An industrial grade sewing machine is designed to sew especially thick fabrics that a normal machine might not be able to handle. This makes it perfect for leather, denim, thick canvas, and other heavy-duty fabrics that would normally break your sewing needles. While it is much more powerful than other machines, its abilities are much more limited, as they can typically only sew straight stitches.
