Shank 12.7mm - Collet interior 12mm tight.

The (different) router I have came with both 12 & 12.7mm collets. It was
fitted with the 12 (cue swearing) until I realised they were different, not
just a spare. Has the 12.7mm been lost from the box? The 12mm is no use to
man or beast - never seen a bit that size in my life. Maybe worth a call to
the helpline if that's in the manual, should get a correct one sent out
right away.
