Enjoy consistent performance and save money using this Gemini ALU A AO Type 01/41 chop saw cut-off wheel. Perfect for use on aluminum, this wheel features an aluminum-oxide abrasive and an abrasive and bond combination that provide a smooth, clean cut when using low horsepower chop saws. The sides of the wheel are reinforced with a harder grade for longevity when cutting small cross-sections, meaning it costs less money per cut.
