Singer Heavy Duty 6700C: Computerized Power for Thick Fabrics
The Singer Heavy Duty 6700C is a computerized sewing machine with 411 stitch applications, one lettering font, seven one-step buttonholes, and 6.4 inches (163 mm) of sewing space between the needle and the tower. It is built to handle heavy fabrics and still sew lightweight sheers. The machine measures 17.3" x 7.5" x 10.9".
Power for Thick Fabric Layers
Singer designed the 6700C with heavy duty projects in mind, from denim to canvas. A powerful motor and a heavy duty metal frame handle thick layers. Fabric glides over a stainless steel bed plate, and adjustable presser foot pressure lets the machine sew lightweight sheers. The 6.4" of sewing space suits larger projects.

High-Speed Stitching at 1,100 SPM
High-speed stitching at 1,100 stitches per minute saves time, and the speed control sets the maximum sewing speed for the project.

411 Stitch Applications, Lettering, and Buttonholes
Choose from 411 stitch applications with touch-button selection, plus one lettering font for words, phrases, and monograms (letters sew at 7 mm, slightly more than 1/4 inch). Seven one-step buttonhole styles size themselves to your button, and the LCD screen shows the selected stitch and its settings and recommends the presser foot.

Needle Threader, Tie-Off, and Drop-In Bobbin
A built-in needle threader threads the needle eye. The tie-off button secures a stitch and stops sewing, and it can be programmed to tie off at the end of a stitch. Under its clear cover, the top drop-in bobbin uses SINGER Class 15 transparent bobbins.
10 Presser Feet and Accessories Included
Ten feet come in the box, including an even feed walking foot, a Sew Easy foot, a cording foot, and a blind hem foot, along with four bobbins, spool holders, needles, and a soft cover.
