I like them very much

The case is quite cheap (the latch fell off immediately). To test, I used a small drill to drill 1.25mm thick aluminum with a cordless drill. With moderate pressure it took longer than expected, but when it broke through it reached about 3/4 of the threaded portion of the bit; I turned it over and got a threaded hole and a noticeably blunt point on the bit. I then used it as a pilot hole for a 1/4" drill - that didn't work either and the hole was too big and poorly threaded. I tried the 1/4"โ€ฆ

Pros
  • Combined drills and taps
Cons
  • There are doubts

A Good Set of Bits - Taps for Threading

Drills are one of those things that vary wildly in quality, and although sometimes how much they cost matters, especially when used for a specific purpose , Cost is not that important for a non-professional DIYer like me. I bought very expensive quick change shank drill bits and they broke or jammed the first time I used them. At this price, this 13-piece set costs just over two dollars and is an incredible bargain. I'm pretty quick with drill bits and I prefer these types of quick change drill

Pros
  • Industrial and Scientific
Cons
  • I'll Write Later

Maybe if you're very careful

These types of drills/taps have been around for a while and I figured they've probably gotten better over the years. These special drill/tap combinations weren't so bad at first. I used a 1/4-20 drill and tap combo in a 1/4 impact driver because I thought the driver would slow down when it reached the tap section and I would have better speed control. I first drilled a 1/8 pilot hole and then used a drill/tap to finish the hole. This worked well for 2 of the 3 holes I drilled in 1/4 gauge steel

Pros
  • Cutting tools
Cons
  • Not as thick as other picks
