I have cut a lot of acrylic with a 1/8 inch bit and always have to spend time cleaning up the edges. It heats the plastic, folds it over and makes a mess. I end up using a deburring tool and sand paper to get a clean edge. With the O"Flute bit, all of that is a thing of the past. The edges were perfectly clean! No sanding, no deburring. This bit will pay for itself, just in the time saved. If you cut out acrylic on your CNC, this is a must have!
