standard size of the stainless steel cutting wheel

stainless steel cutting wheel for circular saws of standard size are 7 1/4 inches in diameter. They are made similarly to discs for angle grinders but without the cupped center washer. A diamond-shaped plate with a round hole in the center is used for mounting. flap wheels are best for light cutoff on a few pieces, or cutting sheet metal and metal paneling. Metal discs can also be used with a diamond-coated edge, with vent notches at regular intervals.
