Erbauer Flat Wood Bit Extension 300mm is rated 4.5 out of 5 by 29.
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.

Rated 5 out of 5 by from Cheap easy to fit and use So easy to use and made job quicker. Use this saves you buying loads of separate 300mm drill bits, use this to extend them all!

Rated 5 out of 5 by from Worked Well 5***** Just tighten up the allen screws on the flat bit and away you go. Straight through the joist/block/cavity/block and another joist with a long bit. Also comes with the required allen key

Rated 5 out of 5 by from Reaches the parts other bits.. Needed to drill an access hole for a lighting wire through a joist but without access from either the floor above or ceiling below. Using this extender combined with the Armeg Wood Beaver drill bit bought at the same time I was able to drill a smallish hole (easily filled with a bit of filler afterwards) through the ceiling board and the joist at an acute angle such that I could get cabling rods through to my light fitting spur on the other side. Without this extender I was at a loss for what to do without trashing either the floor above or ceiling below. It holds the hex bits really firmly and those Wood Beaver bits really get on with their job so take it very easy on the drill speed and be sure to check both sides of the joist for pipes and wires with pilot holes and suitable probe. This thing will live in my drill case which at 300mm, fits just right with my DeWalt. It's well engineered from a single piece of quality steel and held on tight to a drill bit that wanted to drill to the centre of the earth given half a chance! The bit is held good and straight.

Rated 2 out of 5 by from Grub screws kept coming undone The idea to enable me to use the drill bits at full length using the extension arm was a great idea but, the grub screws kept coming loose all the time. From the start the Allen key was found to be a very loose fitting in the grub screws, I tried various other keys that I had but none fitted the screws. After having tightened the screws hard to stop them coming undone again I found that the key would only turn in the screw and I had to drill out the grub screw to get the drill bit out. I will now recut the thread and put in some better quality grub screws that will fit the Allen key.

Rated 2 out of 5 by from Handy but doesn't last I think these can be useful for limited use as do work but are not sturdy enough. Grub screws go all the time have had many & same case every time. Sometimes with only drilling 2 - 3 holes. Purchase the one piece 300mm extension spade bits work out much better value for money as they last much longer.
