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

No

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

Put threads in a piece of metal

#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

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.

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

Works great.

They work well.

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

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
