« Part 22: Yonico Router bits Part 23 of Tool Tip series Part 24: Hollow Chisel Morticer chisel sharpening angles found! »

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

Both these images are courtesy of CMT.]

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.

I learned something I didn’t know before. Thanks, Rob. Now, would you mind ‘splainin’ the variations on the orgee bit? You know. There’s a Roman orgee, and something that’s not a Roman orgee. I know that none of the variations involve wearing a toga. Oh. there’s something called a “Reverse orgee. I’m not sure I even want to know what that one is.

Cheers Robert, I get more confused as the days go on, because I have always referred to this, as a Bullnose bit

But if you Google it, the images show both. I guess it depends where you are from, which doesn’t exactly help matters!

Roman Ogee Ogee! not the other.

Gone looking for the reverse Ogee. Romans were a bit funny at times got up to all sorts of strange behaviour possibly the pewter was to blame !
