Janome MyLock 644D Overlocker


Essential for creative overlocking techniques

The MyLock 644D is one of the most advanced Janome overlockers with speeds up to 1300 stitches per minute. It features electronic control, a handy needle threader, and an easy upper knife release. An instructional DVD ensures that you'll be overlocking with professional results in no time.

The MyLock 644D has 2 needles and 2, 3 or 4 thread stitching capabilities. Equipped with differential feed, which is adjustable from .05 to 2.25, the MyLock 644D provides increased control for handling all types of fabrics and is essential for creative overlocking techniques. And, you can adjust the cutting width of the knives up to 7.3mm, wider than any other MyLock overlocker.

Threading is simplified by colour-coded thread guides and a self-threading lower looper. Simply lay the thread into the guide, flip a switch, and the lower looper is threaded, the MyLock 644D is one of the lowest priced overlockers to have this feature. The guide is automatically returned to its normal position when you turn the balance wheel. And when you lift the presser foot for rethreading, the thread tensions are automatically released so you can draw the thread smoothly. Because a lower looper pre-tension control eliminates the need to change tension for rolled hems, you can switch quickly to rolled hemming without changing the needle plate.

Easy rolled hem change over

No need to change the needle plate for rolled hemming. Just slide the needle plate setting knob to the "R" position to switch the chaining finger to the rolled hemming position.

2 thread overlocking

Set your overlocker for 2 thread use by sliding thread guide from 3 or 4 thread position to 2 thread position and attach spreader to right looper.

Lower looper threading

By rotating the threading lever, the lower looper thread guides will be accessible, making threading easy. Turn the balance wheel and the threading lever will return to its original position.

Retractable knife

The upper knife can be quickly and easily deactivated when not required.

Adjustable cutting width

Easily adjust the cutting width to suit the thickness of the material. An easy way for correcting the seam tension.

Thread cutter

The thread cutter is conveniently located on the side of the machine and trims the thread neatly and easily.

Tension release

Lifting the presser foot automatically releases the tensions which allows you to easily draw the threads
through when threading, just like a sewing machine.

Customer testimonials

I bought a Janome/SMD 664D overlocker. I have no experience with overlockers but the machine is easy to use and has a relatively simple threading system with clear instructions on the accompanying DVD and pictorially adjacent to the lower loopers on the machine itself. I also have a Janome/SMD 3000 bought several months ago from Sewing Machines Direct. Both machines were well priced, appear well made and sew beautifully, and arrived in good condition thanks to good packaging.

P.B. Ireland (18th January 2017)

I called up and spoke to Russell on the phone asking for advice on buying an Overlocker. He had several in a Black Friday sale, and as I had no chance of testing or trialling any of them (we live too far away from his shop) he gave me sound advice over the phone. For my needs, he suggested the Janome SMD644D. It arrived next day as promised, and is fantastic so far! The service he provides over the phone to the next day delivery, and free extras you receive, I couldn't be happier.

S.B. Cornwall (1st December 2016)

Brought the Janome Overlocker, as we already have a Janome sewing machine, for my partner. She is extremely happy with the ease of use and the build quality looks up to Janomes normal high standards. Sewing machines direct offered a quick and free delivery with a price promise. First class service.
