I find this to be unbelievably brittle

3/5

In the range of 40 to 10 This will be the second half of 32) work, but it is the second fourth-quarter work The 20 UB thread forming with little forming torque that I broke off inside the hole I was trying to tap was a 20 UB thread forming. As far as cutting fluid is concerned, I do use it, as well as a quarter-inch blade Don't forget to turn and Use the back off method to take a break. UB taps are so brittle that I am inclined to stick with my Widia taps for larger holes, simply because I cannot believe how fragile they I feel bad for you. UB used to be a great name in tooling, and in the past I bought from them, but I won't be buying from them anymore.

This is a great app that does what it's supposed to do well! With this tool, I was able to tap a large aluminum heatsink, something that cutting bits could not do properly

5/5

Then follow it up with a no. With this 25 mm drill bit, I made nice tight threads for my #8-gallon bucket There are 32 screws in total. I am a beginner when it comes to tapping softer metals and this made the job very simple. In fact, this tap was so accurate that I even used a power drill with it, and there were no Using a cutting tap, I was not able to make the same type of holes for practice. In comparison to other cutting taps, the price is quite high, but it was.
