This is the result I get when i give my Avery speed deburring tool a 360 around a drilled hole.
This is a #40 drilled hole deburred and then dimpled on DRDT-2. Dimple was done to improve visibility of the jagged edge of the deburred hole.
I have tried using light pressure and heavy pressure fast and slow with similar chatter. Do I just need to buy a new 3-flute cutter? This tool was purchased new (in 2007) and has only been used on about 100 or so holes. If this is normal and I am just looking too close, I will be thrilled with that answer.
I am seeking your collective advice as I am now frustrated before I have even started (this is a piece of scrap from a 2007 Oshkosh sportair workshop that I was using to experiment on this afternoon). I have also been having some issues with my drilled holes not being round, but hopefully I solved that with a new set of drill bits.
