One of our most popular machines in the UK

Heavy Duty - up to 1100 stitches per min.
60% stronger, 30% faster, Auto threader, Drop Feed for free motion embroidery



The Singer Heavy Duty 4423 is a fully automatic, high-powered sewing machine with a maximum sewing speed of 1,100 stitches per minute to make light work of those bigger tasks.

The 60% more powerful motor makes it able to sew through heavy weight fabrics and pierce thick seams with ease, working well with everything from silk right through to leather. 30% faster movement means that repetitive work can be overcome in a fraction of the time it otherwise would.

Built to last, the metal interior frame and stainless-steel bedframe offer continuous stability and exceptional durability so you can continue crafting for many years to come.

This Singer heavy duty sewing machine has an auto threader for simple rethreading, allowing you to easily thread through the eye of a needle without stress or strain.

The easy-to-use drop feed allows for free motion sewing and embroidery, and the Free Arm means you can sew collars, cuffs, and other tubes into your project.

We love the 4423, at Singer Outlet, for its industrial look and feel but with those creature comforts of a home machine that make it so simple to use.

    singer 4423

    an excellant machine and very strong copes with all sorts of materials, and very fast stitching. good value for money

    Rae Bates (Folkestone, GB)
    Singer Heavy Duty Sewing Machine

    Pleased with stitching so far. Have not yet worked out how to use the needle threader - doing this by hand is quite fiddly, I have small hands and there is really not enough space to get close enough to the needle when threading.

    Great machine. Customer service was also awesome

    Jane Selby (Manchester, GB)
    Sturdy work horse

    I bought this machine because my current sewing machine could not handle an upholstery job I was doing. Very pleased with the quality, smooth running and no nonsense approach this machine offers. Got my job done perfectly. I bought the extension table which is also sturdily built and a must when work with heavier fabrics. Very pleased with my new Singer. Should have bought this one initially. Excellent price. Very, very happy!
