Main Features & Creative Benefits

One-Step Illuminated BERNINA Air Threader
Setting up your coverstitch machine is no longer a complicated obstacle. The revolutionary One-Step BERNINA Air Threader automatically feeds the looper thread through the machine using a puff of air. Accompanied by integrated bright LED illumination and a magnetic all-in-one looper cover, preparing to sew is intuitive, simple, and takes just seconds.

BERNINA Free Hand System (FHS) with Feed-Dog Drop
Keep your hands exactly where they are needed—on your fabric. The integrated Knee Lever allows you to raise and lower the presser foot without reaching for a back lever. Simultaneously, this smart system automatically drops the feed dogs down, providing ample physical clearance to insert or extract heavy projects and multi-layered garments without snagging delicate fibers.

Complete User-Facing Speed Control & Dimmable Workspace
Control your speed with ultimate precision. The L 620 features a powerful DC motor that delivers consistent needle-piercing power at any speed. Change your pace using the newly integrated speed slider right on the front of the machine, or stitch precisely stitch-by-stitch with the specialized BERNINA foot control featuring a needle-positioning back-kick function. A built-in dimmable sewing light lets you customize your desk illumination for a perfect creative atmosphere.

Exceptional Coverstitch and Chainstitch Quality
Sew robust 3-needle and 4-needle coverstitches that lay perfectly flat and flex effortlessly with activewear knits, lace borders, or wide waistbands. The 2-thread chainstitch is outstanding for assembling heavy denim pants or stabilizing shoulder seams. Total Stitch Control means you can dial in precise lengths, widths, and tensions for every single fabric type.

Intelligent Tool Placement & Magnetic Organization
Keep your workflow flowing without missing a beat. The built-in magnetic tool holder keeps essential scissors, pins, or tweezers safely on the face of the machine exactly where you expect them to be. Plus, the custom accessory box stores your tools and needles securely inside the table insert cover.

Expansive Workspace with Included Slide-on Table
The L 620 offers 120 mm of space to the right of the needle, allowing for smooth bulk handling. When you are stitching wide fabrics or long hems, simply attach the included extra slide-on extension table. It features a coverstitch insert complete with detailed seam markings, helping you guide your stitches straight along any fabric edge.
