\u003c\/strong\u003e Expertly crafted seams reduce the chance of belt breakage at the joint during continuous runs.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis pack suits DIYers, carpenters and hobbyists who run a portable 3 x 18 in belt sander and need a selection of coarse-to-medium grits for rapid material removal and initial surfacing.
