Key Features
Cast Iron Construction
Heavy-duty cast iron body provides stability, reduces vibration, and ensures decades of reliable operation. The weight prevents "walking" during high-speed sewing.
Oscillating Hook System
Singer's patented oscillating hook creates reliable lockstitch formation with perfect tension balance between needle and bobbin threads.
Drop Feed Mechanism
Allows for darning, embroidery, and button sewing by lowering the feed dogs. Essential for free-motion sewing techniques.
Reverse Stitching
Built-in reverse function for securing seam beginnings and ends. Some models feature a simple lever, others have push-button control.
Adjustable Presser Foot Pressure
Spring-loaded mechanism allows adjustment for different fabric thicknesses, from delicate silks to heavy denim.
Built-in Light
Early electric models feature an integrated sewing light with bulb replacement access. Some use unique screw-base bulbs.
