OK, OK, I know, I shouldn't have bought a cheapo, no-name Router, and I suspect my "Matrix" (Germany) 1200 Watt Router is actually a(nother) bit of badge engineering! Nevertheless at just 10% (really) of the cost of a Festool, it had to be worth a punt, I thought .....
The bit shaft dia which this Router collet accepts is 12 mm according to the spec sheet, and the bits that came with the Router kit do all have a nominal shaft dia of 12 mm (actually a whisker less, as you'd expect).
My issue is that the collet does not appear to open up far enough to accept half inch (12.7 mm) bit shafts - the internal "gripping vice" of the collet appears (repeat appears) to locate into a groove machined within the "upper" inner face of the outer "nut" and no way will that groove allow the chuck to open far enough to accept a 12.7 mm shaft.
I know little about Router collets but with "normal engineering" collet chucks (as used on an engineering lathe for example) it is quite normal for any particular size of collet to have a dia range of + 1mm above nominal size, sometimes even a little more. Are Router collet chucks different, or is my Matrix collet either "broken" or NBG?
My reason for asking is that, for example, Wealden have bits with several different diameters within their various ranges but there is NO range with 12 mm dias, just half inch. I now have one of their half inch bits and want to use it in my Matrix Router but as above, it definitely does not seem to fit.
I have been in touch with Matrix via their website, but unsurprisingly, they are of no help at all - I have the feeling that they set up to get someone in China or somewhere to make a gazillion-off of a certain tool, sell 'em all, and then that's it, finito, on to some other tool.
So I've been looking at other Routers in retailers here (Dewalt, Bosch, and Festool so far) with my Matrix collet outer nut in my hand to see if any of those collets would be compatible with my Matrix. That way, I could buy a spare collet from one of those ranges and off I'd go. So far no luck, but I have yet to try Metabo, Makita, Trend, and Triton, plus here (Switzerland), there's also AEG - anyone heard of that brand BTW?
Just for info, the thread of the Matrix collet appears to be a nominal 20 mm crest dia x 1.0 mm pitch, 60 degrees, as measured on the main shaft of the machine (i.e. a non-standard Metric thread according to all my tables).
The websites of all the above Router manufacturers show only the bit shaft dia that their collets will accept, not the thread info, so I guess I'm left with wandering around all the retailers trying my collet on their various shafts - UNLESS anyone here can tell me otherwise please???
A final Q if I may, related to the above - all the Router brands I tried here so far (Dewalt, Bosch, and Festool) all have collets marked as 12 mm, NOT as 12.7 mm, and indeed, most of the router bits one sees here are 12 mm (or less), NOT half inch shaft dia. But half inch bits are sometimes available here (and as above, many are available on line from several sources). So do the above collets marked as 12 mm capacity actually expand to accept half inch shafts - in other words, is my problem really just that my Matrix collet is NBG?
Thanks in advance for any pointers - it will be clear from the above that I'm paddling (drowning) in unknown waters here!
Any comments/advice welcomed.
