folding dibond past 90 degrees

[tverdin]

I am working on a project that I need to fold dibond aprox 120 degrees. My plan was to buy a 120 degree V bit and problem solved. I am having trouble finding a bit that works for me. I found 1 that was 135 degree (which would be fine) for $40 and i ordered it only to hear back its on back order and would be 6-8 weeks. So i kept digging and can find plenty of 120-135 degree bits for wood but not so many for composites. I have found a couple but they are triple the price of the first one. The way I see it i have a few choices. I wait 6-8 weeks, I pay triple the price, I try to figure out how to use a 90 degree bit with several passes to make up the difference or I come to you guys and ask you where i can get a bit, or how I can do it with a 60 degree or 90 degree. I want whats cheap and fast. (of course) lets hear the suggestions!

we use a ballnose bit that is bigger than the diebond it lets us bend more then the 90%

whats the diameter of the bit you use? and what thickness dibond are you talking? Im using 3MM

Call Fred at centuriontools.com they have nice sharp 120 bit and could probably make you what you need for a reasonable price if it is a special order.

a sharp cut tends to cause the dibond to break. so the ballnose is a good idea or a straight bit.
