I was quite pleased with the results from using this tapper combo. I was a little hesitant at first because of the speed difference needed to tap vs drill, but it actually works quite naturally. I drilled into tagua/corozo nuts, but I could see this working on just about anything else that needs tapping. I liked it so much I'm going to buy another one in a smaller size!
Just be careful once you get to the threaded section because it will naturally pull as it taps!

Great idea, very poorly executed.2019年7月11日 - 已在美国亚马逊上发表
Broke three threads in, on pre-drilled aluminum with less than 2 lbs on the torque wrench. Save your money and buy better.

If you are drilling into something like a hollow tube, the drill part may bottom out, causing the tap part to strip the threads just made. My opinion is they break a lot easier than a regular drill and tap. I think due to the small diameter between the tap part and Apex driver part. I had the 6/32 ,8/32, and 10/32. Only the 10/32 is still unbroken. At about $10 a pop, for me not a good value.
