After buying a PC Model 301 trim router and returning after the bit got
stuck to badly it got destroyed during my attempts to remove it, I decided
to follow up on a suggestion that one of you made in reply to my post at the
time, i.e. to use a Dremel Advantage rotary tool (Model 9000) with the above
mentioned plunge router attachment.

According to their web site, it takes 1/4" router bits. However, it does not
specify the size of the opening of the router base. When I called customer
service tonight, I got a big surprise: they stated that using any router bit
other than those manufactured by Dremel would void the warranty!??

I was not planning to use it with very large bits, I have my table-mounted
Bosch for that, but I was thinking that using roundover bits up to 1/4"
would be nice. Also I much prefer carbide over steel, but the Dremel router
bits are only made with steel.

I was wondering if one of you has this attachment, and if (a) the warranty
does indeed say that, (b) what your experience has been --- have you used it
with standard router bits, and (c) what is the size of the opening in the
base?

Thank you in advance for the feedback!
