6600C Sterling Edition Heavy Duty Sewing Machine
$

The SINGER® HEAVY DUTY™ 6600C Sterling combines a premium metallic finish with powerful computerized performance. Built for demanding projects, it handles thick fabrics like denim and canvas with ease, thanks to its strong motor and fast sewing speed. A generous 6.4” throat space gives you room to work, while adjustable presser foot pressure and a stainless steel bedplate make it easy to handle lightweight fabrics, too.
With 215 stitch applications, including one-step buttonholes, this machine is perfect for everything from custom costumes to home décor. The top drop-in bobbin is easy to load and monitor—so you’re never caught mid-seam without thread.
215 Stitch Applications. A stitch application is a specific technique you can do with a selected stitch. Click below to see the complete listing of Stitch Applications for this sewing machine.

Specifications
- Stitch Applications (215) – A Stitch Application simply means a specific sewing technique that you can do with a selected stitch. Basically, Stitch Applications are all the different things you can actually DO with your machine!
- One-Step Buttonhole (6 Styles) – Buttonholes are sewn in one easy step. Just place the button in the buttonhole foot and the machine sews a buttonhole perfectly sized for that button, delivering consistent results every time.
- Built-In Needle Threader (+) – Effortlessly threads the eye of the needle – eliminates eye strain and saves you time.
- Top Drop In Bobbin (+) – Easy to thread and easy to see! The transparent bobbin and cover allow you to monitor your thread supply so you don’t run out of thread in the middle of a seam.
- Drop Feed (+) – Feed teeth can be lowered for button sewing or free-motion sewing – a must-have for quilters! Simply slide the Drop Feed Lever to lower the feed teeth. Slide it back and turn the handwheel one full turn to raise the feed teeth again.
