Hi all Im working on my practice pieces and have been reading a lot about deburing no more than 10% of the thickness of the work piece. I'm using a 3 flute deburing tool from Aircraft Spruce. With my drill press set at max 3050rpm i was getting a fair amount flashing on the backside on my #30 holes through my angle. I debured as lightly as i could due to the sharpness of the new tool but i noticed two things
1- The round hole no matter what i tried was turning the chamfer into a rounded triangle due to the three flutes.
I have a 6 flute which will cut down on chattering but am unsure of the angle and don't want to chance it. Is a single flute (round hole ) cutter in these sizes avail?
Iv seen the drill mounted spring loaded debur tools that do both sides at once but there pricy, only work with one size, and I haven't heard anyone here raving about them.
2- To pass the finger nail test 3 and sometimes 4 turns of the tool were needed which worried me due to the 10% rule. heres the angle with what i think are over debuted
Notice the chattering.....
I also want to ask all about a switching to a reamer. Cost? benefits? RPM ?
Thoughts? Pics of a perfect marginal and scrapped hole?
