The end of it Good value and a genuinely versatile drilling guide, provided you accept that the bushes are a consumable.
Every figure is a manufacturer specification, read off the
listing itself, and the judgments are ours — drawn from how the
specification behaves in this class of machine and from what long-term
owners consistently report. Where a figure is missing, we say so rather
than fill it in.
What the specification says
A drilling jig for dowel joints, part number 7581-00, from kwb. A rotating disc
selects bushes from 3 mm (0.12 in) to 12 mm (0.47 in) — 3, 3.3, 4, 4.2, 5, 6, 6.8, 8, 10 and 12 —
and the jig is rated for corner, angle, T and face joints with 6, 8 and 10 mm (0.39 in)
dowels. The body is hard plastic with a rubber anti-slip face. In the box: 150
wooden dowels and three CV twist drills in 6, 8 and 10 mm (0.39 in).
Dowels and pocket holes solve different problems
A dowel joint is concealed, symmetrical, and strong in the direction the
grain wants to be strong. It also has to be laid out accurately on both
halves, because a hole in the wrong place cannot be moved. A pocket-hole
joint is a screw driven at a shallow angle into an oversized bore: no
clamping time, no glue-up to plan around, and a visible plug on one
face.
Neither replaces a mortice and tenon in a chair that will be sat in for
thirty years. Both are entirely sound for carcases, jigs, shop furniture
and repairs, which is most of what actually gets built.
The brand on the box
The search asked for a Wolfcraft product and this listing is kwb. Both make
jigs of this type and they are not the same company. We name what the listing
names, because a reader who ordered expecting one and received the other would
have a legitimate complaint, and the difference is invisible from the search
results.
What ten bush sizes are actually good for
Dowelling uses three of them. The other seven turn the jig into a general
drilling guide: a way of getting a hole perpendicular into an edge, a face or a
tile without a drill press. That is arguably the more useful function, and the
rubber face is what makes it work on surfaces where a bit would otherwise skid.
The good side, and the catch
Strengths
Ten bush sizes, so it doubles as a general drilling guide
Rubber anti-slip face, which lets it grip tile and stone as well as timber
One reference and one EAN across all six markets
Compromises
It is a kwb product, not the Wolfcraft the search asked for
Hard plastic bushes wear, and a worn bush drills a sloppy hole
Corner, angle, T and face joints only — no edge-to-edge alignment aid

What comes up most often
Is this a Wolfcraft?
No. The search asked for one and the listing at this reference is a kwb Dübelprofi, part number 7581-00, under the kwb brand. Different manufacturer. We review the product that exists at the reference.
How long do plastic bushes last?
Longer than people expect and not forever. A twist drill running against a plastic bush wears it slightly oval over time, and an oval bush lets the bit wander, which is the one thing a jig exists to prevent. Hardened steel inserts are what the more expensive jigs have; at €19 this is the trade.
What is the rubber face for?
Grip. kwb lists it for drilling on smooth surfaces — tile, mineral composite, porcelain — where a jig would otherwise skate on the first turn of the bit. It is useful well beyond dowelling.
