Erbauer Flat Wood Bit Extension 300mm is rated 4.2 out of 5 by 35.
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.

Rated 5 out of 5 by from Did the job well Needed this to add lights to decorative sleepers round garden - standard drill bit was too short, when attached to this it done the job. Allen Screws are a bit fiddly but gets the job done.

Rated 2 out of 5 by from Never Again Cost me an expensive Bosch wood bit. Grub screws don't hold the bit in place. It ended up spinning round and ruining a good drill bit.

Rated 1 out of 5 by from waste of time and money Screws kept coming loose every other second. Had to stop to tighten them until one of them snapped. Couldn't finish the job with this product.

Rated 1 out of 5 by from flat wood extension bit let down by the shoddy allen key(it stripped when I tried to tighten grub screws)supplied..

Rated 5 out of 5 by from Great value extension This extension bit worked perfectly for drilling through the gate posts for field type gate hinges. Strong enough with good sized grub screws to hold the bit. When drilling pull the bit out of the hole regularly to avoid build up of wood shavings as they get trapped on the wider part where the bit fixes to the extension.

Rated 1 out of 5 by from Waste of money Allen key supplied was poor fit so tightened with my own but it still kept coming loose on the drill bit. Now just another piece of junk in the scrap box.
