Auger bit with a robust threaded tip. Precise positioning due to the long threaded tip. Quick tool change through the CENTROTEC interface. High corrosion resistance and low friction due to a special coating. Optimally tuned thread design allows for ideal chip removal. Suitable for deep blind and through holes in soft and hardwood: The CENTROTEC auger bits work precisely on rafters and beams. The optimally tuned thread design ensures ideal chip removal. The robust threaded tip allows for precise positioning of the drill bit and pulls it into the wood, enabling fatigue-free work. Thanks to the CENTROTEC interface, the auger bits can be changed in a flash. Additionally, they can be sharpened up to fifteen times - for fast progress and accurate drilling results.
