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

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.

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

Really nice quality tap for the price.

Havent break yet

This tap held up and did not break when using. I had broke two other brand taps and this tap held up and did not break while using it on aluminum.

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

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.

Good price, fair deal.

Works great.

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.
