Singer Heavy Duty 6600C: Computerized Sewing for Heavy Fabrics
The Singer Heavy Duty 6600C is a computerized sewing machine built for heavy duty projects, from denim to canvas. It has 215 stitch applications, 6 one-step buttonhole styles, and 6.4 inches (163 mm) of space to the right of the needle. The machine measures 17.3" x 7.5" x 10.9".
A powerful motor gives extra high sewing speed to save time, with a top speed of 1,100 stitches per minute. Fabric glides over the stainless steel bed plate, and adjustable presser foot pressure lets the machine sew lightweight sheers too.

6.4 Inches of Sewing Space
Singer calls this generous space a "C" space, and it lets you sew larger projects like quilts with ease. It also suits the heavy duty work this machine is built for, from denim to canvas, and home decor projects such as pillows and curtains.

215 Stitch Applications With Touch-Button Selection
Choose a stitch with the touch buttons, and the display shows the selected stitch and its settings. Length and width are preselected for each stitch and can be adjusted. Create original costumes, personalized fashions, or new decor for your home.
One-Step Buttonholes in 6 Styles
Place the button in the buttonhole foot and the machine sews a one-step buttonhole sized to that button. Each buttonhole comes out the same, for consistent results every time.

Slide-Out Presser Foot Chart
Slide the chart forward at the bottom right of the machine to see the presser foot recommended for each stitch. Each stitch also has a preset length and width, so the chart is a quick check before you start sewing. It is built into the machine, so the guidance is always at hand.
Needle Up/Down and Reverse Buttons
Press the needle up/down button to raise or lower the needle and set where it stops. The reverse button sews in reverse on stitches 1 to 5 and sews 3 tie-off stitches on most other stitches.

Presser Feet and Accessories Included
All purpose, zipper, buttonhole, blind hem, and satin stitch feet come in the box. Bobbins, spool holders, an auxiliary spool pin, needles, and a soft cover are included too. Slide off the removable accessory tray to reach the free arm for cuffs and trouser hems.

Top Drop-In Bobbin and Built-In Needle Threader
The top drop-in bobbin is easy to thread, and the transparent cover shows how much thread is left, so you do not run out mid-seam. A built-in needle threader threads the needle eye.
