This new set from God Hand includes the set of 5 spin mold blades, which are perfect for carving flat-bottom holes in your model kits without the need for a pilot hole! Also included in this set is the short power pin vise, which allows greater precision in drilling due to its shorter size. Using the two in conjunction, you can start and finish drilling flat-bottom holes of 5 different diameters--1, 1.5, 2, 2.5, and 3mm!
