Drill America - POU1/8NPTW/DRILL 1/8" Carbon Steel NPT Pipe Tap and R High Speed Steel Drill Bit Set, POU Series

I haven't been using these for extreme circumstances but I will say that I have been using this 1/4" set as well as a 1/2" set and they have been doing an excellent job! Very well made and they have a professional finish. Absolutely cannot beat the price!!

I used this to drill and tap an aluminum water pump housing. I know aluminum is not a very tough metal but never the less the drill did great and didn't get gummed up and the tap worked well too. Nice set. I just wish they made a complete set with drill and taps (they only sell a tap set).

I am not sure how well the bit and tap would hold up for regular use, but I just needed it for a one-time application (drilled out broken brass pipe nipple and retapped). It worked well (using plenty of oil and taking my time), and it was far less expensive than buying a set of NPT taps that I will probably never have a need for going forward.

Worked like a charm. Used it to drill a hole on my 01 mustang gt intake manifold for the thermostat sensor.

The drill bit was sharp and useful. The tap was not very sharp (used on brass ) and the work was laborious & slow !! Should come in handy down the road

Works great for fixing a messed up pipe threaded block

Used it to fix a broken engine block coolant port on my 1997 Chevy C1500. The old hose coupler snapped and half of the coupler got stuck in the screw hole. I drilled the leftover out and used the tap to get rid of all the stuck threading!

Worked just fine to drill and tap a new air output on my compressor. Package well and came with oil on it to prevent rust.All in all, good price and got the job done.
