Singer Heavy Duty 4432: Metal Frame Power for Thick Fabrics
The Singer Heavy Duty 4432 is a mechanical sewing machine with 110 stitch applications, 32 built-in stitches, and a one-step buttonhole. It has 6.25 inches of space to the right of the needle, and it is built for heavy duty projects from denim to canvas.
Singer's Online Owner's Class covers threading, selecting stitches, and making a buttonhole, and the SINGER Sewing Assistant App covers machine parts, set-up, and stitch selection.

Heavy Duty Metal Frame
The internal frame is heavy duty metal. It holds the mechanisms in alignment for skip-free sewing and long-lasting durability. A stainless steel bed plate lets fabric glide as you sew.

Motor Power for Denim and Canvas
A high-performance motor, 60% stronger than a standard sewing machine motor, sews at a top speed of 1,100 stitches per minute. The extra-high presser foot lifter makes room for thick layers, and adjustable presser foot pressure also handles lightweight sheers.

110 Stitch Applications and One-Step Buttonhole
Turn the stitch selection dial to choose from 32 built-in stitches, which cover 110 stitch applications. A stitch application is a specific technique you can do with a selected stitch. Place the button in the buttonhole foot, and the machine sews a one-step buttonhole sized for that button.

Needle Threader and Drop-In Bobbin
The built-in needle threader threads the needle eye without strain. A top drop-in bobbin sits under a transparent cover, so you can watch your thread supply and avoid running out mid-seam.

Costumes, Fashions, and Home Decor
Sew original costumes, personalized fashions, and decorator pillows and curtains. The free arm opens up when you slide off the storage compartment, which suits hems, sleeve cuffs, and other tubular projects.
Four Presser Feet and Accessories Included
The box includes a general purpose foot, zipper foot, buttonhole foot, and button sewing foot, plus an edge/quilting guide, needles, bobbins, spool caps, and a soft dust cover.
