Disston Screwdigger No.8 2.5 5 2 2
has it's faults I have been using this for about seven years and would agree with the first review about the grub screw, after the first drill broke (replacements not available from SF as they are imperial 7/64) i now grind a flat on the drill bit so that the grub screw has something to tighten to, a round bit was never going to be any good for tightening to. The idea is good but as with a lot of things they are not thought through or tested in real use. 30 May 2013
Disston Screwdigger Started out working well but as soon as the pilot broke the grub screw would not tighten enough to hold the new one. This rendered the tool useless. 2 Oct 2011
