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

rare size tap, did what i needed it to

This tap worked great cleaning-up the treads on my old car rivnuts.

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

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.

Fast Prime delivery and solid unit. Thank you

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.

Works great for the price

Worked as advertised. Easy and did a great job.

I really wish they could have been supplied in high speed steel, instead of carbon steel. I tap some tough materials, and I have concerns how long these will hold up.

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