The straight fissure (cylinder) head has parallel sides and a flat end, so it cuts straight-walled slots, flat steps and parallel surfaces. At 1.4 mm the head is a general-purpose size for routine lab shaping and contouring. As a medium crosscut cutter it does the main shaping work between bulk reduction and finishing.
