V-bit for cast acrylic?

[jkaras]

Hello, I am milling some 1/4" deep v grooves into some clear cast acrylic on my Shopbot PRS Alpha. I have been using an Onsrud 37-82 (60 degree bit) that came with the machine. It is working good, but the tip is chipped and I was going to get a new one. I looked up this bit and it says its for hardwood and plywood. It worked okay for the few tests I did, but now I have a large production to run and I was going to buy a new one. Is there any recommendations for 60degree v-bit specifically designed for cast acrylic or hard plastics? Onsrud does not seem to have any... Thanks!

We cut a lot of corain which is 100% acrylic, and just switch from cheap v bits to a v bit made by Vortex tools that is made for solid surface and it works fantastic but they cost so coin.

What speed setting are you using those bits and have you used 90 degree bits and 60 degree bits.
Thanks Doug

We cut at 1.6 ips (xy) .8 ips (z) RPM at about 16000 depth of cut is .0625".
That is with the .25" 90 degree V.
