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

Works fine

They work well.

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.

this tap bore out several taps in aluminum almost to the nuts and even the last one felt like butter. itll make you wanna drill extra holes just to tap them, its that good. steal this companies money LOL, these things are worth 3 times the price they charged me

Working in an elementary school, I discovered that the adjusting screw for desk legs that had been used werent really the right size. Turns out there was no right size, but this tap made short work of producing a tapped hole that perfectly fit the available screws.

Really nice quality tap for the price.

Put threads in a piece of metal

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

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

I got the 1/4-20 tap and it was very sharp and strong. Just remember when tapping by hand, be sure to use tapping fluid and to back out your tap and clear out the chips as soon as you see or feel the tap itself starting to twist, and repeat until done, dont push the tap any farther than that or you risk it breaking it. I used this tap in 8 holes in 3/8 in thick steel of my 1,000 lb capacity garden wagon frame, and it was still sharp as new.
