# Janome overlockers compared Source: https://stitchandhem.co.uk/best/janome-overlockers-compared Publisher: Stitch and Hem. Picks are based on what the Amazon listings state, not on hands-on testing. Method: https://stitchandhem.co.uk/how-we-pick Janome's overlockers range from simple 3 and 4 thread machines to models with 2 thread stitches and air threading. All of them trim and finish seams in one pass, so the differences lie elsewhere. Threading is the big one: the lower looper is the fiddly part, and Janome's lay-in and air threading systems exist to make it easier. Next comes the number of threads. A 2 thread option gives lighter finishes and flatlock, while 3 and 4 thread are the everyday seams. Differential feed stops knits stretching and fine fabrics puckering, and an easy rolled hem change matters if you sew scarves or napkins. This guide compares six Janome overlockers in the current collection: the AirThread 2000D, MyLock 654D, 9300DX, 8002D, 8004D and MyLock 454D. Each is judged by thread options, differential feed, rolled hem, threading system and weight, using only what the listings state. ## Products ### 1. Janome 8004D Threads: 3 or 4; Differential feed: Adjustable; Rolled hem: Yes, plus flatlock; Threading aid: Colour coded guides, pre-threaded; Weight: 7.66 kg A three or four thread Janome overlocker that arrives pre-threaded from the factory, with colour coded guides, adjustable differential feed, cutting width and tension, rolled hems and flatlock seams. In its favour: - Pre-threaded from the factory, so you can sew a first seam straight out of the box. - Adjustable differential feed, cutting width and tension are all listed. - Rolled hems and decorative flatlock seams are both stated. Good to know: - There is no lower looper threading aid in the listing beyond colour coding. - Top speed and included feet are not given in the listing. ### 2. Janome AirThread 2000D Threads: 2, 3 and 4; Differential feed: Not stated; Rolled hem: Not stated; Threading: One push air threading, lay-in; Weight: 7.89 kg Janome's air threading overlocker, with one push air threading for the loopers, lay-in needle threading, a built-in one step converter, an 8 piece feed dog system and 2, 3 and 4 thread stitches. In its favour: - One push air threading takes the hardest step, looper threading, out of setup. - A built-in one step converter is listed, so the 2 thread stitches need no separate part. - An 8 piece feed dog system and adjustable foot pressure are stated.
