Automatic Needle Threader

Threading the needle is a breeze with the built in Automatic Needle Threader! Not only is it a great time saver, but it eliminates eye strain when placing the thread into the needle. The hook pulls a thread loop through the needle’s eye. When you release the lever, just pull the loop and you’re done. You’ll wonder what you ever did without it!

Top Drop-In Bobbin

The Top Drop-in Bobbin makes bobbin threading fast and easy! The bobbin and bobbin cover are both transparent making it easy to monitor your thread supply. Just place the bobbin into the bobbin case, thread the guides, then draw up the bobbin thread. Snap the cover in place and you’re ready to sew. The top drop-in bobbin is also jam-proof so your sewing is worry-free!

23 Built-In Stitches

The SINGER 4423 Heavy Duty sewing machine features 23 built-in stitches. Choose from a great selection of essential, stretch and decorative stitches as well as a fully automatic 1-step buttonhole. You’ll find the perfect stitch for any project!

More Powerful Motor

Sew those long seams in no time with the SINGER 4423 Heavy Duty sewing machine. This machine has a more powerful motor, and it sews faster than most other sewing machines! Whether you want to sew fashions or home décor, you’ll do more in less time thanks to the higher stitch speed of this great machine.

Drop Feed

Feed Dogs are located under the presser foot of the sewing machine. Feed Dogs move from front to back in a ‘rotating’ motion, to move the fabric through the machine as you sew. Conveniently located at the back of the machine, the Drop Feed Lever lowers the feed dogs. Disengage the feed dogs when free-motion sewing, so you can move the fabric manually.

Professional Buttonhole

Create buttonholes for your projects in one easy step! Just set the machine for the buttonhole, place the button onto the Buttonhole Foot and the machine does the rest! Every buttonhole is perfectly sized for your button, no matter how many buttonholes you want to make. You’ll have professional looking results every time, in one easy step.

Heavy Duty Metal Frame

The SINGER 4423 Heavy Duty sewing machine's inner frame is constructed of heavy duty metal. It provides rigid support holding all the mechanisms in perfect alignment for skip-free sewing and overall durability. It’s built for years of extended use.
