Problem: The original handwheel on the Singer Heavy Duty 4423 is small, difficult to crank, especially with thick materials like leather. This can lead to wrist fatigue and hinder precise control, impacting your sewing enjoyment.
Solution: This larger diameter (165mm) handwheel upgrade provides improved grip and leverage, making it easier to turn and significantly reducing wrist strain. It fits perfectly onto your Singer Heavy Duty 4423 without wobbling or slipping, ensuring smooth and effortless sewing. Say goodbye to hand cramps and hello to effortless control, even when working with multiple layers.
