Description
The Irwin 21-Piece Black & Gold Oxide TurboMax Drill Bit Set (73149) is a comprehensive collection of jobber-length bits engineered for professional performance and efficiency. This set, model number 73149, is designed to meet the demands of a wide range of drilling tasks, particularly in metal. Each bit is crafted from M-2 high-speed steel, a material known for its excellent strength and heat resistance, which allows it to maintain a sharp edge even under high-stress conditions. The black and gold oxide finish provides an extra layer of protection, offering maximum corrosion resistance and contributing to a longer tool life.
