Hey woodturners, is your micro size rougher's carbide insert getting dull? This is the exact replacement cutter you need. It's the genuine Easy Wood Tools Ci6-SQ, made right here in the USA. The cutter is square, measures .375 x .375 inches, and is .065 inches thick – designed specifically for their micro size rougher handles. It uses a tiny 4-40 screw to attach. The quality is top-notch: they use the perfect grade of carbide so it stays sharp longer but still cuts cleanly. The grinding process makes the cutting surfaces super flat and true, and the geometry of the cutting edge is just right for safe, smooth wood removal. Don't mess around with cheap imitations – get the real deal to keep your turning projects moving quickly and cleanly. A must-have spare for your workshop.
