The SINGER HD0450S Heavy Duty Serger conquers any fabric with ease. It expertly sews seams and finishes simultaneously, trimming excess fabric for a clean edge. Boasting a 60% larger cutting knife, it powers through thicker materials, supported by a robust metal frame for skip-free stitching. A stainless steel bedplate ensures smooth fabric glide, while the color-coded threading system simplifies setup. Adjustable differential feed prevents puckering and allows for creative gathering on knits, granting projects a professional, store-bought finish.
