Rated 3.7 out of 5 by 3 reviewers.
Rated 1.0 out of 5.0 by Expensive garbage QFirst and only One time use , drilled only 1.5 inch into wood and got stuck, soon afterward it broke one half inch from the drill side end where there is a hole for cable feed. Good idea, poor blade design and inferior material grade. Spend Half the cost on the drill bit extender to attach the flat blades that cut much better May 16, 2012
Rated 5.0 out of 5.0 by outstanding placed inside wall through new box hole to drill up through double top plates to install new wiring. excellent in every way: cut through wood like hot knife through butter, has hole to attach wire and pull back down. flexible yet very sturdy. January 24, 2012
Rated 5.0 out of 5.0 by Must have for pulling wires! I have been using this drill (and an older discontinued combo drill) for several years and I cannot begin to tell you how much time and work it has saved me. I have used it to install electrical, phone, cable and network lines on both first and second floors. You will need 2 extensions to do the second floor. Have not found them online but they are in the store. The best thing about this drill bit is that once you finish drilling the hole you can use it as a snake to pull the wires up. The drill has a hole at the tip of the bit so you can attach either the wire or a pull grip to it. Then you just pull the bit and the attached wire back up through the hole you just drilled. I would recommend getting the Flex bit placement tool (to make sure it is centered in the wall) and a pull grip for best results. Also make sure the drill you use has the torque locked and has enough power to drive the bit. 12 volt or higher cordless (what I use) should work. You may find you want to add more outlets once you see how easy this makes it. I know my friends and relatives did. Just find where you want the outlet, cut hole for box, put drill in the hole drill to basement, go attach wire to drill, pull drill and wire out of hole. Then just install outlet. I read one review on another size of this drill that said the head came off in 15 minutes. I have never had a problem with the heads coming off. I have had to sharpen the old combo bit a few times but I have been using it for over 10 years. I hope this helps! Thank You. September 24, 2011
