5M's are a doddle, 1/8" ball nose cutter 2.16mm deep plunged in from the OD which you can get off the HPC website.

For 3M's you need a 2mm ball nose 1.28 deep.
That's how mass production looks like
Very good job anyway. I like the side rings which I couldn't be bothered :whistling:
Doesn't fly cutter do job faster???
I ran 300mm/min @ 1.21mm doc and I would dare to do 500 easy. 2mm ballnose could be very flexible as well.
Again very good looking pulleys, John
