key trimming bit

[David Love]

Have you tried going in each direction?  Typically, one direction will chip
and the other one won't.  I believe you want the bit turning in toward the
wood not out away from it.

Subject: key trimming bit

Hi all

I am using a Spurlock style set up to trim my keytops and am having trouble
with the plastic chipping out on the notch cutting station. I am using a 1/2
inch spiral carbide up cut bit from McMaster Carr (27395A31). Is there a
better router bit I can be using here?
