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

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.

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

I’m not sure how long it will last but I don’t use taps very often and it served the purpose I needed it for

good!

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.

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.

Fast Prime delivery and solid unit. Thank you

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

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.

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.
