BERNINA L 650 Overlocker
The BERNINA L 650 is a compact, dedicated overlocker designed to cut, stitch and finish a fabric edge in one smooth operation. It combines an illuminated One-Step BERNINA Air Threader with precise mechanical controls, a powerful DC motor and 18 stitch combinations for garment construction, edge finishing, rolled hems, flatlock effects and decorative sewing.
Built for sewists who want premium overlocking performance without unnecessary electronic controls, the L 650 offers an approachable step up from a conventional manually threaded overlocker. The loopers are threaded by air, the needle paths are colour-coded, and the presser foot swings sideways to give you better access around the needles.
Pre-order now: Australian pre-orders are currently expected to arrive in early 2027. Delivery timing is an estimate and may change. Please contact Two Petals if you would like the latest availability information before ordering.
Why Choose the BERNINA L 650?
- Illuminated one-step air threading:Â The upper and lower looper threads are carried through the threading tubes using air, reducing the fiddly work normally associated with threading an overlocker.
- Thread in your preferred order:Â The colour-coded, one-path threading system makes setup and thread changes easier to follow.
- 18 stitch combinations:Â Choose from practical 2-, 3- and 4-thread stitches for seams, edge finishes, rolled hems, flatlock sewing and decorative effects.
- Micro Thread Control: BERNINA’s mtc system lets you fine-tune the amount of looper thread wrapping around the cut fabric edge.
- Adjustable differential feed:Â Manage stretching and puckering on knits and lightweight fabrics, or deliberately gather and stretch fabric for creative effects.
- Up to 1,200 stitches per minute:Â Finish long seams efficiently while retaining the ability to sew slowly or stitch by stitch with the responsive foot control.
- Automatic needle stop up:Â When you stop sewing, the needles return to their raised position for easier fabric removal, repositioning and rethreading.
- Swing-out presser foot:Â Move the foot sideways to create more working room when changing or manually threading the needles.
- Two-step presser-foot lift:Â Extra clearance at the front of the foot helps when positioning bulky seams and multiple fabric layers.
- Externally operated knife:Â Engage or disengage the cutting knife from outside the machine when you want to sew with or without trimming the edge.
- Integrated upper-looper converter:Â Quickly prepare the machine for its range of 2-thread stitches without managing a separate loose converter.
- Useful storage details:Â A magnetic tool holder keeps small metal tools close at hand, while the accessory box organises the supplied sewing and maintenance tools.
Easy Looper Threading Without the Usual Fuss
Overlocker threading can be a hurdle for new users, particularly when the thread must pass through small guides around the loopers. The L 650 simplifies this process with its illuminated One-Step BERNINA Air Threader.
Prepare the air-threading system, position a looper thread at the appropriate nozzle and press the foot control. The thread is carried through the air tube and emerges at the looper. Both upper and lower loopers use this system, and the air-threader light helps you see the working area clearly.
The needles are threaded manually. The needle paths are colour-coded, the foot swings out of the way, and BERNINA documents a manual needle threader and inserter among the standard tools. This is different from the integrated needle-threading system offered on the higher-specification L 660.
Precise Control for Different Fabrics
Micro Thread Control
A balanced overlock stitch should wrap neatly around the cut edge without hanging loosely beyond it or pulling the fabric into a tunnel. The mtc adjustment changes the quantity of looper thread forming around the edge, allowing quick refinement without immediately changing several tension dials. BERNINA advises that mtc is most effective across cutting widths from 6 to 9 mm.
Differential Feed
The adjustable differential feed helps the L 650 handle fabrics that would otherwise stretch, wave or pucker as they pass under the foot. Increase the setting to help control jersey, sweatshirt fleece and other knits, or use a lower setting to reduce puckering on fine, densely woven materials. It can also be used intentionally to create gathering or stretched decorative edges.
Adjustable Presser-Foot Pressure
Presser-foot pressure can be adjusted for light, medium or heavier materials. This gives you another way to improve fabric feeding when moving between fine garment fabrics, everyday woven cotton, knitwear and thicker seam intersections.
Adjustments While Sewing
Thread tension, stitch length, differential feed, cutting width and mtc can be adjusted while sewing. Make small changes and test the stitch on a fabric offcut whenever you change the material, thread or number of layers.
18 Practical Stitch Combinations
The L 650 provides 18 overlock stitch combinations, including:
- 4-thread overlock with integrated safety seam
- 3-thread super-stretch
- Wide and narrow 3-thread overlock
- Wide and narrow 3-thread flatlock
- 3-thread narrow rolled seam
- 3-thread rolled hem
- Wide and narrow 2-thread wrapped overlock
- Wide and narrow 2-thread flatlock
- 2-thread rolled hem
- Wide and narrow 2-thread overlock
- Wide and narrow 2-thread blanket stitch
- 3-thread picot stitch
This selection covers strong garment seams, neat raw-edge finishing, fine hems, visible flatlock details and decorative edging. The integrated rolled-hem lever makes changing from standard overlocking to a rolled-edge setup more convenient.
What Can You Sew with the L 650?
The L 650 is designed for fabrics ranging from fine single layers to heavier multi-layer projects. Suitable applications include:
- T-shirts, tops, leggings and knit dresses
- Sweatshirts, hoodies and children’s clothing
- Activewear and other highly elastic garments
- Woven garment seams and seam allowances
- Rolled hems on lightweight fabrics
- Flatlock seams and decorative exposed stitching
- Gathered edges and stretched decorative effects
- Towelling, pile fabrics and layered seam intersections
- Neat finishing inside handmade clothing and accessories
The manufacturer’s stitch guide also provides starting-point recommendations for lightweight, medium and heavyweight woven fabrics, knits, denim, towelling, tulle, lace, pile fabrics and imitation fur. Always test the selected needle, thread and stitch settings on a project offcut first.

Needle and Thread Compatibility
Which Needles Does the BERNINA L 650 Use?
The L 650 requires ELx705-system overlocker needles . BERNINA’s documentation recommends selecting the needle size to suit the fabric, with size 80 as a general starting point for medium-weight fabric, size 90 for heavier fabric and sizes below 80 for lighter materials.
Do not assume that a standard domestic sewing-machine needle marked 130/705 H is interchangeable. Use the specified ELx705 system and contact Two Petals if you are uncertain about a particular needle pack.
Which Threads Can It Use?
Standard overlocking thread is suitable for everyday construction and finishing. The loopers can also accommodate selected bulky, textured, decorative and ornamental threads. Waxed or coated threads are not recommended in the loopers because residue can contaminate the air-threading tubes and interfere with threading.
Explore sewing and overlocking threads at Two Petals , or ask the team for help matching thread to your fabric and intended stitch.

BERNINA L 650 or L 660?
The L 650 is an excellent choice when you want the core performance of the BERNINA L 6 overlocker platform, including air-threaded loopers, mtc, automatic needle stop up, a DC motor and adjustable mechanical stitch controls.
Consider the L 660 instead if you specifically want additional convenience features such as an integrated needle threader, Free Hand System knee lifter with feed-dog drop, programmable needle stop up or down, needle control through the BERNINA foot control, a speed-control slider or dimmable sewing light. These features are not included on the L 650.
The L 650 and L 660 are dedicated overlockers. The L 620 is the coverstitch-focused model in the L 6 Series. Choose according to the stitches you actually need rather than assuming an overlocker and a coverstitch machine perform the same tasks.
Important Buying Guidance
- Choose the L 650 if:Â you want easy air threading, precise manual adjustment, 18 overlock stitches and premium garment-finishing capability.
- Choose another model if:Â you require coverstitch or chainstitch hems, an integrated needle threader, knee-operated presser-foot lifting or programmable needle-position controls.
- Allow a stable workspace:Â the machine weighs 9.7 kg and should be used on a solid, level sewing table.
- Budget for suitable consumables:Â use ELx705 needles and good-quality overlocking thread appropriate for the fabric.
- Test before starting:Â stitch recommendations are starting points; fabric construction, stretch, thickness and thread choice can all affect the final settings.
Frequently Asked Questions
Is the BERNINA L 650 suitable for an overlocker beginner?
Yes. The air-threaded loopers, colour-coded threading paths, automatic needle stop up and swing-out presser foot remove several common barriers for a first-time overlocker user. You will still need to learn how thread tension, differential feed, stitch length and cutting width affect different fabrics.
Does the air threader thread the needles too?
No. The One-Step BERNINA Air Threader threads the upper and lower loopers. The needles are threaded manually. A manual needle threader and inserter is documented among the machine’s tools, but the L 650 does not have the integrated needle threader found on the L 660.
Is the BERNINA L 650 a four-thread overlocker?
Yes. It has four spool holders and can produce 2-, 3- and 4-thread stitches. The four-thread safety seam is a versatile choice for constructing many knit garments.
Can it sew a rolled hem?
Yes. It includes 2-thread and 3-thread rolled-hem options, along with a 3-thread rolled seam and picot stitch. An integrated rolled-hem lever assists with changing the machine configuration.
Can the L 650 sew flatlock stitches?
Yes. Wide and narrow 2-thread and 3-thread flatlock combinations are included. Flatlock can be used for low-bulk joins, decorative seams and visible details, depending on the fabric and thread.
Does it do coverstitch or chainstitch?
No. The L 650 is a dedicated overlocker and does not produce coverstitch or chainstitch. If professional-looking T-shirt hems are your priority, a separate coverstitch machine such as the L 620 may be more appropriate.
Can I use it without cutting the fabric?
Yes. The knife can be disengaged using the external control. Take care that the fabric edge is positioned so it cannot extend into or interfere with the stationary knife area.
Is it suitable for jersey and stretch fabric?
Yes. The L 650 includes a 3-thread super-stretch stitch and adjustable differential feed. These features help manage elastic materials and reduce unwanted waving along knit seams.
Can it sew woven fabrics as well as knits?
Yes. The stitch guide includes applications for lightweight, medium and heavyweight woven materials. The machine can finish raw seam allowances, construct suitable seams and create rolled or decorative edges.
Can I use decorative thread in the air threader?
Selected bulky, decorative and ornamental threads can be used in the loopers. Thread must move freely through the air tubes. Do not use waxed or coated looper thread, and test unfamiliar decorative thread before beginning the project.
What needle system does it use?
Use ELx705 overlocker needles. Standard 130/705 H domestic sewing-machine needles should not be treated as a substitute unless BERNINA or Two Petals has specifically confirmed the product.
Does it include a knee lifter or speed slider?
No. The L 650 does not include the BERNINA Free Hand System knee lifter or a machine-mounted speed-control slider. Speed is controlled through the supplied foot control, allowing sewing from slow, careful placement up to 1,200 stitches per minute.
Is a slide-on extension table included?
A slide-on table is supported by the machine, but it is not listed among the standard supplied accessories in BERNINA’s 2026 L 650 manual. Australian package contents may vary, so please confirm inclusion or optional availability with Two Petals.
