I just received a 1/4" 30 degree scoring cutter from that same seller a couple days ago. It works great on Sintra, but 30 degrees is too steep of angle. I'm going to order some of his 45 degree bits and try them. The 30 was exactly what I was looking for, for cutting small letters in plastic, but it cut a little too deep and I did not want to have it clearance the bottom of the letters. I loved the quality of the 30 degree bit thou, it was head and shoulders above the china stuff. I'm just glad I found a use for the china bits I purchased. Honestly I think they would be good bits if they were sharpened. I have a diamond hone somewhere but have not been able to find it over last few days. The V-cutters come to a nice point and the point is right where it should be, they just don't seem to be sharp enough on the edges for good clean v-carving.
