Affordability is the name of the game with the Singer 4423. As such, it’s most certainly one of the best options on the market if you’re on a budget, or you’re a beginner that just wants to try their hand at sewing.

Whatever you choose, any one of these machines is sure to serve you well. They all feature exceptionally powerful motors and a high sewing speed. Every one of these sewing machines is durable enough to last for a long time, so your money will certainly be well spent.

The Finishing Touches

If you’re looking for a high-quality sewing machine, you should certainly consider any one of these options. If you’ve followed our site you’ll know that we LOVE these machines for their versatility and power. Even as a beginner, it’s helpful to have the versatility of a heavy duty sewing machine to reduce limits on what fabrics you can work with and how many layers your machines can handle.

When I (Jessa) first started sewing, it was all simple items with simple cotton. These days, I find myself mending denim of three kiddos, altering heavy fabrics, and creating throw pillows that need to withstand the high traffic and wear and tear of toddler years (while still looking beautiful). Heavy-duty sewing machines provide the versatility for simple projects as well as “bigger” things like creating giant princess dresses with endless layers of tulle. Um, those are for my daughter most of the time….;)

What are you waiting for? It’s time to hop online and hit that buy button already! 

Happy heavy-duty sewing.

  1. I would be interested in your opinion for a machine is best for both quilting and upholstery as well as everyday sewing. Whether it is the 3 singer heavy duty ones reviewed or something entirely different.

    1. Hi Sheryl, No matter what, I would definitely go with a heavy-duty machine. I recently tried to sew through upholstery material with a (standard domestic) Singer Confidence and broke two needles! That said, I’m partial to Singer machines – I would consider the 4432. My neighbor swears by her Janome HD 3000 so that would be the next machine I would look into. Good luck! Let me know how it goes.

  2. do you know the difference between the 4432 and the denim 6335M? I can’t find any information other than the 6935 might just be a new model number for the 4432. thanks

  3. Would any of the machines listed in the article be suitable for stitching leather or biothane (PVC coated nylon webbing) from 1/16″ to 1/4″ in thickness? I am trying to fabricate some saddle rigging which requires sewing together two pieces of material that are each about 1/8″ thick. I want to repair some horse blankets as well. I would appreciate your opinion.

    1. I think the HD Singer machines could handle this. I’m not familiar with saddle rigging and how difficult the material and structure/pattern is to work so I can’t say for sure. That said, I checked out YouTube and watched a few videos of people working with multiple layers of heavy-weight leather on the Singer HD 4423 and 4432. I recommend searching for an example on YouTube of someone working on a similar project to see how the machine handles it and if you think it would be a good fit. (I have a leather cover on one of the chairs in my house and even though my machine can handle the material, the structure of the piece is pretty challenging to work with. I have to bring it to my local upholsterer to mend it – twice already). Good luck!
