I used these to drill holes in a plastic box to build an 18 volt to 12 volt converter. Holes for 12 volt cigar type receptacles, holes for switches and jacks, and a large irregular shaped hole (drill several holes then cut to connect and shape) for a battery adapter. This product made my work a lot easier than the way I had to do this previously. Godd product for the money, at least for my purposes.

Me and another friend of mine saw the add. One the first things that we were surprised was the price. Normally you find it in stores at $50 or $70. So, I decided to buy one set. He asked me to buy onether and ended buying two sets. When we began to test them, they performed pretty awesome. Every drilling was smooth and precise. An excellent quality product that I would recommend to other people. If someone else decides to buy it, don't hesitate and give it a try. Regards to all.

The bits work great, the punch not at all.

These drilled through angle iron with no problem. They still look good and have more life in them. Jury still out on the longevity and durability.

This bit set is a regular purchase for me, I use them a lot and these last at least as long as any other step style bit I have used, even those at 10x the price. My only disappointment is that this particular set came with a pouch instead of the aluminum case as advertised. Sadly I just realized this as I went to order another set and wanted one with a case and not a pouch.
