H48LQ torpedo, Q-Finisher for working on labial surfaces of composites. FG 314 shank, size 012 (1.2mm diameter), with 8mm working length. Q-Finisher for efficient work on composites to achieve optimal results. Tungsten carbide finishers create smooth surfaces in little time and Q-Finishers provide a more efficient finishing procedure. A better surface quality can be achieved after just one finishing step, due to the cross cut toothing specially designed for work on fillings.
