Finding the best heavy duty sewing machine that can handle thick fabrics like leather and denim can be time-consuming because of so many models available. We have reviewed the top 5 best heavy duty sewing machines. We recommend the Singer 4423, it is more resistant to wear and tear than other models and requires less maintenance. Also, the ability to handle thick and multiple layers of fabric is impressive. 


Singer 4423 Heavy Duty Sewing Machine

The Singer 4423 heavy duty sewing machine has been one of the top-selling models for years. It’s affordable, does a fantastic job, and has impressive features for the at-home sewer.

Types of Fabrics it can handle

This machine can handle denim, canvas, and even leather. But we would not recommend it if you are looking for a thick veg-tan leatherwork machine, and you need to stack leather pieces and sew them. You need an industrial machine (a postbed) for sewing leather that dense. 

Best for day-to-day sewing projects

With 23 built-in stitches, the Singer 4423 is the best heavy duty sewing machine for day-to-day sewing projects. Out of those 23 built-in stitches, it has 12 decorative stitches that you can use to create unique patterns. However, if you are looking for a heavy-duty sewing machine for more demanding projects, you should consider other models we have reviewed.
