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

What the specification says

Seven bearing-guided roundover bits with 8 mm (0.31 in) shanks, radii of 2, 3, 4, 5, 6, 8 and 10 mm (0.39 in), YG6 carbide cutters on a 1045 hardened steel body. Part number NI0075-7P. No EAN on the listing.

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 a set makes sense here

Sets are usually a way of selling profiles nobody uses. A roundover set is the exception, because the profile is always the same and only the radius changes — there is no dead weight in the box. What you are buying is the freedom to try three radii on an offcut before committing to the workpiece.

Availability

Catalogued and unsold: the American Amazon shop lists the reference with nobody behind it.

What comes up most often

Which radius should I actually use?

The small ones far more than the large. A 2 or 3 mm (0.12 in) roundover takes the sharpness off an edge without visibly changing the shape, which is what most furniture wants; 8 and 10 mm (0.39 in) read as a deliberate design decision. Buying the range is how you find out which one your eye prefers, and that varies by piece.

What is the warning about the shank?

The manufacturer notes that if the bit is gripped outside the marked line on the shank — for instance when someone puts it in a drill chuck rather than a collet — the shank can bend. That is worth taking literally. A collet grips the full length of the shank; a chuck grips three points, and a bent shank at router speed is dangerous.
