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

I needed to tap a piece of metal on my shower valve. This tap, along with the handles I bought separately, did the trick. This was a hand tap. But it says its suitable for high speed tapping. Maybe Ill try that, too.

As described, works well.

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

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

Havent break yet

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.

No

I am a Machine Tool Field Service Technician for the past 23yrs and have drilled and tapped literally countless holes (thousands), especially 1/4-20. I install CNC and DRO retrofit systems on machine tools. I purchased 10 of these taps to try and unfortunately, I am somewhat disappointed with their performance. I ended up snapping two of them on their first time usage. For some reason, they just didnt perform well at all. Just tapping through holes in machine tool castings. I dont plan on using the other 8 taps

They work well.

I am very impressed with this tap and handle. I could not believe how much easier it was to cut threads using this setup. I had to keep reminding myself to use oil because this tap would cut decent dry even in 1/8 plate.
