The photo below was taken with a microscope of a pocket cut.  The size of the cut is about 0.100. Notice that the top of the letter e is not there. This happened because I was using a V shaped cutter with an end point greater than 0.006 with a V angel of approx 35 degrees. The equivalent of using a hammer to thread a needle. I ordered some carbide end mills (square end) and some engraver bits (V end). Should look a lot better with the new end mills.  BTW the end mills are cheep, less than $10.00 

Oh, the microscope was set close to X100.

Next photo taken with IPad to give you a real eye view of the same cut
