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.

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.

I am still in the process of running ethernet throughout my house, so I have only bored 10 holes with this so far. I can tell the bit is starting to get dull (going through 4" headers and footers for each hole is laborious even for my electric drill). The biggest issue I've had with this bit is the smooth shank. I have to crank my chuck key down with an unreasonable amount of force (more than I've ever had to, even for drilling through masonry) to stop the smooth shank from slipping in the drill. When you're up in the attic and its 150+F, the last thing you want is to have to pull your bit out and re-chuck it, let alone if it falls through wall. Note: This bit is obviously not designed for professionals. It is designed for people that have one specific project and are not looking for a $100 installer bit. It will likely last the duration of this project, but it will not have much usable life in the bit after that.

I was installing some electrical sockets in a bedroom and was unable to drill a hole behind the socket and down through the floor board using a standard length flat bit, even after extending the bit, I could not get the correct angle for the drill. However after some research I came across these drill bits and they are brilliant due to having some flexibility in the shaft I was able to guide the drill into the correct position to allow me to drill an access hole for the cable.

I was expecting the bend on this to be a bit more flexible, but its just enough to get into a stud wall, through a single pattress box size opening. Used a couple of times now, wish i'd bought the slightly larger diameter, as i'd done the rough sizing calculation in my head.

I bought this because I use a fish bit at work and needed one for home. It is very good quality but the shaft is not flexible as it should be. I bought it to drill at a 90 Deg in walls. It works great as an extension as it is rigid and well made. It’s not a cheap Offshore replica.

I was expecting it to be more flexible but not It just cost to much

Used as needed to fit some extra lights and have a older house. That's means beams and drywall is lower so no empty space. Uses this to get and angle to drill through the beam. Has some bend. But personally would want more of a bend
