Dremel 115 5/16 inch Oval-Shaped High Speed Cutter for Wood, Fiberglass, Ceramics, Jewelry, and Soft Metals, 2-Pack

I had a pile of parts made on a 3D printer that needed rework to remove staircase artifacts and dimension adjustments to make them fit together. Some of the carving is into square corners. After trying several tools, the one that worked best was a predecessor of the 115 cutter that I found in my father's Dremel tool set, more than 60 years old. After wearing out that cutter, I needed a replacent and found the 115, which is same style and slightly larger than the old one. Mounted in a brand new 4000 handpiece, its performance is outstanding, shaving and shaping ABS plastic like butter.
