I just found a Whiteside replacement for the 17/32" 7
degree dovetail bit at http://www.hartvilletool.com . It is
item RD7531. The salesman called Whiteside while I was
waiting and they said they are not yet making the 11/32
straight bit, but with more requests they would. Hartsville
has a 15% off sale on router bits this month. The 17/32" is
$15.29. Woodcraft also carries them for $21.99 and a two bit
set (dovetail and straight) for 34.98.
Whiteside #146433 is the 17/32".
