I got this instead of buying a long flat bit, which I may never use again. With this extension, I can use it with any my flat bits which are bigger than 16mm. As it's a 1/4" hex., you could use it with screwdriver bits or anything else that size. A very useful addition to every toolbox.

It did all I expected of it, gave me the extra length needed, was firm and felt safe drilling a blind hole. It comes complete with allen key to tighten the 2 screws. I am well pleased with my purchase. Marked the reliability down as I have only used it twice, but it does feel quality.

Excellent extension bar to reach those hard to get places with the hole saw - fitted perfectly with my small holesaws with a 10mm arbor. Note, this bar won't fit the 13mm arbor.
