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

The price is right but you get what you pay for. It seems like a Chinese tap to me. Broke one after 14 taps. Set up on a Bridgeport, low rpm should not have been a problem.

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.

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.

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

I liked the concept but both of the taps broke when I first tried to use them. I used the #7 drill bit supplied by the same company too. I used tap magic religiously and tried not to force the tap while breaking the chips... definitely a waste of money. At least the drill bits are holding up since they are suppose to be m42 cobalt steel. Now on the hunt to find a different brand ¼x 20 tap.

While taps break, it sucks this one broke so quickly. If I had more than one to review I would either give it less or more stars, but since I cant properly test if it was just a fluke, I give it 3 stars.

ordered a pack of 12 taps. assumed they would all be right hand. some of them were left hand and useless.

As described, works well.

Havent break yet

Nothing to dislike. It was properly packaged, arrived on time, looked pristine, and worked like a champ.
