Cutting fiberglass

[foamman]

Hey everyone,
Does anyone have any data (speeds and feeds) on cutting fiberglass? I plan on using a 67-101 diamond pattern bit.

The fiberglass is .125 inch thick. MCmaster-Carr structural fiberglass. Barcol 40-45 hardness.

Thanks in advance

Ben

I don't know about cutting it on the bot but I have cut a lot of it with a hand held router. Wear a tyvek suit and a good full face respirator to protect your eyes and lungs. I had to do this in the summer when the room I was in was about 100%. It eats bits also just remember the glass in fiberglass has silica and dulls bits real fast.
