This set includes 15 pieces of Forstner drill bits with diameters from 10 to 50 mm. The drill bits with diameters from 10 to 30 mm have a clamping shank with 8 mm diameter, the drill bits with diameters from 35 to 50 mm have a clamping shank with 10 mm diameter. The cutting edges are made of high quality carbon tool steel. Thanks to the centring point, the drill bits can also be used perfectly with a hand-held drill in addition to being used in a stand or column drill. The two circumferential cutting edges ensure a clean, dimensionally stable bore that does not break or tear out at the drill edges. The drill bits from the set are suitable for soft and medium-hard wood types. For clear and proper storage, the Forstner drill bits are delivered in an aluminium box with foam insert.
