The Singer Heavy Duty 4423 Sewing Machine is designed for both durability and versatility, featuring a full metal frame that provides internal stability and long-lasting performance. With an extra high sewing speed of up to 1,100 stitches per minute, this machine is perfect for tackling larger projects that require long seams or seam finishes. Enhanced piercing power from a stronger motor allows for seamless sewing through multiple layers and thicker fabrics, making your sewing tasks easier. The generous "C" space between the needle and the main part of the machine gives you ample room to manage bigger projects effortlessly.

This machine offers 97 stitch applications, providing a wide array of sewing techniques for creative and customized projects. You can easily select your desired stitch using the Stitch Selector Dial, which clearly displays each option. The one-step buttonhole feature simplifies the buttonhole sewing process; you just place the button in the foot's holder, and the machine sizes the buttonhole perfectly. The stainless steel bed plate allows fabrics to glide smoothly, while the convenient needle threader helps you thread effortlessly. The top drop-in bobbin comes with a clear view cover, offering a jam-proof experience and easy monitoring of thread supply. Furthermore, adjustable features such as tension and presser foot pressure ensure your sewing remains precise, whether you're working with delicate or heavy fabrics. The StayBright LED lighting brilliantly illuminates your workspace, eliminating shadows for better visibility. The drop feed lever allows for versatile sewing options like free-motion techniques, and the free arm capability lets you easily sew cuffs, collars, and hems. With adjustable stitch length and width, you can tailor your settings to suit any project perfectly.
