Rated 5.0 out of 5.0 by Keith An Augers auger
I use augers frequently as I salvage treated lumber from old decks and re-use the wood to make anything from wishing wells to storage sheds.
As with any used wood, more than likely you will need to remove old nails or screws in order to use a saw on it and also for obvious safety reasons.
I have 2 different hand held metal detectors I use to locate old hardware within the salvage wood. As hard as I try, inevitably a nail or screw gets through my process and magically finds it's way in front of a saw blade or auger I'm using.
I've ruined many auger bits and saw blades over the years. Augers are the most unforgiving as when the auger meets a piece of hardware, the hardware wins. I have never had any luck trying to salvage the auger tips, so they get put into the bent nail container.
I saw these marketed as nail resistant with 3x the life compared to other brands. I'd be happy with 2x the life. I wasn't able to review these by drilling into wood with nails, but I did try them on some salvaged treated lumber and liked them.
This is a beefy auger bit.

I got these thinking they might be a good alternative to spade bits or forstners for finish woodworking. I was wrong about that--they do not make particularly clean holes. But they make holes fast, and they can go through just about anything. These won't do finish work, but they would be perfect, say, for drilling holes in nail-filled studs in a 100 year old house to install new wiring.
Note that you cannot use these in a drill press--It says that right on the package, but I'm not the smartest man and I missed that part. If you do use one in the press, it will screw into the wood and pick it up off the table and spin it all around. After I figured that out, I chucked it in my corded DeWalt drill and went to town. As you can see in the pic, it makes some pretty rough holes, but makes them quickly.

Rated 5.0 out of 5.0 by HandyAndy2010 Meaty, Heavy Duty.
These are not your average Augers. At approx. 8'' with a 2 1/4'' shank, These are some Heavy duty bits. They also have an octagon shank for better torque.
Each bit, 5/8'' 3/4'' and 1'' have shank diameters that correspond to the size of the bit. I am using 1/2'' drive when operating them and they are powerful. These sport a reamer edge for cleaner holes and will even clear existing screws and nails.
Spiraling tips help keep the tip on point. No slipping here. Another great component from Bosche

Rated 4.0 out of 5.0 by Popanuge Good bits - with a word of caution
I needed to run some Ethernet cable down into the crawlspace and up into another room. The obvious choice was to attempt it with the tools that I had at hand. Alas, my aging 3/4" spade blade was no match for my oak hardwood floors.
On the other hand, the 3/4'' Daredevil Auger made short work of the drilling. I did not experience the rough, jagged finish that other users reported. Fortunately, I did not encounter any nails either although, the manufacturer claims that these bits are designed to withstand some nail contact.
The 3-Piece set also comes with a 5/8" bit and a 1" bit. At just under $30, I think they represent a decent value.
The packaging is that horrible heat-sealed plastic that you have to destroy in order to open. I would have liked to have seen some kind of reusable storage to keep the bits in.
A word of caution before purchasing these bits. The chuck on your drill will need to be able to accept the 1/2" shank of the bit. A chuck *that* large is not that common in the Average-Joe Homeowner's tool box. There is no mention of this important requirement on the packaging.
Robert Bosch Tool Corp. is based in IL, USA. However the bits are made in China.

These are serious tools for making rough holes, they dig into wood quickly and chew through softwood. The tips are hardened to resist damage from embedded metal; I can't vouch for the tip hardness. They are probably not recommended for use with cordless drills, they need the torque of a corded drill or the drill will stall. Plastic packaging was difficult to open and not suited to reuse.

Rated 5.0 out of 5.0 by wcsd for rough work
These bits are no joke. From the hexagonal shank to the double cutting edges to the reamer edge and reinforced tip and spine, this is what you use for rough work such as running electrical or plumbing through stud walls; standard 2x and 4x wood framing. The short bit makes it easy to navigate close quarters, but you need bits of all sizes for different applications.
A 1/2" low speed drill is a necessity, I use a "yellow brand" spade handle drill but carefully, because even though these bits are designed to eat through nails you really have to expect that your drill will bind up with all that torque, so when it does it doesn't break your wrist.

I had to install a 5/8"dia x 6" long all thread bolt in a barn's post & beam. I used the 5/8" dia. bit, from this set, to drill the hole. Part way through the post I hit a 20 penny x 3/16"dia nail. The drill stopped. I reversed the drive, backed the bit out a little, then started forward again. I continued drilling using a low speed, light steady pressure. The bit cut through the nail & continued out the other side. The bit suffered minor nicks on the cutting edges. On subsequent holes the bit cut through them as though it hadn't been damaged.

Rated 5.0 out of 5.0 by EricG Robust augers drill holes effortlessly
I have been replacing my old spade drill bits with augers- there really is no comparison. These augers cut almost as smoothly and accurately as my Forstner drill bits. They pull their way through thick wood with almost no effort, while the spade bits required constant force. This is especially useful when you are standing on a ladder.
I make a point of removing nails before drilling, but I relieved to know that if I miss removing a nail these augers will make short work of it.
I have always had good luck with Bosch tools, and I am confident that these augers will live up to their name.
