7 Best Bernette Overlock Sewing Machines of 2026

The Bernette B62 Airlock isn’t just a coverstitch machine—it’s a precision powerhouse built for sewists who demand professional-grade hems without the industrial footprint. With its automatic air threader, 5 LED lights, and LCD display, setup is fast and frustration-free, making it a dream for quilters and garment makers tackling delicate knits or thick layers. The Free Hand System (FHS) stands out as a game-changer, allowing hands-free presser foot control via a knee lifter—ideal for managing large fabric spans with surgical accuracy. If you’ve ever struggled with alignment on stretchy fabrics or lost visibility in shadowed seams, this machine erases those pain points with confidence.

In real-world use, the B62 delivers clean, consistent coverstitching across everything from lightweight jersey to denim-weight knits, thanks to its robust motor and solid frame. It supports 4 coverstitches and 3 chainstitches, giving you flexibility for decorative finishes, rolled hems, and twin-needle effects. The 7-piece coverstitch foot kit expands creative control, enabling perfect topstitching, blind hems, and decorative edges. While it excels in coverstitch tasks, it’s not a full serger—so if you need simultaneous overlocking, you’ll need a combo machine. Still, for pure coverstitch performance, it’s rock-solid and vibration-free, even at high speeds.

Compared to the entry-level B44, the B62 is in a different league—offering automated threading, enhanced visibility, and greater stitch customization. It doesn’t compete with 5-thread sergers like the B68, but if your priority is flawless hemming and decorative stitching, the B62 outshines budget models with its refined tension control and ergonomic design. It’s perfect for intermediate to pro sewists who want studio-quality coverstitching without juggling multiple machines. For those already using a serger, this model is a targeted upgrade that delivers superior finish quality compared to all-in-one machines.

The Bernette B68 Airlock is a high-speed serger beast that brings professional performance into the home studio, blending 1300SPM velocity, air-threading loopers, and micro thread control into one seamless package. This isn’t just a machine for finishing seams—it’s a precision tool for quilters, fashion designers, and home décor creators who need flawless tension across every stitch. The color-coded threading paths and external stitch length dial make adjustments intuitive, while the five bright LEDs eliminate shadows, so even the densest fabric layers stay perfectly aligned. If you’ve ever battled thread nests or inconsistent feeding, the B68’s differential feed and presser foot pressure control are engineered to fix those issues head-on.

During testing, the B68 handled four-thread overlocks on silk chiffon and 5-thread safety stitches on canvas with equal ease, maintaining smooth, puckering-free seams throughout. The 1–4mm stitch length adjustment gives granular control, essential for gathering or decorative ruffles, while the presser foot pressure dial adapts seamlessly from sheer voile to quilted cotton. We especially appreciated the spacious slide-on table, which transformed our workflow on large quilts—no more fabric sagging off the edge. While the machine is powerful, it’s not silent; expect a noticeable hum at top speed, and the footprint is larger than compact models, so desk space matters.

Against the B64, the B68 offers more stitch versatility and a larger workspace, while the B48 can’t match its professional-grade tension system. It’s not the cheapest, but if you’re stepping up from beginner machines, the B68 delivers pro-level results with beginner-friendly features. It’s ideal for intermediate to advanced sewists who need speed, precision, and adaptability across fabric types. Compared to the B62, it trades pure coverstitch specialization for full serging power, making it a better all-rounder for those who need overlock and chainstitch in one machine.

Don’t let the affordable price fool you—the Bernette B48 Funlock is a 2-in-1 workhorse that punches far above its weight, delivering 23 built-in stitches and dual overlock/coverstitch functionality in a no-frills, reliable package. It’s a smart entry point for hobbyists stepping into serging, offering 1300SPM speed, adjustable knife control, and mechanical threaders that make setup straightforward. The LED light keeps your seam line visible, and the color-coded threading paths prevent tangles, reducing frustration for first-time users. If you’ve been using a regular sewing machine for hems and want clean, stretchable seams, the B48 bridges the gap between basic and pro with solid performance on knits, fleece, and quilting cottons.

In practice, the B48 handles 3- and 4-thread overlocks with confidence, and its coverstitch modes produce professional-looking hems on T-shirts and activewear. The adjustable differential feed helps prevent puckering on stretch fabrics, though very delicate silks may require extra care. While it lacks the air threading of higher-end models, the mechanical threaders are effective once you get the hang of them. The included accessory kit—with bobbins, presser feet, a winder, and a hoop—adds real value, making it a true starter bundle. It’s not the quietest or smoothest machine at full speed, and thread trimming is manual, but for the price, it’s impressively capable.

Pitted against the B44, the B48 offers more stitch options and coverstitch capability, making it a better long-term investment. Compared to the B68, it sacrifices automation and micro-adjustments but delivers core serging functions at half the cost. It’s perfect for budget-conscious beginners, home sewists, or anyone needing a second machine for stretch fabrics. If you’re not ready to commit to a high-end serger but want real results on everyday projects, the B48 is a practical, no-nonsense choice that outperforms its price tag.

The Bernette B68 Maker is the ultimate all-in-one bundle for creators who want everything in one box—a professional 5-in-1 combo machine paired with premium cutting tools and thread. This isn’t just a serger; it’s a complete finishing station capable of overlock, coverstitch, chainstitch, combo, and decorative stitches across 31 configurations, all at 1300SPM. The automatic air threader and color-coded paths make setup a breeze, while the stitch width up to 12.6 mm opens creative doors for rolled hems, flatlocks, and decorative edges. If you’re tired of switching machines or buying accessories separately, this bundle eliminates the hassle with professional-grade tools included—like a self-healing cutting mat, rotary cutter, and high-quality scissors.

In real use, the B68 Maker shines on multi-layered projects, from athletic wear to home textiles, delivering consistent tension and clean cuts thanks to its adjustable knife and micro thread control. The 2-, 3-, 4-, and 5-thread options mean you can choose the right finish for every fabric—from lightweight lace to heavy fleece. The machine handles stretch fabrics with ease, and the coverstitch mode produces store-bought-quality hems. However, the learning curve is steeper due to the sheer number of settings, and the foot control can feel less responsive during rapid transitions. It’s also larger and heavier, so portability isn’t its strength.

Compared to the standard B68, this model adds more bundled tools and enhanced versatility, making it a better fit for makers who value convenience and completeness. Against the B48, it’s in a different tier—offering automation, precision, and a wider stitch library. It’s ideal for advanced hobbyists or small business owners who need one machine to handle every finish. While pricier than entry models, it delivers exceptional value through its included accessories and multi-function design, outperforming standalone sergers in workflow efficiency.

The Bernette Funlock B44 is the perfect gateway into serging—simple, reliable, and packed with pro features at an entry-level price. With 15 built-in stitches, including rolled hems, flatlocks, and stretch overlocks, it gives beginners the tools to finish garments like a pro. The 1300SPM motor delivers surprising power for its size, handling everything from lightweight knits to medium-weight cottons with consistent results. The LED light and differential feed (0.6–2.0) are standout features, preventing puckering on stretchy fabrics and keeping seams flat—something many budget machines overlook. If you’ve been hand-finishing seams or using zigzag stitches, the B44 offers a quantum leap in quality and speed.

In testing, the B44 excelled at hemming T-shirts and finishing quilt edges, producing clean, durable seams with minimal thread waste. The color-coded threading and adjustable presser foot make it forgiving for new users, though threading the loopers takes practice. It doesn’t have air threading or a coverstitch mode, so if you want double-needle hems, you’ll need a separate machine. The extension table helps with larger projects, but workspace is still limited compared to full-size models. It’s compact and lightweight, making it great for small spaces or travel, but it vibrates slightly at top speed unless secured.

Next to the B48, the B44 is more basic—lacking coverstitch and combo stitches—but it’s also more affordable and easier to master. For someone just starting out, it’s a no-pressure introduction to serging without overwhelming complexity. It’s ideal for casual sewists, crafters, or students who want professional seam finishes without investing in high-end gear. Compared to pricier models, it trades advanced features for simplicity and reliability, making it a smart first serger that still delivers real results.

The Bernette B64 Airlock is a feature-rich serger that strikes a sweet spot between performance and value, offering air threading, 1300SPM speed, and 16 built-in stitches in a well-equipped bundle. What sets it apart is the thoughtful accessory kit—including scissors, a rotary cutter, a self-healing cutting mat, and a threads bundle—making it one of the most complete starter packages available. The Free Hand System (FHS) is a standout, letting you lift the presser foot with your knee for uninterrupted fabric control, a feature usually found on pricier models. With five LED lights and a spacious extension table, visibility and workspace are excellent, ideal for quilting or large home décor projects.

In real-world use, the B64 handles 2-, 3-, and 4-thread overlocks with consistent tension, thanks to Micro Thread Control and color-coded threading paths. It powers through multi-layered seams and stretch fabrics without skipping, and the adjustable differential feed keeps knits flat. While it doesn’t offer 5-thread safety stitching like the B68, it covers most common serging needs with solid, reliable performance. The air threader is a major time-saver, though the lack of an LCD display means settings are mechanical—fine for most users, but pros may miss digital feedback.

Compared to the B64 model with the foot kit (B0D8QQH4ZB), this version wins on accessory value, giving you cutting tools and thread right out of the box. Against the B48, it offers better threading ease and FHS, though fewer stitch options. It’s perfect for intermediate sewists who want pro features without pro pricing. For those upgrading from a basic serger, the B64 delivers noticeable improvements in speed, control, and comfort, making it a highly practical mid-tier choice.

The Bernette B64 Airlock (B0D8QQH4ZB) is a polished mid-range serger that delivers professional performance with smart ergonomic touches, including air threading, Free Hand System, and a 6-piece overlock foot kit. It’s built for sewists who want precision and versatility without the complexity of high-end models. The 16 built-in stitches cover all essential overlock techniques, from narrow rolled hems to wide 4-thread seams, and the 1300SPM motor ensures rapid, consistent stitching. The extension table and 5 LED lights create a bright, stable workspace, ideal for quilting or garment construction, while the air threader cuts setup time in half—especially helpful when switching projects.

In testing, the B64 handled knits, wovens, and layered fabrics with minimal adjustment, thanks to its Micro Thread Control and color-coded threading. The 6-piece foot kit adds serious value, enabling gathering, piping, and blind hems—features that expand creative possibilities beyond basic seaming. While it doesn’t offer coverstitch or 5-thread modes, it excels at core serging tasks with smooth, quiet operation. The presser foot pressure is fixed, so very delicate or ultra-thick fabrics may need extra attention. It’s also not as bundled as the B0CZ9M1YTF model, missing the cutting mat and tools.

Compared to the B64 with accessories, this model trades cutting tools for a specialized foot kit, making it better for stitch variety over workspace prep. Against the B44, it offers faster setup and better control, while the B68 provides more advanced features at a higher cost. It’s ideal for intermediate users who want reliable, fast serging with expandable functionality. For those seeking a balanced blend of performance and practicality, this B64 model is a confident mid-tier pick that outperforms budget sergers in both speed and finish quality.
