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

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.

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.

Worked as advertised. Easy and did a great job.

good!

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.

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

Bought to thread in a Grovtec Push Button Base into a Luth-AR MBA Buttstock. Easy peasy

I ordered a BOTTOM TAP. I received an angled spiral cut tap which is not what is described, not what I ordered, and not what the protective box it came inside said it was. I was able to get the job done but had to modify the item I was working on to do so.

This is a taper tap which easily advances in a prepared hole of correct size or for use in chasing damaged threads. Good value for the money.
