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

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

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.

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.

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

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.

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

Good price, fair deal.

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

1/4-20 two flute spiral point taps were too brittle and with too small a cross section to successfully tap a 13/64 hole through 1/4 thick mild steel bar without breaking using a hand tapping wrench and cutting oil. Broke both taps I bought in the same hole (first one I tried them on); could not apply enough torque to cut to full thread depth before the tap broke. I was very gentle with the second tap and kept backing it out. Didnt help. At least the deep flutes allowed me to twist and break up the tap remnant left in the hole with needle-nose pliers. Crumbled like glass. Was able to successfully tap the holes with a US brand four flute taper tap easily.

Good tap. Labeled as HSS. Tapered with two flutes, bright HSS. Cuts fine. No country of origin on tap or package that I can see. Good deal for the price.
