Main Features & Creative Benefits

Heavy Duty Core & Oversized Cutting System

Constructed around a rigid, all-metal inner frame, the SINGER HD0400S eliminates high-speed vibrations for highly stable, skip-free overlocking. The machine's upper cutting blade is 60% larger than conventional overlocking knives, enabling it to slice smoothly through multiple layers of heavy denim and thick drapery materials.

Intuitive Color-Coded Threading System

Simplify your setup with color-coded paths clearly mapped out on the machine's internal access door. Easily reference the color-coded threading diagrams directly on the chassis to quickly navigate each thread down to its respective loopers and needle eyes, making start-up and maintenance incredibly smooth.

Adjustable Differential Feed & Rolled Hems

Control fabric feed ratios perfectly with the adjustable differential feed knob. Keep lightweight knits, stretchy spandex, and bias cuts completely flat without wavy distortions, or gather fabrics smoothly for ruffles. Plus, the built-in rolled hem lever lets you transition instantly from standard seams to rolled edges without swapping needle plates.
