BERNINA L 620 Coverstitch Machine
Professional hems. Effortless threading. Exceptional BERNINA control.
The BERNINA L 620 brings professional coverstitch finishing into your sewing room with an impressive combination of easy threading, precise fabric control and thoughtful convenience features.
Designed for beautiful coverstitch and chainstitch sewing, the L 620 is ideal for hemming T-shirts, activewear and knit garments, attaching bindings, sewing elastic, creating decorative topstitching and giving handmade clothing the polished finish you see on ready-to-wear garments.
With the One-Step BERNINA Air Threader, built-in needle threader, Free Hand System, 120 mm of workspace and speeds up to 1,200 stitches per minute, the L 620 makes professional finishing easier and more enjoyable.
What Is a Coverstitch Machine?
If you've ever looked at the bottom of a professionally made T-shirt, you've probably seen a coverstitch.
The familiar parallel rows of straight stitching on the front with a flexible looper stitch underneath create a clean, professional hem that can stretch along with knit fabric.
That's exactly what the BERNINA L 620 is designed to create.
Unlike a traditional overlocker that trims and finishes raw fabric edges, the L 620 specializes in coverstitching and chainstitching.
That makes it an excellent companion to your sewing machine and overlocker—especially if you make clothing.
One-Step BERNINA Air Threader
Threading doesn't have to be the difficult part of using a coverstitch machine.
The L 620 features BERNINA's One-Step Air Threader, allowing you to thread the looper quickly and easily.
Even better, the air-threading area is illuminated, making the threading path easier to see.
The machine also features a built-in semi-automatic needle threader, helping simplify needle threading as well.
Together, these features remove much of the intimidation traditionally associated with threading a coverstitch machine.
Professional Coverstitches
The L 620 creates both 3-thread and 4-thread coverstitches, giving you multiple options for professional hems and decorative stitching.
Coverstitch is especially useful for:
• T-shirt and knit hems
• Leggings and activewear
• Sweatshirts
• Children's clothing
• Neckline and armhole bindings
• Attaching elastic
• Decorative topstitching
• Stretch fabrics
• Ready-to-wear garment finishing
The flexible stitch construction allows your finished seam to stretch with the fabric—an important advantage when sewing knits and activewear.
2-Thread Chainstitch
The L 620 isn't limited to coverstitching.
Its 2-thread chainstitch provides another versatile sewing option for joining seams, basting, topstitching and decorative work.
Chainstitch can be particularly useful when you want a strong seam with additional flexibility or a distinctive decorative appearance.
Differential Feed
Stretch fabrics can be challenging because they may stretch, wave or distort as they're sewn.
The L 620's adjustable differential feed lets you control how the fabric moves through the machine.
Use it to help produce smooth, flat seams on knits—or intentionally adjust it to create gathering and other effects.
It's one of the most important features for achieving professional results when sewing stretchy fabrics.
120 mm of Working Space
BERNINA gives the L 620 an impressive 120 mm of space to the right of the needles.
That additional room is especially valuable when you're topstitching farther away from a fabric edge or maneuvering larger garments through the machine.
BERNINA also includes a Slide-on Table for additional project support.
Even better, the table includes a matching coverstitch insert with seam markings, helping you guide your fabric accurately while hemming and coverstitching.
Free Hand System — FHS
One of the L 620's standout convenience features is BERNINA's Free Hand System (FHS).
Use the knee lever to raise the presser foot without taking your hands away from your project.
On the L 620, activating the FHS also lowers the feed dog, making it easier to position or remove fabric underneath the presser foot.
This is particularly useful when you're trying to precisely align a hem, binding or other detailed garment area.
Programmable Needle Stop
Choose exactly how you want your machine to behave when you stop sewing.
The L 620 offers a programmable needle stop up/down, letting you choose whether the needles remain in the fabric or return to the raised position.
You can also use the back-kick function of the BERNINA foot control to raise or lower the needles.
It's a small feature that provides noticeably more control when you're sewing around curves or carefully positioning a garment.
Up to 1,200 Stitches Per Minute
The L 620 can sew at speeds up to 1,200 stitches per minute, allowing you to finish long hems quickly.
But you don't have to sew at full speed.
A conveniently positioned speed control slider lets you set the machine's maximum speed, while BERNINA's foot control gives you precise control all the way down to individual stitches.
A powerful DC motor helps provide consistent performance whether you're sewing quickly or working slowly through a detailed section.
Swing-Out Presser Foot
Changing needles and accessing the sewing area is easier thanks to the L 620's swing-out presser foot.
The foot moves out of the way to give you better access to the needles.
The two-step presser-foot lift also provides additional clearance for positioning thicker or multilayered projects underneath the foot.
Clear Cover/Chainstitch Foot #C28 Included
BERNINA includes the Clear Cover/Chainstitch Foot #C28 with the L 620.
Its transparent design provides a better view of your fabric and needle area, making it easier to follow markings and accurately position your stitches.
That's especially useful for decorative coverstitching, topstitching and other techniques where precise placement matters.
Bright, Adjustable Lighting
The L 620 features six LED lights to brightly illuminate the sewing and threading areas.
The sewing light is also dimmable, allowing you to adjust the brightness to suit your workspace and project.
BERNINA even illuminates the air-threading area—another small but thoughtful detail that makes setup easier.
