Polycrystalline Diamond vs. Carbide alone

[ATX Poly Products]

Hi Guys,

I have been doing some composite panel work "brand name Glastik".

They are red insulating boards for arc chutes and such for Tolley cars that are going to San Francisco.

My question is How does Onsruds Polycrystalline Diamond routers fair compared to the 2 flute Atrax upcut carbide regular center cutting end mills I've been using. I am getting awesome edge quality but somewhat short bit life do to the glass in the panels. I am running at .5 IPS at 10K...

Thanks
