I have some questions about end mill holders.
Sometimes I need to lower my endmill in the holder so I tighten it down at a point that is not on that groove. I do this so that I can clear some tight areas that I need to cut in. It seems to work, I don't go ultra low with it. Do any of you do this or see any problems with doing this?
I was also wondering why there are endmill holders with 2 allen screws, is this so that I can lower my end mill in a lower slot, and have it grab in the groove? Should I get this type of end mill holder in the future?
My other question is on my current end mill holder it seems that the allen screw is getting a bit worn. When I tighten my end mill the allen key is difficult to pry loose from the screw. Do any of you have this problem?
Do any of you know the exact size of the allen key that fits a single screw 3/8" end mill holder?
How tight should I tighten down the end mill? Does it have to be tight or just enough to fit in that groove so it doesn't spin. I could see it holding with it not being that tight.
Can I get replacement allen screws for my end mill holder?
Thanks,
