Sometimes you need to drill through walls for wiring access. Phone, cable TV, and internet use, all require their own access point. Most drill bits won't reach. This gadget does a beautiful job. It's solid steel and feels heavy. The allen wrench does a good job of holding the bit solidly, too.

One small problem; the head of the extension is about 5\8 of an inch in diameter, and the two small set screws will typically project another 1\16 of an inch, or so. This sets a limit on how small a hole you can make with a full reach. Still, I consider this extension a must-have in a drill kit. Very solidly made, should last forever. Quick delivery, too.

5.0 out of 5 stars Great!, July 25, 2010

I purchased this drill bit extension from Amazon because all of the local places did not carry anything that would hold a 1/4" shank. The quality is excellent and I have able to use this in conjunction with different sanding flap wheels.
