Singer 4423 Heavy Duty Sewing Machine

Singer Heavy Duty 4423 has all the power you'll ever need. It packs the power and speed to quickly take on any sewing project, as I mentioned earlier at 1100spm. Perfect for personal tailoring projects, it is reliable, efficient and suitable for everyday use.

The 4423 is the next step up the ladder in the heavy-duty range from Singer. It offers lots of stretch stitches for ever-edging or even straight stretch for hemming or seams. Use the single dial to choose one of the 23 stitch options, including the one-step buttonhole. Other popular stitches include blind hems and reverse sewing.

Renowned heavy-duty styling and high build quality needed for years and years of trouble-free sewing. It has 23 stitch functions including many stretch stitches as well as one-step automatic buttonholes and built-in auto needle threader. It also has a lever at the rear that can quickly be moved into a position that will drop the feed dog and allow darning or free-motion embroidery.

The Singer 4423 won't win any beauty competition, but personally, I like it! It has its own individual style and Singer has designed the 4423 with simplicity in mind, threading is simple, following the numbered threading arrows. The top loading bobbin, auto de-clutch bobbin winder, and twin needle sewing option make it a good universal model for beginner to intermediate-level dressmakers or students. It also has a full range of utility and stretch stitches.

It is powerful too and packs a 90 watt motor to power it's way through multiple fabric layers. Zig zag width is 6mm for decorative patterns, with the option to adjust the stitch length up to 4mm. It is a smooth and fast stitcher at 1100spm, yet controllable, thanks to the electronic foot speed control.

The lifting handle and lightweight chassis, meaning it can be lifted into position quickly. With1-step buttonholes, overlock, blind hems, scallop, ricrac and stretch stitches, there's no stopping this 4423 heavy-duty model from Singer.
