Erbauer Flat Wood Bit Extension 300mm
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.

Great idea which enables you to use your existing wood bits to extend them get into awkward spaces

Very handy when going through large wood sections. I used it to open 32mm holes in a new log cabin. Only thing to watch is to make sure the two grub screws are aligned correctly with the shaft of the flat fit else you might strip the thread and have to get a new one
