66K, or L-style bobbins, are slightly narrower (~9mm) and are necessary for some machines, but can also be used in 15K (A-style bobbin) machines with a washer.
Plastic 66K spools are also bevelled. 15K (A-style) bobbins are slightly wider (~10mm) but are the most commonly used bobbin style in the UK.
Both styles can be used in domestic machines as well as some commercial embroidery machines.
To know which bobbin you require please refer to your sewing machine manual.
