Milwaukee 48-28-1010 6-Inch-by-1/4-Inch All Hex Extension

I have been using this extension in my drill driver for a while now and holds power bits really well without much of any wiggle or play of the bit. They seem to be have a strong build to them and the mechanism to hold the bit works pretty smooth. I also have the Irwin lock-n-load bit extensions and they don't seem to hold the bit as tight as the Milwaukee.

I have used this tool to extend the reach of my impact drivers into areas that were to confined for the actual tool to reach. It was most useful while replacing windows in my house. The new vinyl replacement windows came with screws that needed to be placed inside the frames at the corners very close to the glass. Without an extension the diameter of the impact drivers and the short reach of the bits created an excessive entry angle for the screws. Using this extension allowed me to reduce the entry angle a significant amount without having to resort to more expensive options such as right angle drives or flex drives.

It's one thing to be able to extend the reach of a hex driven bit with something that holds it firmly. It's another to also be able to quickly change it out without the chuck jamming up. So this is the only brand I've found that can do both reliably.
