Here are a couple of photos of Drill Points for push drills ( 46 pieces ) that I decided to try in the tumbler. The results are good, not dramatic, and all will now take a bath in WD-40. These are the smallest pieces I have tried, a bit of a pain to dig out, but it was time to clean the bowl, anyway. Regards, Lou
Do you need to sharpen them afterwards?
Hello, I clean these for resale/my collection. I don't think the tumbler dulls them any more than before they went in. Regards, Lou
