Irwin masonry drill bits are the most efficient and durable masonry drill bits on the market. Thanks to their carbide tips, their service life and efficiency are guaranteed in all masonry materials. The structure of the tip of the bit is shaped so that it cuts the material strongly, guaranteeing a 15% higher drilling speed compared to normal bits. Thanks to the unique brazing process, the connection of the bit between the shank and the arc is very strong. Thanks to the single-flute structure, the bit removes chips 60% more efficiently than similar products. Carbide tipHigh-cutting tipUnique brazing processSingle-flute structure
