The Brother 2340CV is a dedicated coverstitch machine for hems, necklines and decorative seam finishes. Its wide, narrow and tri-cover stitch options suit stretch fabrics, but it does not take the place of a standard overlock serger for trimming and finishing raw edges.
Choose it if you want coverstitched hems on knits or a decorative finish on garments. If your main need is seam construction and edge finishing, compare a regular serger instead.
What does the Brother 2340CV do?
The Brother 2340CV makes cover stitches, including wide, narrow and tri-cover options. Brother also describes it as suitable for stretch fabric, necklines and hems.

Pros
- Made for cover stitching
- Offers wide, narrow and tri-cover stitch options

A coverstitch is useful for garment hems where you want parallel top stitching and a looped underside. It can also create decorative finishes, but the machine's dedicated role matters: it isn't a general-purpose overlocker.
If you are still comparing machine types, our guide to the best coverstitch sewing machine options can help you weigh dedicated coverstitch choices against your sewing plans.
How do the stitch options fit common projects?
The 2340CV's wide, narrow and tri-cover stitch options give you choices for hems and decorative seam finishes. The stated coverstitch capability spans 3 to 6 mm for thicker materials.
| Detail | Brother 2340CV |
|---|---|
| Machine type | Dedicated coverstitch serger |
| Stitch options | Wide, narrow and tri-cover stitch |
| Cover stitch capability | 3–6 mm |
| Maximum sewing speed | Up to 1,100 stitches per minute |
| Differential feed | 0.7–2.0 |
| Included feet | Standard foot and hem sewing presser foot |
| Power | 120 volts |
Use the wide or narrow option to suit the look you want, and check the manual for setup details. The tri-cover option gives another finish choice when you want more visible parallel stitching.
The available details don't mean every stitch is suited to every fabric weight. Test the chosen stitch and differential feed setting on a scrap of the same fabric before sewing the garment.
Is the 2340CV easy to thread?
The 2340CV has color-coded guides, lay-in threading and a fast thread looper system to support threading. These features can make setup more approachable, though a dedicated coverstitch machine still takes practice.
Thread path and needle placement affect the stitch. Follow the Brother manual carefully when changing thread or needles, and keep a sample from each successful setup so you can repeat it.
The included hem sewing presser foot is relevant for hemming work. The standard foot gives you another included foot for general coverstitch use.
What are the limits of this Brother coverstitch serger?
The main limit is that the 2340CV is dedicated to cover stitching, rather than standard overlock work. It is not the right single machine if you need to trim and finish raw edges as you sew.
A standard serger uses overlock stitches to secure fabric edges and seams. The Brother 1034D Serger Overlock Sewing Machine is an example of a different machine type, with 3- and 4-thread overlock options.
A coverstitch can finish a hem, but it doesn't perform every task involved in constructing a garment. If you want a plain sewing machine to handle seams and quilting too, read Can You Quilt with a Serger Instead of a Sewing Machine? before deciding whether a serger should be your main machine.
Who should consider the Brother 2340CV?
The 2340CV suits sewists who regularly finish stretch-fabric hems, necklines or decorative seams and want a machine dedicated to that job. It may be a good fit if you already have a regular sewing machine or overlocker for other tasks.
It is less suitable as a first and only machine if you want one tool for seams, edge finishing and coverstitched hems. Think through the finishes you use most, then decide whether a separate coverstitch machine earns its space.
If you also need general-purpose sewing, compare the Janome HD3000 sewing machine.
The machine is described for US 120-volt use. If your sewing room uses another voltage, check compatibility with Brother before buying, since other use or sale voids the warranty.
How does it compare with Brother overlock sergers?
The 2340CV is the choice for coverstitched hems, while Brother's 1034D and ST4031HD are overlock sergers. The right pick depends on whether your priority is garment finishing, raw-edge control or heavier fabric handling.
| Machine | Main role | Notable features |
|---|---|---|
| Brother 2340CV | Coverstitch | Wide, narrow and tri-cover stitches; hem foot included |
| Brother 1034D | Overlock serger | 3- or 4-thread stitching; standard, gathering and blind stitch feet |
| Brother ST4031HD | Heavy-duty overlock serger | 3- or 4-thread stitching; carbon steel blade and large extension table |
The 1034D is a more direct match for overlocking seams and edges. The ST4031HD adds a high-durability blade and extension table for projects involving heavier fabrics.
Neither overlock alternative provides the 2340CV's stated coverstitch functions. Some sewists may want both kinds of machine if their projects call for both secure edges and coverstitched hems.
Is this machine useful for quilting?
The 2340CV is intended for coverstitched finishes, not as a quilting machine. It could help finish a knit garment or decorative seam, but quilting calls for different seam and construction tasks.
Before adapting a serger to quilting, consider the stitch type, fabric handling and project. Our guide to Can You Use a Serger to Quilt? explains where a serger may fit and where a conventional sewing machine is more practical.
What should you check before buying?
Check that you want coverstitching specifically, have room for a dedicated machine and can use a 120-volt appliance. Those points help prevent buying a machine whose main function doesn't match your regular projects.
Confirm which hems and finishes you expect to make, then review the manual's threading and stitch setup steps. The included hem foot is useful context, but it doesn't replace checking that the machine supports the fabric and finish you plan to sew.
Brother specifies a 25-year limited warranty. Read the current warranty terms and confirm local support before purchase, especially if the machine will be used outside the US.
Is the Brother 2340CV worth choosing?
The Brother 2340CV is worth considering when coverstitched hems are a regular need and you already have another machine for overlocking or general sewing. Its stitch range, threading guides and included hem foot all point to garment finishing.
Choose the 2340CV for coverstitching, the 1034D for standard overlock work, and the ST4031HD if heavier fabric overlocking is the priority. If you need to decide whether a dedicated model belongs in your setup, start with the coverstitch machine comparison.
