The blade is a 6 1/2 Avanti...... 40 tooth I think.
I used it because it was labeled to endure the most RPM's, its rated for 10,000
The grinder does 14,000 which is why it's run thru a speed control. I put an aluminum blade guard on it but still, if someone just walked in & fired it up, it could get hairy, which is why I stress "dont try this at home"
That particular blade looks to do a 4x4 piece of wood & I made the linear slides over 2 feet long so in theory it will do a sizable musky plug (havn't tried it yet)
I agree there would be more maintenance with a ball tip router bit, but Im having some issues with the grinder bogging down near the tail & a router (1-3 hp) wouldn't have that problem, but I could always upgrade to a table saw motor & throw a 10 or 12" blade on there.
(I actually think thats how Lee Sissons machines run)
