Like some other reviews I was skeptical at first. Bottom line is that it works. I had to use every last inch for the job I did running wire though my basement ceiling joists. The bit gives very little clearance but I was able to pull Simpull brand 14/2. The trick for me was stripping back the black and white wire and looping the ground though the hole in the back of the bit and then pull from bit end (front) out. Worked like a charm. I did try to pull it from the back as the bit end also has a hole but getting the bulbus head back out the way it came kept getting hung up. Like I said, it has very little clearance, but it works. Also be sure to set the bit so it doesn't curve up or you may end up boring a hole into the floor above. Its good to have someone help you with that part but once you get it started its a one man/women job. If you aren't handy you should probably not try this on your own. :)

I used the 1/2†for running CAT6 Ethernet cable. Because it was a short run I purchased cable with the ends already attached. The 1/2†hole was just a tad too small so I had to use a 5/8†bore to widen the hole. I think this would be the perfect size for running bare cable.This bit was very flexible, took little effort to get it started in the wood and did not bounce around in the wall. I was able to drill a hole, straight down, through a single outlet sized opening 10 inches above the floor using about a 90 degree bend in the flex shaft with no issues. I did drill all the holes next to a stud so that helped stabilize the bit inside the wall.I used a Makita 18v cordless drill and would rate myself as average when it comes to home repairs. This was my first experience using a flexible bit of any size.

Using this bit requires a little bit of skill. You REALLY need to make sure it's hitting vertically inside the wall. I got my first one stuck in the side of my house. I had used it about 20 times before with no issue, but I got a little too cocky on that last one. Its still in my wall, I had to cut off the shaft because I couldn't get it unstuck. I bought a new bit and have been more cautious with how I drill, works wonders for running low voltage lines in finished walls.

I have used many long drill bits in years of old building maintenance and rebuilds. Typically used so one does not have to open up a wall to access the space to run electrical wiring. This method does require adequate clearance for the long drill bit.The problem with this and other long drill bits is the shaft is a smaller diameter than the bit. Numerous reasons for this that I won't go into. With a 1/4 inch diameter shaft driving a 1/2 inch diameter drill bit the small diameter shaft will begin to wind up (twist) as the material that the drill bit is cutting gets harder and requires more torque to the drill bit. There is a point at which the material that the drill bit is boring is too hard. At tis point the smaller diameter shaft will wind up and if the drill motor continues to apply torque the shaft will twist and break off. Be aware of the shaft wind up as you apply pressure to the drill bit and be sure the bit is sharp.

I do a lot of wall fishing, this bit has seen about 400 holes and is still punching through studs and floorboards like it did on day one. The screw tip bites in so it doesn’t roam around the stud bay, but unlike a Klein it doesn’t bite in so hard it tries to throw the drill through the drywall, into the customer’s bathroom, through the tile, and finally coming to a rest in the neighbors Tesla door.My Makita is a notorious flex bit killer, the old girl has mangled about 10 flex bits in a calendar year, and will straight up snap the head clean off the shank (RIP Milwaukee flex bit, you belong to the house now) but this bad boy has held up to the teal terror for many moons.

Easy to use. I should have ordered a larger 3/4 bit instead of the 1/2 " as I changed my mind about feeding two strands of CAT 6 which is difficult to feed through a 3/4" hole. But the product works. Watch some Youtube videos to get an idea on how to use. It is also helpful to have a 2nd person to guide the bit into the hole and centered.

I used this drill to bore a hole through packed-in soil in a PVC pipe that was inserted under a concrete walkway. I blasted out as much soil as I could with a high pressure washer but the last foot of pipe had very dense soil in it.This drill easily cut through that soil. My intension was to use the tip to attach cable to it and pull it through but there is no hole in the drill bit tip, so I fed fish tape through the hole in the soil, taped the cable end to it, and pulled it through the pipe.

I used this product successfully three times. The rod snapped on me during the fourth use. I paid $45 for the product, so that's $15 per use... a little too high.The fourth time I used the drill bit, I was drilling through 3.75" of wood rather than the 1.75" that you'd normally drill through in the wall.Sorry I didn't grab a picture of the break... the rod snapped just below the drill bit head. The head of the bit will forever be a part of the wall now.
