A common question is how the bernette 64 AIRLOCK compares with the Bernina L 860, and which overlocker to buy. Both are air-threading overlockers that can run 4-, 3-, and 2-thread stitches, and both include a free arm plus micro thread control (MTC) for fine-tuning the looper thread on the fabric edge. bernette and Bernina sit in the same wider company family, but these two machines are aimed at different budgets and comfort levels.

Differences: Bernina L 860 vs bernette 64
Air threading works on both, but the controls feel different. On the bernette 64, a push button drives air through the threading path. On the Bernina L 860, a stepper-motor system uses the foot control to shoot the thread through. Neither is hard once you learn it. Preference comes down to which motion feels natural when you rethread mid-project.
Needle threader
Both include a needle threader, in different forms. The L 860 has a needle threader built onto the outside of the machine. The bernette 64 uses a more conventional manual-style overlocker threader. If you rethread needles often or dislike fiddly needle eyes, the Bernina setup is more convenient. It is not a reason to dismiss the 64 if the price difference is large.
Screen and guided setup
The biggest practical gap is the screen. The Bernina L 860 has a color display with guided mode that walks you through stitch changes: presser foot up, knife position, tensions, and related steps, with video help on the machine when you need a reminder. The bernette 64 has no screen. When you change stitch types you set tensions, stitch length, and stitch width yourself, usually with the manual nearby until the settings become muscle memory.
That means the L 860 is easier if you switch between overlock setups often or dislike memorizing charts. The 64 asks for more user knowledge, and rewards you with a lower price for similar core overlocking jobs.
Which overlocker should you pick?
Both are capable air-thread overlockers. The bernette 64 is the stronger value for sewists moving up from a basic serger who are willing to manage settings manually. The Bernina L 860 costs more and feels more advanced day to day because of the guided screen, smoother drive feel many users notice, and the external needle threader. Soft US pricing usually puts the 64 well below the L 860. If you can, try both in a shop. Air threading and foot feel are personal, and that short test often decides it better than a spec sheet.
