I need to cut a dado in a hunk of melamine veneered MDF. Trial cut
using my dado set yielded a lot of chip out. Using a zero clearance
insert. Any instruction, tips, hints, to eliminate the the chip out
will be appreciated. TIA and Happy Holidays!!
Well, the tooth *does* exit else it wouldn't be cutting, would it? :)
All you want to do is just cut thru the melamine on the first pass so you'd
need to experiment with the depth since blade teeth vary in size, I find
about a 1/16" depth works well.

I apologize in advance for asking the obvious. Are the outside blades
on your stack on the proper side of the stack?
Reason I ask, I had an issue many moons ago where some simple dados in
decent plywood were tearing out rather badly.
I had the right outside blade on the left etc... That made allll the
difference in the world.
On my Freud stack, the outside blades run just a RCH high relative to
the chippers. They score melamine on PB rather nicely before going for
the full depth. Keep in mind that the stack is very sharp. I only use
120 gram melamine, and that helps too. I get minimal chipping.
On the cheaper melamine boards, use a router.
Upon further reflection, I seem to recall that I have had bad luck
with chipping melamine off MDF regardless of tool used. Long time ago.
