Every figure below is a manufacturer specification read off the listing itself. The judgments are ours.

What the specification says

An 8 mm (0.31 in) straight shank, a cutter about 60 mm (2.36 in) long, four flutes, carbide. The manufacturer describes slot milling and drilling in stainless, carbon steel, cast iron, die steel, alloy steel and tool steel, on lathes and in machine shops. Part number AUNMAS43v7th1rk0-12. No EAN.

The shank is not a detail

Six millimeter, eight millimeter, quarter inch and half inch shanks are all in circulation, and none of them is interchangeable. A quarter inch shank dropped into an 8 mm (0.31 in) collet appears to seat, grips on almost nothing, and is thrown at working speed. Check the collet that is actually in the router rather than the model name — plenty of routers ship with two, and only one of them is fitted.

Why this one is on the page

It appeared under a woodworking dovetail search, and the shank size is right, which is exactly how it ends up in a router. The manufacturer never mentions wood. Nothing about the geometry, the flute count or the intended speed comes from woodworking, and there is no bearing or guide to reference a template.

Listing it with that stated is more useful than leaving it out, because the next person who searches for a dovetail cutter will find it too.

Availability

No such listing: the American Amazon shop answers the reference with a search box rather than a page.

Read from Keepa on the day this page was last revised; stock and price both move without notice.

What comes up most often

Can I cut wooden dovetails with it?

The shank will go into a router collet, so the answer is physically yes and practically no. A woodworking dovetail cutter is ground with a specific included angle to match a jig template, and it is run at router speed with rake suited to fiber. A metalworking cutter has neither, and a jig template will not index to it.

What should I buy instead?

A dovetail cutter sold with, or specified for, the jig you intend to use. Templates and cutters are matched pairs: the template guides a bearing or a guide bush of one diameter, and the cutter cuts one angle. Any mismatch between them shows as joints that will not close, which is a slow and expensive way to discover the problem.
