i HAVE A TRITON ROUTER THAT TAKES 12.7mm ROUTER BITS WHICH IS SUPPOSED TO BE EQUIVALENT TO 1/2" ROUTER BITS. HOWEVER THE 1/2" BITS ARE LOOSE IN THE TRITON. WHY IS THIS?
It sounds as if you may have been supplied with a 12mm collet instead of a 1/2"(12.7mm) one. Unless you've got a 12mm shank bit, or more likely a 12mm shank drill, to use as a gauge, it may not be easy to tell.I have the same problem except the other way round,the trend 1/2" bit I bought is to tight in the triton collet!
