After posting the blog on the Yonico Bullnose router bits I did some extensive reseach on why this “manufacturing Goof” could happen.
As it turns out I recieved physically exactly what was advertised, albeit description errors which could be explained away in “translation errors” or possibly more correctly possibly lack of technical knowledge on the matter. (My self included)
So what did I find?
1 Router bits with this type of profile come in two forms or styles.
The first being what we all possibly know as a bead and bullnose Router bit. or simply a Bull nose bit.
A Fairly straight forward Bit having a required radius and two parallel and equal width “wings”
The Bead and Bullnose bit
The second is a Corner Beading Router bit
This has the required radius again but the “wings are not parallel or equal in width.
The exact reason for this is unknown to me at this stage and I am awaiting an answer
The Corner Beading Bit

Now the Yonico sets
The Bead and Bull nose Bits code 13515
and The Corner beading bits Code 13516
In conclusion two completely different bits two completely different applications
I will add another blog after I use them.
