Singer 4523 Heavy Duty Sewing Machine

Specially engineered to sew through multiple thick layers, tough denims, and heavy fabrics with ease, maintaining consistent stitch formation and exceptional piercing strength without stalling. Easily tailor your maximum sewing speed to fit your project requirements. Slow down for intricate corners, delicate curves, and detailed appliques, or power up to 1,000 stitches per minute for rapid straight seams. Eliminate eye strain and save time before every project. The convenient built-in needle threader quickly guides your upper thread straight through the eye of the needle in seconds. Constructed with a heavy-duty, cast metal internal skeleton, this machine maintains perfect alignment, prevents skip-stitching, and delivers rigid stability during continuous heavy sewing. Ergonomically designed with soft-touch, rubberized tactile grips on the stitch selection and length adjustment dials, providing nonslip comfort and precise control while adjusting your settings.
