Rated 5.0 out of 5.0 by BobDoesntTell Bosch auger drills
I needed to drill four parallel holes, 12" deep in wood. The wood grain tends to make the auger move around as it drills. I don't have a drill press that would allow me to keep the drill in line, but because the leading edge of the augers are tapered to a smaller OD at the tip, I could start the holes at 1/4", which I could control by hand. Then I could use the Bosch augers to successively enlarge the holes to 1-1/8". An ordinary auger has a tooth on the leading edge of each spiral, which gives a clean cut on the back side of a hole. But for my purpose, the teeth make an ordinary auger impossible to control.

Didn't work to my expectations. Ended up using a paddle bit.

If you are looking for an aggressive bit that will go through anything, this is it. If you're looking for nice clean holes, this isnt it. Looks like a shotgun blast through the hole, whereas what I need is clean holes. However, if you are looking for something that will last even longer than your typical nail eater bits, this will suit you just fine.

Rated 1.0 out of 5.0 by Rich Not what I expected
Was recommended by a sale associate and not happy with product. It never drill through the wall, not even after making a pilot hole. Bought a regular drill bit (long bit) and it worked better.

I bought this drill bit to replace old worn out ones and get my AV business moving forward. I often am running wires through walls and need to create larger or new pathways. This bit makes that job fast & easy! I try to avoid nails because they aren't good for any drill bit, but so far this beast isn't showing any problems. I've used it on a couple of jobs and drilled quite a few holes and expect to use it on a few more at least.
I look at all my tools as a job cost. Even if I only use a tool once, if it makes me more money than it costs, it's worth it! This bit earned it's keep on the first job. Now, it's just money in the bank. In my business, where labor rates are at a premium, saving an hour is significant! This bit is one of my best workers! I expect to buy more.
