What Customers Are Saying
Customers overwhelmingly praise this drill bit extender for its secure bit retention, reliability, and ability to reach difficult drilling locations. The dual set screws firmly lock bits in place, preventing slipping during impact driving or deep drilling up to ten inches or more. Reviewers highlight its effectiveness in previously inaccessible areas—through thick walls, concrete, and multi-layered materials—with many using multiple extenders end-to-end to achieve five-foot lengths. The sturdy, balanced construction resists twisting under load, and the beveled back end aids tool removal. A few users report occasional set screw issues, but most consider this an indispensable solution for challenging installations.

Would RecommendThis is great for getting into tight spots, the allen wrenches tighteners are not very convenient if you need to switch bits

Would RecommendNeeded narrow shaft/connection for drilling deeper hole.
Verified Purchaser
extention to large for bit
Would Not Recommendto use this extension your drill bit needs to be fairly large, 1/2-inx6in is to small to fit the connector bit into the drilled hole.

Drill bit extender for those LONG reaches
Would RecommendNothing bad to say. Needed a longer extension to get through a 2' wall. Worked like a charm. Very secure.
Verified Purchaser
Works great!
Would RecommendThis extension works well for a couple of reasons. 1st, it attaches with two hex set screws that work well compared to the usual clip on type. 2nd, there is a bevel on back, or closest to the drill, if you are drilling a deep hole and allows for easier backing out the extension. I drilled an 8' hole through a log wall and would not have been able to do that if not for multiple of these extensions. You will have to drill at least a 3/4" hole with this extension for it to work unelss you just need...

Great for extendeing length of bit.
Would RecommendEasy to use. Needed to extend a bit by 3ft to reach the wall in an overhang. Put 3 of these bad boys together plus the bit. Made easy work cutting a guide hole to get access to from the other side.
