I probably wouldn't buy again except if I needed the inserts. Doesn't come with everything needed to be able to use but the tap was ok quality even though i wouldnt use it much more than 10 or so times just to make sure... Inserts are great and for the price can't beat. Other name brand inserts cost a lot more and you don't receive 8 of the same size ones usually like you do with this. Would recommend just for the amount of same size inserts you get for the price.

After the tap went through I was just left with a giant hole with no threads at all. The insert just dropped right in. This tool is absolute garbage and will ruin your threads. DO NOT BUY THIS!!!!!I now have to replace the whole head do to this cheap trash of a kit.
