SINGER® Heavy Duty 4423 Sewing Machine

The SINGER Heavy Duty 4423 is the straightforward, mechanical heavy duty machine: a metal frame, a stainless steel bedplate and a top speed of 1,100 stitches per minute, run from a simple dial. It has 23 built-in stitches (97 stitch applications), a one-step buttonhole and a built-in needle threader, which covers hemming, mending, garments and sturdier home projects such as canvas totes and cushion covers.

Why choose the SINGER 4423

• Dial-and-go controls. Choose a stitch with the selection dial; stitch length and width (up to 6 mm) are adjustable.
• Built for steady work. Heavy duty metal frame, stainless steel bedplate and a high-performance motor rated to 1,100 stitches per minute.
• Handles more than one fabric weight. Adjustable presser foot pressure lets you lighten the foot for sheers or press harder for denim and canvas.
• Easy everyday setup. Built-in needle threader, a top drop-in bobbin you can see through the cover, and snap-on presser feet.
• Room to lift thick layers. An extra-high presser foot lifter and a free arm for cuffs and sleeves.

The 4452 also includes a walking foot, non-stick foot, clearance plate and heavy duty needles. The 4411 is the simpler step down, with 11 stitches, a four-step buttonhole and no built-in needle threader listed.
