Greycore Tools Installer Drill Bits are the ultimate tool to pull wire through the wall or floor when space is limited. Fish eye holes on both ends of the bit enable wire pulls from either direction.

Didn't break, worked fine with my Milwaukee M18. Good value.

Well built. Flexible as needed. Came in a box as tall as the bit and 2' wide, but it did make it undamaged.

You get what you pay for right, this thing broke as soon as I attached it to the drill and tried using it. I bought a $70 one from Home Depot like I should have all along and it works great. Do not waste your money on this cheap thing.

I have a tv mounting company and needed this for running cable through walls with fire blocks. I was hesitant to pull the trigger after reading mixed reviews. Nevertheless, I bought it and was perfect. It’s sturdy and has some flexibility as well. I would say if you’re needing to bend a right angle then it’s not that flexible. Be sure to select the 54inch as the 18inch isn’t flexible. For extra help there a YouTube video titled “Labor Saving Devices Bell Hanger Bit Fireblock How-To Video” it was big help.

This drill bit is extremely flexible and really easy to use. I was able to get a new hole through the bottom plate of a 2x4 wall through an existing hole for a single gang box. I will definitely be using this again in the near future to retrofit CAT6 throughout my house.I will also be ordering the 3/4" bit.

Sharp bit, self-feeding auger works great. Flexible. Just sued briefly so far, so no info on durability.

I used this to get landscape low voltage wire underneath our walkway leading up to our house so we could have lighting on both sides of the front of our house. Was very easy to use. I use a larger gauge wire that would fit in the spot to pull the wire through on the drill bit, so I just used some electrical tape to tape the wire to the bit to pull it through without issue.
