Getting started has never been so comfortable
Illuminated air threader
All-in-one magnetic looper cover
Integrated needle threader
The innovative magnetic all-in-one looper cover allows quick and intuitive threading preparation. The illuminated One-Step Bernina Air Threader and the integrated needle threader make getting started effortless so you can dive straight into your creative world.
Convenient handling
Free Hand System with feed dog drop
Swing-out presser foot
2-step presser foot lift
With the Bernina Free Hand System (FHS), you can easily raise and lower the presser foot using the knee lever while simultaneously lowering the feed dog, allowing you to position and remove your sewing project with ease. In addition, the presser foot can be swung out to the side for convenient access to the needles. Thanks to the 2-step presser foot lifter, you can position even thick or multi-layered projects effortlessly and precisely.
Sew as you like
Programmable needle stop
Adjustable speed control
Dimmable sewing light
Control your L660 exactly as you wish. With the Bernina foot control, you can sew precisely stitch by stitch, and the back-kick function lets you raise or lower the needle with ease. The speed can be adjusted using the slider on the front panel, while the presser foot pressure can be customised for thin or thick fabrics. The dimmable sewing light creates the perfect working environment. Thanks to the powerful DC motor, you maintain excellent control at all times.
Precision in every detail
Micro Thread Control (mtc)
Differential feed
Total stitch control
With Micro Thread Control (MTC), you can fine-tune the looper thread amount for a flawless fabric edge. Adjust settings at any moment to achieve perfect stitches even while sewing. The stepless differential feed keeps delicate or highly elastic fabrics smooth and free from puckering. This Total Stitch Control from Bernina gives you the freedom to create unique effects.
Everything in view and within reach
Magnetic tool holder
Accessory box with tool insert
Overlock Foot with Tape Guide #L11
The open tape guide of the Overlock Foot #L11 makes it suitable for a wide range of fabrics, from fine to heavy, and ideal for adding tape to projects. Keep tools exactly where you need them with the magnetic holder, ensuring tweezers and scissors are always within reach. The accessory box with integrated tool insert keeps everything secure and neatly organised.
