This Bosch Auger Bit is designed for fast and accurate drilling in wood. It features a working length of 170mm and a total length of 235mm, with a diameter of 20mm (7/16 inch). The hexagonal shank system is compatible with all drill drivers with a 13-mm chuck. It is ideal for creating through-holes, pre-drilling for rafter nails, and drilling deep dowel holes in wood. The heavy-duty self-feeding tip ensures quick and effortless precision-drilling. Optimized low-friction flute geometry and a solid center contribute to straight holes, high chip removal, and increased speed. The optimized scoring spur and precision-ground main cutting edge ensure accurate holes. This bit is suitable for soft and hard wood and is particularly useful for ancillary building trades, carpenters, and roofers.
