Eagle Tool US ESP50072 Flex Shank Installer Drill Bit, Screw Point, 1/2-Inch by 72-Inch, 3/16-Inch Shank,Made in The USA

Good quality, made running cables through floor board a breeze

Saved the day. Split level I needed to get under the floor from about 5' from the laundry room (no ceiling). Drilled through two 2×12 joists and through the floor from the upstairs cable outlet hole, and using a cheap endoscope I got here on Amazon managed to pull a string and then a Cat6 ethernet cable.Only downside was having to cut the cable clip protector off as the hole was too small for a molded ethernet connector. If you are running ethernet, I would recommend the next larger 3/4 size.They recommend a two handle drill, I used a regular drill. Hold it tight and use a medium high speed. Too slow and it gets stuck. It is rather stiff, didn't bend to follow the wall as the video showed, but an angled hole works as well.

First of all let me comment on the fast delivery- I ordered it on Wednesday and it arrived on Friday! I’ve already used the bit and it worked perfect- quality product Made in the USA! I will be ordering again!

Worked well for burrowing wire under a sidewalk

Would have liked more flexibility but went through two two by fours no problem

The build quality is good, but the bit has a design issue. The shaft is round so the bit slips in the drill chuck. The shaft is flexible to allow good reach when drilling.

Application of this item is to drill up through a fire break inside the wall, then fish a 14/2 Romex cable up 7 feet to install in-wall speakers. After using a stud finder and ball magnet to locate the studs and drywall nails (added touch), I then removed the electrical outlet and drilled two 9/16 in holes on the side of the electrical outlet housing. These were my entry points for both the 54" 9/16 flex bit and my Rigid inspection camera to see what I was drilling into behind the wall. I was a little nervous applying force to get the bit to bend. Eventually, I gain more confidence and was able to apply pretty good flex and got it to drill upward into the fire block. I did run into an issue with the insulation. The bit got tied up a bit, when I was drilling - twisting insulation around it. No problem though. Just removed some of it at the top where my speaker cut-out is and replaced some insulation later. On the second speaker, I ended snapping the bit! Yes, as the disclaimer states, there is a breaking point. Well I know that is now:-) It was a lot of force and a very aggressive bend that caused it. I ordered another one today to complete the work. Luckily the bit broke with about two feet of it outside the outlet. I'll be able to remove it and start over with the replacement.

I am NOT a pro electrician, but routinely post-add lighting and wiring in houses I remodel. This has made a massive change in how easy it is to run additional wires for outlets or light fixtures. Great quality and flexibility. Super easy to use. It has a very small hole at the end of the shaft to add a wire through and then pull your wiring through after the hole(s) have been cut. Great addition to the remodeling toolbox.It takes a bit to run it straight across multiple joists, but can be done by flexing it.

I've used this drill bit to do a "new work" electrical outbox for coax cable and outlet and to drill joists for the same cable. I drilled around 15 holes in total.Overall, I'm pleased with the quality and drilling speed of the product. The drill bit wasn't as flexible as I expected but this is my first one so I guess my expectations were a bit off. I found it extremely useful to drill joists if you have a hard time to fit your drill with a standard drill bit or you have different objects (e.g. air duct, electrical wires) in a way.

Worked for what I needed it for, good sharp drill bit. The rod itself is not that flexible but I just needed it to drill down through the bottom of a stud wall through an opening for an electrical socket to feed the cable through, twice, and it worked perfect. Never know when I might need it again, or friends/family to borrow.

We use those everyday in houses to get new wires in wall, very good product, it is also not expensive for this kind of tool!We resharpen them once or twice before they are dead. If you never hit nails they will last very long but the reality is that you will get nails or worse a screw. I did contact their support for 2 questions before re-buying and they told me some nice answer that I would like to share here:What is the real difference between the Auger and the ScrewPoint? We usually drill going up in 1.5 to 3in of wood.We also sadly hits nails from time to time so do one perform better if you happened to hit a nail? We usually hit it then try again somewhere else.The ESP was the first design for a cable bit by the inventor many years ago. Most people are more familiar with an auger style bit and this is where the EA came from.ESP cuts a bit faster and the EA leaves a cleaner hole. That is the only difference I see.Nails are a problem, all of the cable bits are manufactured using 4340 and heat treated to 53 to 58 Rockwell. We do not make them any harder because they are mounted on long spring steel shanks and the torque involved in cutting through steel can cause the shank to snap and could cause serious injury. We would rather you sharpen the bit than be injured.hope this help! 10/10

I tested this on my test rig and it works as expected. The flex of the rod is not bad.

The product itself is top notch. It is definitely stiff and doesn't have a lot of flex, but that's expected with the 36" model, as noted in the product video. But it drilled through studs like a champ, with nice clean holes that made pulling wires through a breeze.The one problem I have is that I was sent a product that was clearly used before. The label was ripped off the shaft and scratches all over it. Even the paint was chipped off the blade. The box had been clearly closed back up with scotch tape. So pretty unimpressed that I paid full price for an open box/used version that should have been marked as such and sold at a discount.
