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

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

Worked like a charm! Very satisfied with this bit

Works great for the price

I used these to prep a new steel bicycle frame derailleur nut. Because the paint was in the threads, I could not properly screw on the derailleur. I used the more blunt one first, as I had already crossed the threads with repeated failed attempts, then I proceed to use the sharper one for a final cleanup. Very effective! Derailleur screwed right in afterwards.

rare size tap, did what i needed it to

i like that it was cheap and they gave you 3 taps. it did what i needed it to do but was starting to show wear immediately, probably not an heirloom tool. if you need it for a one time use then it may suit your needs

Would not retap nut but it may not be taps fault this was a special type nut, keeping anyway for what ever I may need a big 1 1/4 tap for. Nicely packed in its own plastic box.

My first/only use of these so far was to tap some holes in brass, drilled about 1-1.5 inches deep down the length of 2 brass rod (so the holes were not through-holes, and required bottom tapping). These got the job done with no fuss. Mileage may vary on harder metals, but I had no problems getting these holes tapped perfectly in brass with these taps using a little cutting lubricant (did them slowly by hand). For the money, I felt it was good value to get all 3 varieties.

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

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