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

good!

I used this to chase threads in blind holes in an automotive cast iron housing prior to reassembly. It did the job I needed and after waiting for more than two weeks for the local hardware to obtain one of these taps, I had this one through amazon to use in two days for slightly less cost.

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.

Worked like a charm! Very satisfied with this bit

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

Used it to mount a AXA tool post changer.

Worked as advertised. Easy and did a great job.

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

Jan2023: a performer for the price point, cuts cleanly with properly ground/dressed flute edges. Nickel-alloy content similar to more expensive taps thus easier to get started in steel.. At least the ones i received this order werent like the poorly manufactured threads you see too often.

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