The Bosch Professional Auger Bit is ideal for fast drilling and accuracy when producing through-holes, pre-drilling for rafter nails, and drilling deep dowel holes in wood. Its heavy-duty self-feeding tip pulls the bit through completely, allowing for quick and effortless precision-drilling. The bit's optimized low-friction flute geometry with a solid center ensures straight holes, high chip removal, and increased speed. The optimized scoring spur and precision-ground main cutting edge produce accurate holes. This bit is perfect for ancillary building trades, carpenters, and roofers, suitable for both soft and hard wood. It features a hexagonal shank system compatible with all drill drivers with a 13-mm chuck.
