Brother ST4031HDBR 3-4 Thread Serger Sewing Machine

Strong & Tough serger for multi-thread finishing

The Brother ST4031HDBR is a 3-4 thread serger built for sewers who need professional edge finishing on woven and knit fabrics. Two needles and selectable thread counts let you switch between overlock, narrow hem, rolled hem and ribbon lock stitches. Color-coded threading guides reduce setup time for home studio users.

Fits a standard sewing table and runs on mains power

The machine sits on a flat work surface and connects to a household outlet. Differential fabric feed keeps layers aligned without manual stretching, freeing you from constant tension tweaks. Presser foot pressure and stitch width adjust from 3.00mm to 7.00mm via external dials, so you can match heavy denim or light chiffon without changing plates.

Handles up to 1300 stitches per minute on four

Four-thread overlock seams finish garment edges quickly, while three-thread settings cover lighter tasks. The 2-point tension device balances each needle independently, giving clean results on stretch fabrics. Heavy layered projects or decorative chain stitching beyond the listed stitch types will need a separate coverstitch or embroidery machine.
