Cad doodle (CCGT 21.52 insert)

My latest Cad doodle, a CCGT 21.52 insert with 15 degess of back rake. I have no idea if it would actually work, but is was fun to design. If you want to take a look at it in 3D you can download the RhinoCad file here.

Carbide tooling finally

Finally I have carbide tooling that I can use when I turn harder materials, something I find myself doing more often lately. While visiting family in central Pa. I stopped by grizzly and picked up a set of Glanze 12mm tool holders. I took the following videos while I was trying out some inserts i purchased.
