Drill America POU Series 1" NPT Tap and Drill Set, 1" Carbon Steel NPT Tap and 1-5/32" HSS Drill Bit w/ 1/2" Shank in Plastic Case

Good price, needed the tap to make new threads in a aluminum caliper for a bleeder screw repair kit. Turns out I didnt need the drill bit as the hole was the perfect size , just ran the tap down to the bottom of the hole , installed the repair kit , worked for me. The drill bit is still great to have if you need to drill out some other kind of caliper or whatever needs a repair kit etc.

Como debe ser.

These work Great. This isn't a 5-minute job You must be very careful slow and steady and kept the tap clean when using it. Working in and out numerous times backing out and putting in very good price for the size.

Quality is good for what we paid for and what we do with it.

This is exactly the right tool for pipe threads 1/2” The price is very good and the combination drill/tap is great for repairs. Most threads in plumbing are in bronze and soft metals, so it should last a very long time Quality is very good (carbon tap) for non-commercial - highly recommended
