Our tire reamer bits are essential tools for tire repair, designed to efficiently smooth and enlarge puncture holes before inserting mushroom plugs. Made from high-quality carbide, these bits are engineered for durability and precision. With sharp serrated edges, they effectively clean the tire's broken area, removing impurities like rust, chippings, and steel wire layers, ensuring a clean, smooth surface for better mushroom plug sealing. Available in sizes ranging from 3mm to 13mm, our tire reamer bits cater to all types of vehicles, from small cars to heavy-duty machinery. For optimal performance, use these bits with a low-speed electric grinder or pneumatic tool, with a maximum speed of 500 RPM. Doma’s tire reamer bits are built to last longer and provide higher efficiency, offering superior performance over other brands.
