How to - carbide tip turning tool

[wood-of-1kind]

The carbide inserts are 30 degrees and that is the best 'angle' to cut wood blanks and even acrylics. The 'round' 18mm (3/4") solid carbide inserts are also manufactured to cut at a 30 degree angle.

Nice looking tool, but does the round insert cut well or does it leave a pretty rough surface, with a good insert you shouldn't need to do much sanding, but the inserts need a 30 degree relief for the best cutting results, which I always thought was the best reason to use carbide but I may be mistaken. the 7 degrees on your 12mm round looks like it would leave a pretty rough surface. I hate sanding almost as much as sharpening, actually I would rather sharpen my tools than sand the wood. (less dust in my lungs)

Does anyone on the site sell these all up round with a handle? Been wanting to try these, but not willing to pay the $85 plus for the massed produced catalog cutters.

With the square bits, the surface isn't too bad. That is:

• treating it like a parting tool to quickly turn down to size works well, leaves a smooth surface.
• treating it like a scraper/parting tool, sweeping left/right, will leave "fur" (like you are cutting unsupported grain), because the corners catch -- unless you are perfect on maintaining perpendicular
• treating it like a skew, riding the bevel and canting 45 degrees, will live a nice and smooth surface.

So, I'm thinking the radiused corners and/or the radiused edge versions of the square cutters might be a lot better.

I've not used the round cutter, as I just got the right set screw, tap, and drill bit today. I just made the tool (picts!)


Picts =
(1) close of of the 3 tools: round, and 2 square cutters; and

I have a question for you. I have a 1/2" by 1/2" x 6" piece of aluminum. Do you foresee any issues with using that to make my own version of a pen pro instead of SS?

I would appreciate it if you would not use the Pen Pro name in describing your tool, I've already had this discussion with Crafts USA and Mr. Nish sent me a very nice letter and compensation. Not trying to be a Hard A$$ but I've spent a lot of time and money developing and establishing it as a brand name, I'm sure you understand!!

I use the radiused cornered ones on mine and they work great. I can't compare to the square corners or full round because I haven't used those... I made a tool similar to yours using 1/2 inch steel and got a little plastic box of 10 inserts for around $15. I've been using mine almost a year now and have probably only used 3 or 4 of the inserts. I just switch after all of the edges "feel" like they are getting dull. I know you can sharpen (or hone them) with a diamond stone, but I haven't even tried that yet. I probably will someday when I use up all of the new ones that I have...

He DID say that he wanted to make his own VERSION of a pen pro, so he was actually referring to YOUR tool, not his own. I would take that as a compliment!
