I know you dislike youtube, but:
I will almost always watch a YouTube video if it is recommended to me by someone who was thinking of me personally. So I watched the whole video. Thank you.
I had them recommended to me by several people, and have yet to grind my own single point tools, just the 1/4” square for the tangential tool holder.
I ordered both LH and RH, but I could have gotten away without purchasing both. Postage to Canada was horrible…
In my opinion, the only thing unique about this tool is the way it is held and the relative simplicity of the grind.
What most people don't realize is that it is the top of the tool that does the cutting. That is true of this tool and almost all tools. However, the way this tool is held and ground makes it much easier to see that and also easier to use too.
I also noticed that they did use the tool as a shear tool and mentioned the superior finish that this method produces. However, the shear angle they used was much shallower than what I normally use. I will have to try that to see what kind of difference it makes.
I don't know if I like the way the tool is held. Pinched like that in the holder along the same line as the cutting force might tend to move the tool in the holder - especially on interrupted cuts.
I would also think it's not as universal as they imply. The tool holder gets very close to the work and might interfere on some types of cuts.
It is the perfect tool when used with a rocker type tool post though. That may even be where he got the idea. I have some old rocker tools that hold HSS tool bits just like that when they are turned 90 degrees from the design intent.
Overall I like it. I'm not convinced that all the stated advantages are real though. Sounds more like marketing hype to me. Nonetheless, there are enough obvious real advantages to make it well worth trying. I'll have to make a holder.
Two questions:
What is the front angle from vertical? And what is the side angle from vertical when the tool is used for facing?
