That is where the Bernette B48 Funlock coverstitch serger comes in: a versatile workhorse designed for sewists who demand professional results at home. In this review, we evaluate the B48 and five other Bernette models to help you decide which one fits your sewing style. Whether you are a beginner or a seasoned pro, our guide covers key features, performance, and value. For a broader look at top machines, check out our guide to the best sergers and overlock machines for every sewist in 2026.
Buying Guide
Stitch Versatility and Types
When choosing a serger, the range of stitches matters for the projects you love. The Bernette B48 offers 23 built-in stitches, including overlock, coverstitch, chain stitch, and combo options. This variety lets you finish seams, hem knits, and add decorative touches on one machine. If you primarily sew stretch fabrics, a dedicated coverstitch machine like the Bernette b42 might suffice. But for maximum flexibility, a combo model like the B48 saves you from switching machines mid-project. For more on combo machines, see our best serger coverstitch combo machines for 2026.
Ease of Threading and Setup
Threading a serger can be intimidating, but Bernette has made strides with color-coded paths and mechanical threaders on the B48. For even faster setup, the Bernette B64 and B68 Airlock models feature automatic air threading, which simplifies looper threading with a puff of air. If you value convenience and speed, an air-threading model is a game-changer. Beginners will appreciate the B48 manual threader, which is straightforward once you follow the guides.
Speed and Motor Power
All the Bernette models reviewed here sew at up to 1300 stitches per minute, which is fast enough for production sewing and large quilts. The B48 and B68 have heavy-duty motors that handle thick fabrics without stuttering. If you plan to sew through multiple layers of denim or canvas, look for a model with adjustable presser foot pressure, like the B48 or B68. This feature ensures even feeding and prevents skipped stitches on bulky seams.
Lighting and Workspace
Good lighting reduces eye strain and improves accuracy, especially on dark fabrics. The B48 includes a bright LED light, while the B68 takes it further with five LED lights for full coverage. An extension table is included with the B64 and B68, giving you more room for quilting or large projects. Consider your typical workspace: if you sew in low light, prioritize models with multiple LEDs.
Final Thoughts
After evaluating these Bernette sergers, we recommend the Bernette B48 Funlock Serger Coverstitch Overlock for sewists who want a versatile combo machine with 23 stitches and a balance of features and price. It handles everything from garment construction to quilting with ease. If you prioritize speed and air threading, the Bernette B64 Airlock Serger Overlocker with Air offers advanced convenience and a free hand system for hands-free presser foot control. Both machines deliver professional results, so choose based on your budget and need for automated threading.
