What size dado should be used with a 1.5 HP (120V) Delta Profession Table
Saw? Is the power adequate for an 8" dado set or should a 6" set be used?
Does anyone have experience using an 8" dado set with a 1.5 HP Contractor
saw? What are the CONS of such a setup?
When I bought my dado at a show, the owner of the company, Ridge Carbide
Tool, told me to get the 8". He said the 6" is for the smaller benchtop
type saws and any 1 1/2 HP can handle the 8". I've used mine for oak
plywood, MDF and solid wood with no problem.
You do have to slow the feed rate for deep cuts if you are taking a wide
cut. Removing 3/4" of material takes a bit more than a normal blade kerf.
My first saw was a BT-3000. I got a 6" dado blade for it because there
wasn't clearance inside the dust collection shroud for an 8" one (yes, I
know some people say it can be done).
I had never actually run into anything I couldn't do with the 6" dado
blade, but when I upgraded to a unisaw, I went out and bought an 8" set
anyway. Funny thing is that now I more often than not just use the 6"
set, and the 8" one sits on the shelf. I find the smaller blades easier
to maneuver on and off the arbor without banging the teeth into metal
Can't speak directly for the Delta but an 8" works fine on my 1.5 HP
Craftsman RAS on everything I've tried it on--haven't set it for max width
and gone after a piece of Ipe yet but even there the worst that's likely is
that it would be necessary to make multiple passes.
The only real con I see is cost.
