Hi all,
I was just wondering what is the best type of bit to drill a phenolic router plate, or would a normal carbide tipped bit work well. And is there any special considerations to keep in mind while drilling?

Hi Biker

I just used a standard drill bit, like you get in those sets (nothing fancy). I found that if you first drill through with a small bit, that gives you the pilot hole to work with. Just be careful that the drill bit does not wander (use a sharp punch to start). Take the size drill bit that you want the hole to be and drill through half way on both sides to eliminate any chipping. Use a counter sink or counter bore to allow the head of the screw to sit flush on one side of the plate or a slight bit below. If you use a forstner bit in your drill press, keep a backer board under your plate and that might help the chipping also. I would not use a brad point bit, even though they are excellent, as you might tend to ruin them. I am sure other members will have their own versions of how to attack this also.

Hi italian biker

drilling into phenolic, it's funny stuff to drill, it's not like wood,plastic or metal it comes out in chips,,, I would suggest using stubby machine drill bits..

135° Quick-Cut point will not "walk" or "wander", Special heat treatment, results in cutting edges that remain sharp longer when drilling in tough materials...
