Dormer’s A720 is a metric micro drill, supplied in very small diameters ranging from 0. 15 mm to 1. 40 mm. To make tool holding easier, all drills have either a 1. 00 mm or 1. 50 mm shank diameter. The drills all have a 118 degree 4 - facet point which is a good aid to self-centring and reduces the amount of force needed to drill a hole. The drills have a bright finish to prevent work piece material from sticking to the cutting edge and are made from High Speed cobalt so are also suitable for drilling abrasive materials.
