2.3 mm Predrill for 2.4 mm Shank Positive Pin [H090203]
More 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. Drill fragments do not cause a problem.
