One-Step BERNINA Air Threader

Place the thread at the threading nozzle and use the foot control to activate the One-Step BERNINA Air Threader. Air carries the looper thread through the machine for you, while illumination shows you the operating status.

Because the system is activated with the foot control, both hands remain free to position the thread.

The threading paths are also colour coded, and the new magnetic all-in-one looper cover gives you quick access when preparing the machine.

Built-In Needle Threader

The L 660 also has an integrated needle threader located at the needle area. It switches between the needles, helping take care of another fiddly part of setting up an overlocker.

BERNINA Free Hand System with Feed Dog Drop

Use the knee lever to raise and lower the presser foot while keeping both hands on your fabric. When the presser foot is raised with the FHS, the feed dog lowers at the same time, creating additional space underneath the foot and making it easier to position or remove your project.

Micro Thread Control for a Better Fabric Edge

BERNINA's Micro Thread Control, or mtc, lets you fine-tune the amount of looper thread wrapping around the cut edge of your fabric.

You can even make the adjustment while you're sewing. This gives you much finer control over how the finished seam sits against different fabrics.

Differential Feed for Knits, Fine Fabrics & Gathering

The L 660 has continuously adjustable differential feed from 0.7 to 2.

From Stitch-by-Stitch Control to 1,200 Stitches Per Minute

The L 660's DC motor and BERNINA foot control allow you to sew slowly and precisely when you're navigating a curve or detailed section, right through to a maximum speed of 1,200 stitches per minute when you're ready to move.

The programmable needle stop lets you choose whether the needle stops up or down, while the back-kick function on the foot control can raise or lower the needle.

18 Overlock Stitches

The L 660 gives you 18 stitch variations for construction, finishing and decorative work.

These include 4-thread overlock for strong stretch seams, 3-thread overlock in wide and narrow variations, super-stretch stitching, flatlock, narrow seams, rolled hems, picot stitching and a range of 2-thread stitches.

4-Thread Overlock

The classic choice for strong, durable and elastic seams. It's particularly useful for constructing knit garments, sportswear and other projects where the seam needs to stretch with the fabric.

Rolled & Narrow Hems

Create neat, fine edge finishes for lightweight fabrics, ruffles, scarves, blouses and decorative projects.

The L 660 provides particularly fine stitch-length adjustment between 0.8 and 1.5mm, giving you more control when perfecting rolled hems on delicate fabrics.

Flatlock & Decorative Overlocking

Flatlock stitches and decorative threads can turn the seam itself into part of your design, opening up possibilities for sportswear, patchwork, decorative clothing and creative textile projects.

Adjustable from Fine Fabrics to Heavier Projects

Presser foot pressure can be adjusted to suit different fabric weights, while the overlock width can be set anywhere from 3–9mm.

The two-step presser foot lift provides extra clearance when you're positioning thicker or multi-layered projects.

The presser foot itself can also swing out to the side, giving you easier access when threading the needles, changing needles or positioning thread underneath the foot.

Thoughtful Storage & Included Accessories

The L 660 includes an accessory box with an integrated tool insert to keep smaller accessories organised.

The included Overlock Foot with Tape Guide #L11 has an open tape guide and can be used across fabrics from fine through to heavy, making it useful when incorporating tape into your overlocked projects.

An Overlocker Designed to Be Used

BERNINA L 660 makes a particularly strong case for itself. Air threading removes much of the frustration traditionally associated with threading the loopers, the built-in needle threader tackles the needles, and BERNINA's Free Hand System, speed control, differential feed and mtc give you considerably more control once you start sewing.
