6 Pack Titanium Coated HSS Twist Drill Bit, 3-8mm Hex Shank Serrated Cutting Drill Bit Woodworking Tools for Wood Metal Plastic Hole

I am quite impressed by these bits. Granted, I’ve only used them on thin stainless steel so far, but they performed significantly better than my cobalt coated bits. Shipping was lightning fast and the quality surpassed my expectations.

Put in regular drill and worked great

I was disappointed for find that they do not cut nearly as well as they seem to in the video.

Needed for cutting sideways scrolls in wooden project also great for drilling in wood, cork, plastic. Did not try on metal products.

I have always found myself trying to use drill bits to cut/saw wood after drilling a hole to get a bigger opening for a variety of needs. All you have to do is let the drill bit spin and it cuts, no more back and forth sawing action is needed. So, these drill bits are exactly what I have always needed and they definitely do a better job of cutting the wood than a standard drill bit. The bits themselves are good quality and they are sharp. They are tough enough to last when drilling softer materials, but I would avoid metal. I pretty much insist on carbide bits for metal. I like that they have hex end shafts. This eliminates slipping in the chuck, so they won’t come loose and waste time. I recommend these drill bits highly.

Burnt up cutting uninstalled drywall. Tried cutting outlet holes in drywall prior to installation and didn't matter which bit or speed they burnt up and broke.

These drill bits are very nice in that they drill standard holes without any issues, but they also provide another feature. They can cut like a saw. Once you go through the material with the drill bit, the lower part of the drill bit shaft actually can cut the wood, plastic, etc.. It is a pretty thick cut, nothing like a saw blade, but it is a very convenient feature. The overall build of the drill bits is solid and they cut clean holes. Thanks to their versatility, I would say they are a very good value.

From small holes in hard wood to large ones in a steel column, they performed flawlessly. Very good resistance, low wear, more perforations per useful life. Great drill bits with no slippage in the drill.

I did a little drilling on steel and aluminum and they bits cut metal very well. Like all these "coated" bits, they will wear through the hardened coating at some point and no longer be able to drill metal but still should be good for softer (wood) materials for a long time. But so far, they are easily as good, if not better than my more expensive cobalt bits.
