If you sew knits, activewear, or anything that needs a flat, stretchy, ready-to-wear finish, a coverstitch machine changes everything. Unlike a twin needle on a regular sewing machine, a dedicated coverstitch produces the same durable, professional hem you see on store-bought T-shirts, leggings, and swimwear — flat, stretchy, and built to survive the wash.
These machines use one or more needles paired with a looper thread to lock stitches on both the top and bottom of the fabric, giving hems the stretch and strength that garments made from jersey, ponte, or spandex demand. Whether you’re a beginner looking for an affordable entry point or a serious garment sewist who wants industrial-style speed and control, there’s a coverstitch machine suited to your budget and skill level.
Below, we count down five of the best coverstitch machines available, from a solid budget option to a feature-packed, high-speed model built for serious knit sewing.
5. Janome CoverPro 2000CPX Coverstitch Machine
The Janome CoverPro 2000CPX sits at the top of Janome’s dedicated coverstitch lineup, and it shows. It blends the speed of an industrial cover hem machine with the layout and ease of a home sewing machine, running at up to 1,000 stitches per minute. The 2000CPX offers three stitch configurations: a 1-needle, 2-thread chain stitch for seaming; a 2-needle, 3-thread cover stitch for classic hems; and a 3-needle, 4-thread triple cover stitch for decorative, heavy-duty finishes on stretch fabrics. Stitch length adjusts from 1–4mm, and differential feed ranges from 0.5 to 2.25, so it handles everything from lightweight jersey to dense ponte without stretching or puckering.
What sets this model apart is its exclusive free arm and extra-large 4″ x 5.5″ bed space, letting you slide a sleeve, cuff, or pant leg directly onto the arm for a seamless hem. It also includes Tension Level Control (TLC) to prevent puckering on delicate fabrics and Janome’s Seam Tightening System (STS), a spring-based mechanism that keeps looper thread tension consistent for tighter, flatter stitches. Color-coded threading, a built-in stitch reference chart, and bright LED lighting round out a machine designed for sewists who are serious about knitwear.
4. Janome CoverPro 1000CPX Coverstitch Machine
The Janome CoverPro 1000CPX is the mid-tier sibling to the 2000CPX, offering nearly the same industrial-grade performance at a more accessible price point. It’s built as a high-speed, long-arm, heavy-duty cover hem machine that sews up to 1,000 stitches per minute, with the same extra-large 4″ x 5.5″ bed space and free arm design for tackling sleeves, cuffs, and other tight areas without opening a seam.
This model offers two stitch configurations rather than three: a 1-needle, 2-thread chain stitch and a 2-needle, 3-thread cover stitch, covering the two most commonly used coverstitch functions for hemming knitwear and activewear. Stitch length runs 1–4mm and differential feed adjusts from 0.5 to 2.25, giving reliable control across jersey, spandex, and french terry. It also includes Janome’s Seam Tightening System (STS), which uses a spring rather than a tension dial to reduce slack in the looper thread for tighter, flatter results.
A printed Quick Reference Chart lets you dial in settings without consulting the manual, and color-coded thread guides keep setup approachable even for newer sewists. It ships with three spools of white serger thread pre-threaded on the machine, so you can start sewing test seams right out of the box. For sewists who want Janome’s signature coverstitch quality without paying for the 2000CPX’s extra triple-needle function, the 1000CPX is a strong middle-ground choice.
3. Bernette B48 Funlock Serger Coverstitch Machine
The Bernette B48 Funlock takes a different approach from the dedicated Janome and Brother models on this list: it’s a true 2-in-1 combo machine, merging a full overlocker with a coverstitch machine in one unit. It offers 23 built-in stitches in total — 15 overlock stitches, 3 coverstitches, 4 combo stitches, and 1 chain stitch — running at speeds up to 1,300 stitches per minute, the fastest of any machine on this list.
Stitch widths are generous: overlock stitches go up to 7mm, coverstitches come in 2.8mm or 5.6mm widths, and combo stitches stretch up to 10mm, with a 1.5mm rolled hem option for delicate finishes. The lower looper and chain looper both include mechanical threaders, and color-coded thread paths make switching between overlock and coverstitch functions more manageable than you’d expect from a combo machine. A knife operated from below ensures clean cut edges and safer handling, and a bright LED light keeps the stitching area visible.
Because it does the job of two machines, the B48 is a smart pick for sewists with limited space or budget who don’t want to own separate serger and coverstitch units. The tradeoff is a steeper learning curve when converting between stitch types, but for versatility per dollar, it’s hard to beat.
2. Janome CoverPro 900CPX Coverstitch Machine
The Janome CoverPro 900CPX is the most budget-friendly machine in Janome’s dedicated coverstitch line, built for sewists who want the CoverPro name and reliability without paying for the extra bells and whistles found on the 1000CPX or 2000CPX. Like its siblings, it’s designed as a high-speed, long-arm, heavy-duty cover hem machine that looks and handles much like a standard home sewing machine.
It features an extra-wide bed space and the same free arm capability that makes finishing sleeves, cuffs, and necklines far easier than on a flatbed-only machine. You can choose between a 1-needle, 2-thread chain stitch or a 2-needle, 3-thread cover stitch, covering the essentials most home sewists need for hemming knit garments. Janome’s Seam Tightening System (STS) is included here too, reducing slack in the looper thread for tighter, flatter stitches regardless of fabric weight. A printed Quick Reference Chart on the front of the machine helps with stitch and tension settings without flipping through a manual.
Real-world users note the 900CPX is heavy-duty and reasonably easy to thread, though it lacks a speed-limiting control, meaning the foot pedal runs closer to all-or-nothing. Still, for sewists testing the coverstitch waters or working with a tighter budget, it delivers dependable, wash-resistant hems.
1. Brother 2340CV Coverstitch Machine
Taking the top spot is the Brother 2340CV, widely regarded as one of the best entry points into coverstitching thanks to its combination of solid performance and accessible price. This dedicated cover-stitch-only serger uses three needles and one looper thread to produce a 2/3/4-thread cover stitch, along with a wide and narrow cover stitch ranging from 3mm to 6mm, plus a tri-cover stitch and chain stitching option. Maximum sewing speed reaches 1,100 stitches per minute, and differential feed adjusts from 0.7 to 2.0 to prevent wavy or stretched stitching on knits and stretch fabrics.
The 2340CV is built with a sturdy metal frame and internal parts, and it comes with easy, lay-in threading, color-coded thread guides, and snap-on presser feet, making it approachable for sewists who haven’t used a coverstitch machine before. Stitch length adjusts from 2mm to 4mm, and it includes presser foot pressure adjustment for handling different fabric thicknesses. It’s backed by a 25-year limited warranty covering the chassis, with shorter terms on electronic components and labor.
Reviewers consistently point to its budget-friendly price, balanced tension, and beginner-friendly controls as standout strengths, while noting the lack of an automatic thread cutter and a relatively small work area as its main limitations. For sewists who want reliable coverstitch results — hemming T-shirts, attaching binding, or topstitching necklines — without a big investment, the Brother 2340CV earns its place as the top overall pick.
Conclusion
Choosing the right coverstitch machine comes down to how often you sew knits, how much workspace and budget you have, and whether you want a dedicated machine or a combo unit. The Brother 2340CV is our top pick overall for its balance of affordability and dependable performance, making it ideal for sewists just getting into coverstitching. If you want more speed and stitch versatility, the Janome CoverPro 900CPX, 1000CPX, and 2000CPX offer a clear upgrade path, with the 2000CPX delivering the most advanced features like Tension Level Control and a triple-needle cover stitch. Meanwhile, the Bernette B48 Funlock is the machine to consider if you want overlock and coverstitch functions combined into a single, space-saving tool.
Whichever model you choose, a coverstitch machine is an investment that pays off in cleaner hems, sturdier seams, and garments that look and perform like professionally finished pieces. Match the machine to your sewing habits, and you’ll be turning out polished knitwear in no time.
