Mysterious serrated rim after dimpling
I have a question regarding dimpling. I am seeing a very odd looking serrated rim on the pointed side of the dimpled hole after dimpling and I don't know if this is something that I have caused or is just a result of normal dimpling.
Here was my process:
For match drilling the 3/32 holes I used a #40 new drill bit from pan american and deburred both sides with a dog leg speed deburr tool.
For dimpling the holes, I am using Cleveland's 426-3 spring back dies with a DRDT2 dimpler. I did follow the directions with the DRDT to make sure the ram was adjusted correctly.
I have attached some photos and I tried as best I can to capture the issue. Thanks in advance for your assistance.
