Tech Supply Shed stocks Brother overlocker machines for NZ sewers. An overlocker (also known as a serger) trims, wraps, and stitches fabric edges simultaneously for a clean, professional finish on garments and soft furnishings - the same finish you see on store-bought clothing.

4-Thread Overlockers

Professional Seams at Home

4-thread overlockers deliver fast, reliable overlocking for garment construction and finishing. With differential feed to prevent fabric stretching or puckering, they handle everything from fine jersey to heavier woven fabrics with ease.

Why Use an Overlocker?

Overlockers work significantly faster than standard sewing machines for seam finishing, and the result is stronger and more professional. Ideal for dressmaking, activewear, and any project where raw edges need to be neatly enclosed.

How to Choose an Overlocker

Thread Count

Most home overlockers use 3 or 4 threads. A 4-thread overlocker produces a stronger, more durable seam - better for garments that will be washed frequently or worn under stress. 3-thread is lighter and suitable for decorative edges and rolled hems.

Differential Feed

Differential feed adjusts the ratio between the front and rear feed dogs - preventing stretchy fabrics from stretching out or puckering during overlocking. Essential for jersey, knit, and activewear fabrics common in NZ home sewing.
