Hey Peter and greetings,
Good news mate, I got a email back from black & Decker and they do sell collets for the KW850E and they are as follows: 588538.00 = 6mm
588539.00 = 6.35mm
588543.00 = 8mm
If anyone needs it their free help line Australia is 1800 654 155 between 8 am - 4.30 pm Mon to Fri
I think my router would of had a 1/4" collet with it as well, I did buy it new, but I've no idea where it is so I'll buy one. I am thinking of buying another router and leaving this one for my Triton Table. So I may as well look around and get one @ 1/2" shaft size.This may give me a better range of bits. (not sure till I look )
Thank you for your reply and thanks for looking on the net for information for me.
