I was not easy on this tap. I bought 2 assuming I would break one but didn't. Managed to tap 192 holes in 1/2 inch plate 2024 aluminum in about 4 hours. Some I did by hand and some I did in a drill press (had never user a drill press for tapping holes and was mildly nervous so tried by hand at first). Didn't have to back it out at all, just rammed it through and it worked great.

I bought three of these because I was sure I would break at least one. Tapped 140 hole with a mag drill, didn’t break any. Pretty good I’d say
