Where do I find Raptor?
Assuming this is thin MDF you should also use a downcut spiral router bit. An upcut spiral bit would pull each sheet upward as it plunges and end up spreading dust between the layers resulting in chip out at the hole edges.
Depending on the thickness and how much vacuum you have not much. When we move MDF with our vacuum lift it will pick up 2 sheets of .75 MDF
Thanks for all the information!
I would be very wary of using a downcut bit for drilling to any depth, as I have heard of fires starting that way.
That's a great point on fire potential on a down cut spiral drilling procedure. With a fast plunge and 3 layers of 1/4"thick MDF I would think it should be alright. However if there aren't too many holes then a safe alternative procedure would be tdo the full depth in 2 plunges about 3/8" each. While some dust will remain in the hole it the shallow depths per pass should further alleviate the potential for fire.
Thanks for bringing that up. It's something I should have touched on in my earlier post.
If you can rout the hole with a slightly smaller diameter bit using a spiral plunge instead of drilling with a straight plunge you might get better results and less likelihood of burning
