Is Lexan a cast plastic? If not which is the best plastic to carve. ---

Lexan is a trade name for polycarbonate. It can be machined according to specs. Polycarb sheets are extruded. Cast acrylic machines great. I have used both but with extruded sheet, I will usually use a coolant; small pieces, I’ll jus shoot some windex on the sheet every now and then. ---

I just finished a job using 0.188" Lexan - templates for a woodworking tool. I used a 1/8" 2-flute end mill, DOC of 0.03". 19,000rpm (3 on the 611), and feed rate of 20ipm. I got nice, clean chips, no burning, no dust. Due to the nature of its use, it had to be polycarbonate for its toughness. I tested at higher feed rates but wasn’t getting as clean a cut as I wanted. ![](https://canada1.discourse-cdn.com/flex009/uploads/inventables/original/2X/5/5c851159444e016641238aa6f0b75646ded51979.jpg) ---

That looks great Bill. What bit did you use to countersink the holes? ---

> [@JasonHughes](#): > > That looks great Bill. What bit did you use to countersink the holes? I set up two pocket cuts; one for the countersink that is 11/32" diameter and 0.078" deep ; the through hole is 11/64" diameter and cuts to 1/8" deep. I used a 1/8" 2-flute bit for all cuts.
