The Singer Heavy Duty 4423 is engineered for everyday sewing on tough fabrics like denim, felt and faux leather. Its motor delivers 60 % more power than standard models, enabling high‑speed sewing up to 1,100 spm. The solid internal metal frame ensures long-term precision and the stainless steel bed plate offers scratch resistance and smooth fabric glide.
Stitch selection is via a manual dial offering 23 stitch options, with adjustable stitch length and width up to 6 mm. The one-step buttonhole creates consistent buttonholes with minimal effort. Other smart features include an automatic needle threader, drop‑feed system for free‑motion work, and extra‑high presser foot lift for thick layers. The integrated free-arm simplifies sewing cuffs and tubular garments.
