The reviewer found the wheels perform well on aluminum, brass and copper because of a proprietary abrasive blend, and they are thicker than typical discs which helps when working on auto parts and other projects that require more material removal. If you need a dedicated non-loading wheel for an angle grinder, this is worth considering.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-loading abrasive:\u003c\/strong\u003e A proprietary blend of aluminum oxide and silicon carbide helps prevent clogging when grinding soft metals like aluminum, brass and copper so the wheel keeps cutting effectively.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThicker construction:\u003c\/strong\u003e At 9\/32 in thickness the discs are thicker than many thin wheels, providing more material and stability for heavier grinding tasks on automotive parts and castings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReinforced safety:\u003c\/strong\u003e Double external fiberglass reinforcement adds tensile strength to resist breakage during high-speed use on an angle grinder up to 12,200 RPM.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesigned for angle grinders:\u003c\/strong\u003e Sized for common 4 1\/2 in angle grinders and built to handle typical workshop RPMs while offering consistent abrasive contact.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack quantity:\u003c\/strong\u003e Ten wheels in the pack give a convenient supply for repeated jobs or for shops that prefer to keep replacement wheels on hand.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis product is best for mechanics, fabricators and DIYers who frequently grind aluminum, copper or brass and need a disc that will not load up and lose cutting ability.
