I used this bit to drill six 1" holes through a 30" diameter Red Oak tree to cable it off as a result of storm damage. I was skeptical at first seeing the bit when it arrived. I thought for sure it would twist off half way through the tree. But after using it, and taking my time with each hole being sure to clean out the shavings with each few inches of progress while drilling, it worked great! A testimony to the "Made in America" logo. I got all six holes drilled, saved the 100+ year old Oak tree, and the bill is still good for the next job. Well done Eagle Tool US! My story would not have had a successful ending had I bought the "Made in China" garbage at Home Depo or Lowes'.

I added an external duplex wall outlet. Power for it was taken from an existing interior GFCI outlet. The 1/2" x 36 inch long drill bit was exactly what I needed to get the job done. The 12/2 UF-B cable had to go from the interior outlet, down through the sub floor and sill (approximately 4.5-inches of wood). This got the 12/2 into the crawl space for easy passage to the exterior wall. While drilling I felt the bit strike a framing nail. But fortunately it wasn't a direct hit. So I was able to get past it without too much trouble. But I suspect the drill bit lost eight of its nine lives from the encounter with the nail. This project would have been more difficult without a long flex bit. No drywall repairs needed, everything was done inside the existing wall and in the crawl space.

Used this to run a cable down a wall with a firewall that was 5ft from the top of the wall from the attic. I did have to use an endoscope to find the hole that was drilled in order to thread the wiring through the hole.

Very flexible and did the job. Excellent tool for perforating holes in a small in-ground pond liner to turn it into a flower bed instead.

Brought these to drill holes for threading wire through studs to install my recessed ceiling lights. For the most part, it works. Drills through the studs (4x10s), though takes quite a bit of error. The screw teeth at the tip deff help with the grip which is great. I wish the drill bit shank were a bit shorter, cause it gets a bit hard to pull it out should I need to do adjustments. The hole at the back is good for putting your romex in to pull through to the other end. However, do note that the hole drilled is only big enough for a single 14/2 romex wire. Any thicker, and it won't fit. Even for 14/2, you have to pull quite a bit for it to go through. So if you need 14/3 or 12/2 or anything larger, get a large diameter bit.

Very useful tool

I bought this for a project I've been doing at my house, running wires for a home theater system through existing walls. I was planning on using it to drill a few difficult locations. One was through the top plate on my wall, the other was through the joists on the ceiling to push the wire through. Well, for the top plate, the wall was an exterior wall and had insulation in it. I tried to use this to drill up through the plate in the wall, but it just got caught up in the insulation. I was also using a bumper ball and placement tool. So that didn't work, I ended up cutting a hole in the ceiling and drilling down from above. As for drilling through the joists, turns out I didn't need to. I didn't realize I have engineered truss-style joists in my ceiling, so no drilling necessary. So in the end I didn't need this bit. But I will say it is very good quality and not too hard to use from what I've seen, so for that I will give it five stars. I will recommend you get the placement tool if you're using it on existing walls. The placement tool is very useful for getting a vertical hole (and not drilling through your siding). I almost wish I needed this bit for something. Oh well, I will save it for another project.
