10 Best Overlock Machine 2025 in the United States

The SINGER X5004-HD Metal Frame Serger & Overlock Machine is a robust and versatile tool designed for both novice and experienced sewers. It boasts a heavy-duty metal frame that ensures durability and stability, making it well-suited for handling thicker fabrics like denim and upholstery with ease. This sturdiness helps in reducing vibrations, leading to skip-free and precise stitching, which is essential for achieving professional-quality results. The machine offers a flexible stitching experience with its 2-3-4 thread capability and eight built-in stitch options, which can cater to a variety of sewing projects, from basic seams to decorative edges.

This versatility is further enhanced by the adjustable differential feed, which prevents puckering on lightweight fabrics and offers smooth fabric handling on stretchy materials. At a high-speed performance of 1,300 stitches per minute, it allows for quick completion of large projects, a significant advantage for those working on time-sensitive tasks. Ease of use is a strong point, highlighted by the inclusion of a comprehensive accessory kit that neatly stores all necessary tools within the machine’s built-in compartment.

However, despite these strengths, the machine may present a learning curve for beginners due to its various adjustable settings and threading process. Additionally, while the larger cutting knife is great for heavy-duty materials, it might be overkill for those who primarily work with lighter fabrics. The lack of a battery option limits its portability, confining its use to areas with electrical outlets. The SINGER X5004-HD is an excellent choice for users looking for a durable and high-performing serger that can handle a range of fabrics and projects, provided they are comfortable with its advanced features and settings.

The Brother AIR1800 Air Serger stands out with its innovative Jet Air Threading, which makes threading the machine incredibly easy and quick by blowing the thread through the looper at the press of a button. This feature can be particularly helpful for those who frequently change thread colors. With the ability to use 2, 3, or 4 threads, and various stitch options like flatlock, overlock, and rolled hem, it offers versatility for different sewing projects. The color-coded thread guides help keep everything organized and user-friendly, which is great for both beginners and experienced users alike.

The machine performs exceptionally well on challenging materials such as fine knits and stretchy fabrics, providing professional-quality finishes that would be difficult to achieve with a standard sewing machine. The LED-lit work area ensures good visibility, especially useful when working with dark fabrics. However, there are a few downsides to consider. The machine is somewhat bulky, weighing 21.5 pounds and having dimensions that may require significant workspace. Additionally, it is designed to operate only on 120 volts, limiting its use to the US unless a voltage converter is used, which could affect the warranty.

With a 1-year limited warranty, it is a reliable choice for those in the market for a high-quality serger. Potential buyers should be aware of its size and voltage limitations before making a purchase.

The Brother Coverstitch Serger 2340CV is a solid choice for sewing enthusiasts looking for a dedicated cover stitch machine. One of its notable strengths is its sturdy metal frame, which enhances durability and stability during operation. With a maximum sewing speed of 1,100 stitches per minute, this machine allows for efficient sewing, making it ideal for those who want to complete projects quickly, especially when working with stretch fabrics for necklines and hems.

This machine offers versatile stitch options, including tri-cover stitches and the ability to adjust stitch width from 3mm to 6mm. The differential feed feature is also beneficial for handling various fabric types, ensuring a smooth and even finish. The color-coded threading system simplifies setup, making it accessible even for beginners who might feel intimidated by threading complexities.

There are a few drawbacks to consider. As a cover stitch machine, the 2340CV is not as versatile as some other overlock machines that can perform additional functions like overlocking or serging. Users looking for a multipurpose machine might find this limiting. Additionally, it is specifically designed for 120-volt use in the US, which might not suit users outside this region. While it comes with some essential accessories, including snap-on presser feet, the selection may be limited compared to other models that come with a broader range of attachments.
