1.1mm Round Shank Drill Hard 60mm
Expensive but last a long time. All Quick Fit Drills, and those round shank Drills with a diameter of 3.2mm or more, come in short and long lengths. These Drills are much stiffer than implant quality ones. Particularly recommended for Drills less than 3.2mm diameter. - 0.45 inches diameter/ 1.1mm diameter/ 60 mm length.
