The Pin Vice is ideal for drilling precise holes where an electric drill is just too cumbersome. The Pin Vice can be used for drilling holes into Delrin Eyes (with a drill bit) so you can insert a pin and move for animation. It's also a handy holder for not just for drills but taps, pins etc (0-1.2mm, 1.3-2.4mm & 0.8-2.0mm, 1.8-2.9mm) Please note, this Pin Vice does not come with drill bits.
