The holes would be about 10" deep. Would the bit wander if hitting knot or irregular grain patterns?

Answer: 
Thank you for your question. The DareDevil auger bits are designed for balanced drilling and can withstand nail hits so it would also be able to handle hitting a knot. The NKST16 has 4" flute length and 7-1/2" overall length. We also offer longer bits, NKMT16 has 9" flute length and 13" overall length or NKLT16 has 13-1/2" flute length and 17-1/2" overall length.

Rated 4.4 out of 5 by 30 reviewers.
Rated 2.0 out of 5.0 by Mixed feelings Didn't work to my expectations. Ended up using a paddle bit. August 9, 2016
Rated 3.0 out of 5.0 by Heavy duty and aggressive... 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. April 22, 2016
Rated 2.0 out of 5.0 by Did not work for me Did not work for my application where I was trying to drill a 1/14" hole. March 22, 2016

Rated 4.0 out of 5.0 by true nail Killer This drill bit was used as directed id still lasting after multiple holes drilled July 27, 2016
Rated 1.0 out of 5.0 by 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. June 30, 2016
Rated 5.0 out of 5.0 by Excellent This is a great tool to have. I bought it for one project & have used it for so many more. May 24, 2016
Rated 5.0 out of 5.0 by Money Maker 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. August 12, 2014
