Eagle Tool USEA37536 Flex Shank Installer Drill Bit, Auger Style, 3/8-Inch by 36-Inch, Made in The USA

It is a great tool to have. Used it to run a cable through a noggin in a stud wall. I drilled an access hole in the plasterboard and used a cheap endoscope camera to see what I was doing. Found that you need about 10cm height of the hole to get enough angle so the bit hits the middle of the noggin rather than the plasterboard wall because it's not hugely flexible - what I did was cut a 1cm wide channel up/down from the access hole to create the angle for the flex bit to go in. Use the camera to spot where you want it and away you go. Short sharp bursts using the power drill and reversing to clear the bit if it gets stuck is the key. Got through in about 10-15 seconds of drilling.

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.

Much less bendy than expected, it’s pretty much solid just long with only a few mm of flex

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 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.

War bei dem ersten Versuch erstaunt wie gut der Bohrer funktionierte. Aber nachdem ich die zweite Bohrung in KieferVollholz gemacht habe ist der Bohrer direkt abgebrochen. Kann daher leider keine Empfehlung aussprechen.

I was expecting it to be more flexible but notIt just cost to much

This was the perfect tool for the job! It worked even better than I had expected!
