BERNINA L860 Overlocker Product Review & Demonstration
The BERNINA L860 is a large, computerised overlocker combining cutting-edge technology with user-friendly design. Designed for sewers who work across a wide range of fabrics, it brings together air threading, touchscreen control and the precision tension engineering BERNINA are known for. Whether you're working on garments, home décor, or creative accessories, the Bernina L860 ensures professional-quality finishes with ease. Built for versatility and efficiency, this machine is a must-have for modern sewers and creative makers.
At 1,500 stitches per minute, the L860 is fast, quiet and built to handle extended use without compromising on stitch quality. The one-step BERNINA Air Threader handles both loopers with a step on the foot control and the built-in needle threader completes the process without any hand threading required. The colour-coded threading path guides you through the full set-up - it really is effortless to set up.
Stitch control on the L860 is handled through a 4.3-inch colour touchscreen, with both Expert Mode for experienced sewers and Guided Mode for those working through less familiar stitch types. The Stitch Optimiser suggests the best settings for your chosen stitch and Personal Memory stores up to 100 individual stitch configurations so your preferred settings are available at any time. Micro Thread Control (MTC) gives you fine adjustment of the over-edge thread length, which is particularly useful on decorative stitches and rolled hems where the finish needs to be exact.
The L860 covers 18 stitch variations including 4-thread overlock, 3-thread super-stretch, flatlock, rolled hem, picot stitch and blanket stitch, with 2, 3 and 4-thread configurations throughout. Adjustable differential feed handles knits and jersey without stretching and fine wovens without puckering, so consistent seam quality is achievable across a wide range of fabrics. The freearm capability is perfect for sewing sleeves, cuffs and tubular items or intricate projects. Finally, the included BERNINA Free Hand System (knee lifter) keeps both hands on the fabric during operation.

Materials and Build Quality
Enjoy effortless threading with one-touch air technology that quickly threads the loopers for you. A built-in needle threader and clear colour-coded guides make setup fast, simple and stress-free.
Micro Thread Control (MTC) allows you to fine-tune the over-edge thread length for precise and flawless seam edges. Thread tension releases automatically when the presser foot is raised and tension is adjustable while sewing so corrections can be made mid-project without stopping.
The machine runs at up to 1,500 stitches per minute with a 6-step adjustable presser foot pressure system. Two LED sewing lights illuminate the needle area clearly and the safety switch prevents operation when the cover is open or the presser foot is raised.
The Difference is in the Details
At 1,500 stitches per minute, the L860 works through seams quickly without any loss of accuracy. The knife can be engaged and disengaged from outside the machine without opening the cover and the cutting width is adjustable while sewing so you can make changes without stopping. Needle stop up/down is programmable and stitch-by-stitch sewing is available for detailed or delicate work.
Expert Mode gives experienced sewers direct access to all stitch settings, while Guided Mode walks you through set-up for less familiar techniques. The Sewing Studio is an authorised BERNINA retailer. Call, chat or email for advice at any point before or after purchase.
The L860's on-screen tutorials and helpful animations mean you can learn the machine's full capability without reaching for the manual. The Creative Sewing Consultant guides you through the best settings for each technique, so you have expert input at any point in the project. The Stitch Optimiser takes the guesswork out of stitch selection by recommending the best settings for your chosen technique, which means less time troubleshooting and more time sewing.
The BERNINA Free Hand System (knee lifter) raises and lowers the presser foot without using your hands, so fabric stays positioned while you work. The swing-out presser foot with auto swing-back makes both threading and cleaning straightforward. The rolled hem lever is integrated under the stitch plate, so switching to rolled hem requires no separate attachment.

Frequently Asked Questions
Let us help with the answers.
How does the BERNINA Air Threader work and does it thread all the threads?
The Air Threader handles both loopers with a single press on the foot control, using a pneumatic system to pass thread through each looper path instantly. It does not thread the needles, but the built-in needle threader takes care of those, so the full threading process is covered without any hand threading.
What is Micro Thread Control and when would I use it?
Micro Thread Control (MTC) adjusts the length of the over-edge thread, giving you precise control over how the thread sits at the fabric edge. It is most useful on rolled hems, picot stitches and other decorative finishes where the edge quality is visible and needs to be consistent.
Can the L860 handle stretch fabrics like jersey and knits?
Yes. The adjustable differential feed is designed specifically for this. Increasing the differential feed ratio prevents jersey and knitted fabrics from stretching during stitching, so seams lie flat rather than rippling. The feed is adjustable while sewing, so you can make corrections as you go without stopping the machine.
What is the difference between Expert Mode and Guided Mode?
Expert Mode gives you direct access to all stitch settings on the touchscreen, which suits sewers who are familiar with the machine and want full manual control. Guided Mode takes you through the settings step by step, which is useful when working with a stitch type you have not used before or when you want confirmation that the settings are correct for a specific technique.
Does the L860 come with an extension table?
Yes, a slide-on extension table is included in the box. It attaches to the freearm to increase the working surface for larger projects. Removing it gives you the freearm configuration for tubular sewing on sleeves, trouser legs and cuffs.
Our standard width fabric can be cut as a Fat Quarter, measuring 50cm x 1/2 the width of the bolt. Above is an example of how your fabric will be received, depending on the quantity ordered.
We also offer a sample service, where you can order 1 single fat quarter of any standard width fabric, to have at home and compare colours. When you are finished, you can send them back to us for a refund (feel free to contact us for more information on this service).
Our fabric can be cut as a Long Quarter, measuring a minimum of 25cm x width of bolt. We will supply the fabric as a continuous length (eg; if you bought 1.25m it will be sent as one piece of fabric).
