JUKI MO-644D — 2/3/4-Thread Household Overlock with Differential Feed & Dial Tension

The JUKI MO-644D is a dependable and easy-to-use household serger designed for both beginners and experienced sewists who want clean, professional overlock finishes at an accessible price point. Featuring 2-, 3-, and 4-thread stitch capability, built-in differential feed, a strong knife system, and intuitive controls, the MO-644D delivers smooth, accurate results on a wide range of fabrics — from lightweight knits to heavier materials. Ideal for garment construction, activewear, stretch fabrics, and home sewing projects.


What Sets the MO-644D Apart

Color-Coded Threading Guides

Threading is quick and stress-free thanks to clearly marked, color-coded thread paths that guide you step by step through correct setup.

Easy Tension Adjustment

1-rotation tension dials with highlighted “normal” ranges allow fast, precise tension balancing for stable, consistent stitches at any sewing speed.

Multi-Function Presser Foot

The standard multipurpose presser foot supports overlock stitching as well as the insertion of elastic, tape, ribbon, or sequins. Snap-on design makes it easy to switch to optional JUKI specialty feet and expand creative possibilities.

Heavy-Duty Knife System

A dedicated knife drive ensures smooth, reliable cutting across both lightweight and heavier fabrics, producing clean edges and professional finishes.

Precision Seam Guide

Built-in seam guide markings on the guard cover help maintain accurate seam allowances, improving consistency and stitch quality.

Bright Sewing Area Lighting

Well-positioned lighting illuminates the needle and fabric area for improved visibility during detailed work.

Adjustable Cutting Width

The lower knife cutting width can be easily adjusted via dial, allowing fine control for standard overlocking or narrow edges.

Differential Feed

Ensures even fabric feeding by preventing stretching or puckering on knits and lightweight materials. Also enables decorative techniques such as lettuce-edge finishes.

Easy Stitch Length Adjustment

Convenient stitch-length dial allows quick fine-tuning for specialty threads, decorative seams, or different fabric weights.


How It Improves Your Workflow

  • Beginner-Friendly Setup & Operation
    Color-coded threading, intuitive tension dials, and snap-on feet make the MO-644D easy to learn while still supporting advanced sewing techniques.

  • Clean, Reliable Results
    Balanced tension, differential feed, and consistent cutting deliver smooth, professional-quality seams on a wide range of materials.

  • Versatile for Everyday Sewing
    Perfect for garments, sportswear, knit fabrics, children’s clothing, decorative edges, and basic home décor projects.

  • Compact, Durable, and Affordable
    A compact footprint combined with JUKI’s proven durability makes the MO-644D an excellent entry point into high-quality overlocking.
