Drill America - DWT57129 1/4-20 High Speed Steel 2 Flute Spiral Point Tap, DWT Series

Worked great on redoing the pistol grip threads on AR receiver.

I threaded about 5 inches of hole before she got slow. Was able to touch up with angle grinder a few times and get another 5 inches of tapping. I was impressed that the tap didnt require much backing up to break the cutting, was able to drive ahead for many turns at a time.

Havent break yet

As described, works well.

They work well.

Quick shipping. Only used it for a single cross threaded hole. Fixed my issue in 2 minutes. So worth the $7!!!!!!!

Really nice quality tap for the price.

#8--32 tap worked well. I used as a re-threader in an old junction box so I could use two semi-corroded screw holes

works as advertised

It broke on me but to be fair you take a risk each time you use a drill instead of a tap/die bar. It cut through thin gauge steel (my original reason for buying it) without tap fluid easy. It made it through 10 out of 12 deep aluminum holes with fluid before snapping. To be fair, and hence my 5 star, I knew the risk from using a drill for it and it was an afterthought. Some slide/rail parts I got only had half of the holes tapped for whatever reason, and I noticed they were 10-32 so I finished em with this guy. If I had an originally bigger purpose for purchasing, I would have paid $10 for a solid tap bit, but since I initially bought this for literally 4 tiny holes, and it was $3, Ill give it 5 stars
