Penultimate

I'm trying to make a pen body from clear extruded acrylic and it cracked while drilling. I had 0.5 inch diameter rod in my collet chuck drilled progressively larger holes with lube to .360 ID. I got a bunch of stress cracks.
Any advice on drilling? Do I need a different material?
Thanks.
