Drill America1/4"-20 UNC High Speed Steel Tap Set

Got these on Sunday, used them on Monday. Fast delivery, well packaged. The taps worked very well for retapping existing holes. They made the install job easy. I would recommend this tap set.

Decent tap set. I got a little greedy and broke one but no big deal. Cut really good and they have lasted through a lot of holes.

This 1/4 inch tap works great.My DR. Pilot trimmer Mower. Was a bad purchase.The replacement $100. plus power head had to be tapped. It is made out of aluminum.This made it possible to fix my walk behind trimmer.

Bottoming taps are the way to go for rethreading. These are sharp, accurate & suitable for steel as well as other metals.

Drill America seems to make good taps and drill bits . They hold up well

Id never used a tap in my life before and to save money I figured now was the perfect time to learn. This set is to be used with a hand tap wrench which I also bought from Amazon to be able to use these. In this set you get three different taps of the same size. One is tapered and is the one that is used when starting a new hole to be tapped. You then have another one that is basically a tap used to recut threads that have either become rusted or damaged in some way. And finally you have an end tap, that is this is the tap that you can run through the entire project and then back out to make sure that youve cleanly cut the threads. One thing I did learn about doing this is to take your time going a quarter turn then backing out then starting again to cut more thread. You do this until you have completely gone through the piece of metal then swap over to the end thread. Take some patience and time but its all worth it in the end.

high quality tap, would buy again.

I only needed to use it once so I dont know how it holds up, but it did what i needed it to do.
