One of my suppliers has been advertising this cutter and I do turn a lot of acrylics so decided to spring for one and see how well it worked. They were really pushing it for inlace acrylics which are notoriously brittle and like to chip out.
Gave it a whirl and was pleasantly surprised. Gave a nice clean cut and no tearout/chipping, left a really nice smooth surface for sanding and polishing. Found the sweet spot for its use was between 2200 and 2300 RPM. Turned 18 or 20 Seam ripper handles without having to rotate the cutter, no noticeable loss of sharpness. I'll keep count and see just how many items I can get out of one cutter to figure out if it's cost effective or not over time.
Now for the downside, it is almost 20.00 for one, with the negative rake I don't really see any way to freshen it up with a diamond card once it gets dull.
