    Cool. That was super informative and nice that it compared the different shapes to each other. There was also some good information on selecting an end mill. Thank you for sharing the link I never would have come across that on my own.

    Carbide insert question

    Is this paper there to do what I think it is?

    My guess is the burnishing ring from the bearings isn't as bad as seeing serrations from the chuck jaws.

    India stone grinding jig

    This might be a stupid question but would just using a much finer grit stone do the same thing as far as having less bite? My only experience is with using stones for sharpening so I am trying to rap my head around the differences. I guess I should also ask are these stones different from...
