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).

Just worked great tapping aluminum

The end of the drill flutes had a small burr, recommend dressing it with a stone (or sandpaper) before using the drill bit. The same for the tap, the cutting edges look slightly rounded.But for the price they are a reasonable quality, and Im only using this in aluminum.The tap doesn't have much lead in taper, if you are using this every day I would suggest a higher quality tool.

High quality pipe tap and matching drill bit. Both are very sharp. A great pair for a great price.

Only needed to drill and tap one hole in mild steel. Opened up hole in stages to 11/16", then used the 23/32" drill to prep for the tap. Then tapped the 1/2" NPT threads to gage. Went in steps, no more than 1/8" depth at a time, then pulled out, cleaned tap and hole of ANY shavings, lubed tap flutes all really good then back in. Don't forget to always cut for 1/4 turn then back out a full turn or so, a couple of times during each cutting portion. Threads are perfect. Drill and tap are both still perfect. Used Tap Magic for both drilling and tapping! ALWAYS!!!

Excellent quality drill and tap use this to drill out and tap the air drain on the bottom of my air compressor after the old one broke off

As advertised
