I got these for DIY home renovation. I've used them to drill through joists and beams to run wire throughout my house, and they've worked great. Before, I was using a paddle bit as that's all I had (I'm new to all of this) and it took a lot of labor, effort and about 20 minutes to go through a joist, with these auger bits it took this bit about 5 seconds.
Other use, there were 3 large stumps in the lawn of the house I just bought. Saw an idea on a website that suggested drilling into the stump and putting in some chemical to rot the stump out. I decided to try doing the pilot holes with these bits. Worked amazing until I hit a soft spot in the stump and got a bit stuck! Whoops, that's the downside of how efficient these are. Luckily, after using the pilot holes i had drilled and a sledge hammer and splitter I destroyed the stump and took the section with the bit and cut it out. Afterward, the bit was still in perfect shape - it was all the way in there as my drill went flush with the stump. These are fast, and sturdy.
