I wasn't sure if I could use these drills but I used the same drill to cut 20 holes in an aluminum profile and each hole came out perfectly (I cut in a hole already drilled in the middle, I didn't use the drilling function of this bit). The only downside is the bits are shorter than I need so I had to cut the last 10mm with a hand tap but it still saved a lot of work and was a lot easier than a hand tap. For those who are skeptical, these drill bits and taps work, you just have to move slowly and lubricate the bit.
