22mm or 7/8'' flat bit? I've just measured two of mine with a micrometer and found that my old 7/8'' is within 2 thousandths of an inch of the stated size (0.873'' or 22.17mm) whereas my 'modern' 22mm flatbit is 0.885'' or 22.48mm. This could be fortutious, poorer machining accuracy or deliberate oversizing of the '22mm' bit (?), but would seem to indicate that 22mm is indeed preferable to 7/8''
25mm Irwin blue groove. never had a problem.
25mm auger/ irwin blue depending on the door.
if its a cheap latch, and they tend to be the under sized ones, the job is probably cheap. so a little filler is no worries.
if the job is a quality one, the latch tends to be good.
ta and indeed da!
Why don't manufacturers make them so they fit first time? MI's usually state to use a 22mm bit.
I particularly hate the sort that do fit first time, then when you put the handles on, you find that the gubbins of the latch is sticking. Take the latch out again and reach for the 1/4" chisel. Grrrrrrrrrrrrrrr
How hard is it for manufacturers to make them bl00dy well fit the hole they specify?
i know what you mean! cant remember the makers name, its the ones with 'this way up' on them that are the worst. why on earth have a moving part outside the barrel???
i have either used 24mm or chisel out rest
Dude! What was this? can you remember?
Aah! Come on! Theres no need for that
