The cylinder round head presents a long parallel cutting edge with a rounded end, for fast, even reduction of flat and convex acrylic and framework surfaces. At 2.3 mm the head is a general-purpose size for routine lab shaping and contouring. With its fine crosscut it is a finishing cutter, smoothing what a medium or coarse cutter has shaped.
