Rated 5 out of 5 by from Great for those noggins I bought three of these combined with a long wood bit to get through a noggin halfway down a partition wall. Thing to remember is to allow for the overlap. So with all four bits combined my overall length was approx. 112cm. I recommend gaffer tape on the joins if you're drilling down from the top. You don't want any vibration loosening the grub screws and the whole thing dropping down inside your wall!

Rated 2 out of 5 by from Disappointing,lost grub screw Bought this extension bit to help with first fixing. First hole I attempted to drill ended with a grub screw falling out, never to be seen again. I made sure the screws were done up tightly prior to drilling but unfortunately one fell out. Could just about drill holes with one grub screw securing the flat bit. But had to re-tighten multiple times, as the bit did spin in the extension. Might be worth opting for a more expensive bit extension that doesn't require

Rated 1 out of 5 by from ABSOLUTELY USELESS Didn't even get through one joist with this. The grub screws stripped my Bosch flat wood bit. Don't see why the holder isn't simply hexed and magnetised as this would solve the problem. Brand new item now in the bin.

Rated 4 out of 5 by from Just the ticket Needed to extend a longer extension to reach the next stud in a wall having drilled through the first one. Fitted this extender into the other extension, then the bit and was able the bore a hole to feed the electric cables to the new switch position. Perfect.

Rated 4 out of 5 by from Fixing Spurs Used this extension to cut holes into a wooden post through a concrete spur. Used a standard 16mm flat wood bit. Worked well. Reliability to be checked.

Rated 5 out of 5 by from Trade quality at DIY price I have used a few like this over the years but this one is the longest and strongest of them all; with strong grub screws to bolt the hex flatbit in place. It's possible to double these up for even longer jobs and as a tip I always re-sharpen flatbits with an angle grinder to extend their life and so that they cut easily and cleanly.
