The 74066 is a specific finishing tool for photo-etched parts. The diamond working surface and half-circle shape are the reasons to compare it with a general model file: the seller describes that shape for hard-to-reach areas rather than simply naming a longer file.
If the task is a metal detail in a restricted area, compare its contact shape with the 74126 half-round hard-chrome file. The Mudder set provides several diamond-coated profile types when the need is a choice of round, flat or triangular forms across a miniature. None of those descriptions supplies a shared grit or tooth-density scale that would make the tools numerically equivalent.
This reference is one model 74066 file. The diamond working-section length is not separately specified, so confirm that dimension if the file must reach deeply into a recess.

Your questions about this product
Why choose this over a general plastic file?
It is specifically described for photo-etched metal parts and has a half-circle diamond working form for difficult access.
How does it differ from the 74126?
The 74126 is described as a 5 mm half-round hard-chrome file for plastic and metal work. This 74066 is the dedicated diamond/photo-etch option.
Can I compare its grit directly with a sanding sponge?
No numeric grit is supplied. Compare shape, working surface and target task rather than assigning a sanding equivalent.
A dot-matrix glass filing face and resin grip provide a reusable rigid option for plastic-model nubs and parting lines.
