Why Do Embroidery Needles Keep Breaking?

Breaking embroidery needles is a common problem in embroidery and is often caused by machine alignment issues rather than the needle itself.

Inside an embroidery machine, a small metal tab sits in a notch on the hook assembly. This tab prevents the hook slot from rotating and ensures embroidery needles enter the correct opening on every stitch. If the slot moves out of position, the needle can strike metal instead of passing through cleanly, which can cause embroidery needles to break.

To check this, remove the bobbin case and needle plate so the hook area is visible. Slowly turn the machine by hand and watch how the embroidery needle enters the hook. The slot should remain centred with the needle path. If it has shifted, loosen the retainer tab and reposition it so embroidery needles pass through cleanly. The gap between the tab and the notch should be roughly the thickness of a needle to allow the thread to move freely.

Other common causes of embroidery needle breakage include using the wrong embroidery needle size, incorrect thread tension, poor thread quality, loose hooping, or insufficient stabiliser. Running embroidery machines at high speeds on dense designs can also increase stress on embroidery needles.

Keeping your embroidery machine correctly aligned and choosing the right embroidery needles for each job will help reduce breakages and improve stitch quality.
