What do you guys use for this? I wasn't stupid enough to try to use my carbide boring tools and have tried a homemade HSS cutter made from an end mill but I'm not sure what profile I should grind on it.
The one I have cuts well but it seems to hook into the poly and it is all too easy to cut oversize.
Any suggestions?
Thanks!
