Eagle Tool US ESP75072 Flex Shank Installer Drill Bit, Screw Point, 3/4-Inch by 72-Inch, 1/4-Inch Shank,Made in The USA

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.

used for install wires for the recessed lights, easy to use

I somehow got this thing stuck in a wall structure and was putting my whole weight on it and had to use extreme torque with finally using a sledge to finally pull it out. The thing was not bent or damaged in the least. Very sharp and worked great. Highly recommend.

I had use it just a couple times and now it takes forever to drill a hole

This product allowed me to drill a hole that would have been very hard to reach in order to wire an outdoor outlet. If you are getting this as a super-extended drill bit to go through wood or other soft material, it works like a charm. However, it is quite rigid and does not hardly flex at all. I would not purchase it for that feature.

I tried this drill for the first time installing pendulum lights over a kitchen island and while it worked great, i wish there had been some instructions. Never having used one, I had to figure out the hard way what not to do. The process is this.Make your holes for the can lights after laying out the locations. I used a multi-axis laser.Figure out where your joists or trusses are and then feed the drill bit through the hole in the direction of the next hole location based on whether there's a truss in the way.The self drilling aspect will pull the bit through and once through the joist keep pushing the bit in until you see it in the next hole.Attach a pull wire through the hole at the auger end of the bit and bend it so it doesn't pull out. Pull slowly and twist the bit back and forth until you've got the drill bit back out of the hole you placed it in to start.Unhook the wire from the bit and attach your Romex to the pull wire that you just fed through.

If you require any tough drilling, this is not the bit for you. I have been through 3 of these...call me the fool for giving this product this many tries. I rewired a 1950's house and needed the 72 inch bit to get through the base plate from the switch through two layers of 2x4 fireblock. The wood in the house is old and dense...not like the new pulp wood 2x4 studs of today. At first I thought I was hitting nails and damaging the bit...not surprising. On the third bit, I took it out of the package, set it up to drill and it was barely making any progress. I decided to drill from under the house using a 7 inch diablo bit and it chewed through it like butter...ok, something wrong with this bit. So my electrician put more pressure on it from above and ended up shearing off 12 inches of the shaft. Is this really made in America with high quality steel? I'm not so sure. Lesson? Maybe I should find a better quality bit. Up to you...if you are drilling through new soft pine studs and don't hit a nail, this bit should do the job. If you are going to challenge this thing in any way, perhaps a better quality bit would be wiser. I've spent over $100 on three bits that are trashed. Frustrating.

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.

54" pour les interrupteurs ok .Mais pour les prise de courant jusqu'au plafond avec une tige extension de 36" pas assez précis . Et surtout pas avec de la laine isolante dans le mur. Fait de belle barbe a papa avec votre laine.

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

Not flexible enough.

Doesn’t flex
