Drill America DWTT1/2-13 1/2-13 Carbon Steel Taper Tap (Pack of 1), DWT Series, Uncoated (Bright)

Nice, easy and quick transaction. Tap set was perfect for reclaiming a 10-24 thread on a tool that woud have cost $50 or more to replace.

This procuct met all of my expectations and was useful in the application I needed it for.

You must choose which type of starter threads is best for your needs. Seven thread taper is for cutting new threads in soft metals, cased iron, or plastic. Use lots of oil. The shorter-length starter tap is best for cleaning existing threads. The super short starter thread tap is for finishing bottoming threads. I showed this tap to my friend that makes taps for a living and he said it looked ok but his stuff was much better and made of M2 tool steel. Then I told him the price and he said no, he couldnt do that for that price. Couldnt even buy the blank steel needed at that price.

I expected a cheap tap, given the price, but this 1-8 tap still disappointed me. I used it to chase an already threaded hole in cast iron, way down in a deep well. It would not fit in my Lisle tap socket. The nominal spec for the flats on a 1 tap is .600; I measure my other 1 taps at .595+-.001. This one was .603 one way and .602 the other; too big for a tap socket. I had to mutilate it on a belt grinder to get it to fit.

Good Value.

The bottoming tap cutting edges were not formed properly or were rolling over.

I didnt need all 3 but it was a size I didnt have out of my 500 taps I have so I figured get all 3 . For me this is the size for my 3point hitch on my tractor

Used it to mount a AXA tool post changer.

I bought the set for a one-time use of this odd size (M13x1.5). Price was right at about 1/3 the cost of other taps but the steel isnt top quality. The worked well to cut the threads I needed in cast 6061 aluminum. They came out clean, sharp and accurate but I dont think the taps will hold up for the long haul. Theyre a very good value for limited use. If you need to cut a lot of threads or plan to keep them for years, youd be better off spending more and getting better quality tools.

I use this tap on a small block Chevy bell housing just to clean the threads if they get rusty or whatever just for clean up and Ill get a good bolt makes a good bolt thread for your new bolts
