“Bought to add to the capabilities of my juice xe6 and rebar tools. Useful to have but has to sit in a pocket as the holder will not fit in a leather sheath and to separate bits would lead to losing small items. Quality is good but the bits are of a flattened design I.e. only two points of contact on Allen type heads., works but not ideal. The bit holder will take standard bits but is a bit deep so the working head only just pokes out, using longer bits works just fine. I am happy with this item as I got it on sale for half price, I would not have paid full price for it !.”
