Hi guys I need some of your collective wisdom applied to a bit of a problem I'm having here.
I have a Grizzly G7946 1/2 HP 110V floor radial drill press that I use amongst other things for drilling counter-bored 1.5" / .75" holes in wood stock from each side of small (4-6" tall, 2-4" wide) square stock for game calls and other projects and I'm having some problems drilling the larger hole. In most woods I manage just fine but in some harder woods (Purpleheart, Osage Orange, etc) the forstner bit is binding up and stalling the motor at the lightest cut. I'm drilling these into the end-grain and I know that makes it harder but again like I said it works great with the exception of some denser woods. My bits are sharp as sharp can be and I get the same result with generic HSS ones, my Colt Maxicut ones and my Rockler Carbide tipped ones.
So my question is what do you think my problem is here and what do you think a solution might be? Is it simply that my Grizzly doesn't have the power to drive these bits through this dense wood? Should I upgrade to a more powerful drill press? If so which one?
Thanks in advance!
