BERNINA L 660: Fast, Precise Overlocking

The L 660 is the air-threading overlocker in the BERNINA L series, built for fast and clean finishing. Reserve one with a $500 fully refundable deposit and pick it up at your Quality Sewing store when it arrives. (This machine is only available for in-store pickup.)

Professional Overlocking

The BERNINA L 660 creates clean, professional seams, rolled hems, and flatlock using 2, 3, or 4 threads, with 18 stitch patterns at up to 1,200 stitches per minute. A powerful, quiet DC motor delivers consistent piercing power on any fabric.

BERNINA L 660 Overlocker (Serger) - Effortless Air Threading

Effortless Air Threading

  • One-Step BERNINA Air Threader for the loopers
  • Color-coded one-path threading
  • Same threading paths for every stitch

Hold the threads over the air threader, press the foot control, and the threads are drawn in by air. With the needle stop up, the loopers move to the correct position automatically, no handwheel turning required.

Differential Feed and Micro Thread Control

  • Stepless differential feed, 0.7 to 2
  • mtc Micro Thread Control
  • Smooth, pucker-free seams

Stepless differential feed keeps delicate and stretchy fabrics smooth and free from puckering, while Micro Thread Control fine-tunes the looper thread for perfectly balanced stitches, even while you sew.

BERNINA L 660 Overlocker (Serger) - BERNINA Free Hand System

BERNINA Free Hand System

  • Knee lifter raises the presser foot
  • Drops the feed dog at the same time
  • Both hands stay free to guide the fabric

The built-in Free Hand System lets you raise the presser foot and drop the feed dog with a knee lifter, giving you more clearance and full control when positioning even the thickest fabrics.

Programmable Needle Stop

  • Needle stop up or down
  • Stitch-by-stitch sewing
  • Back-kick foot control

Program the needle to stop up or down, and use the back-kick on the BERNINA foot control to raise or lower the needle by half a stitch for precise starts and stops.
