Specifications: Material: High-quality carbon steel Size: 32 mm (1.26 inch), 42 mm (1.65 inch), 45 mm (1.77 inch) Shape of the bits: Round, square, hexagon Efficient firewood splitting: This firewood splitter drill bit is designed to help split wood quickly, especially small or already thin pieces such as kindling. Best performance is achieved on smaller sections. Please note that extremely hard woods, wet woods, or very large logs may be difficult to split. Suitable for soft woods: The log splitter works effectively on soft and dry wood, such as pine. It is not recommended for hardwoods like oak, knotty wood, or wet wood. For logs approximately 20 cm in width, multiple splitting passes are advised. Hold the wood securely to prevent it from rotating with the bit. Easy to use: Proper usage is key. Drill straight and begin at the edge of the log—do not start in the center or at an angle. For logs over 20 cm in diameter, pre-split the log using another tool before using this drill bit to improve efficiency and reduce effort. Compatibility: Works with various power drills including hammer drills, impact drills, corded and cordless drills. Optimal results are achieved when used with appropriate electric drills on soft and dry wood. Strong and durable: Made from high-carbon steel with precision machining and fine threading. Offers high impact resistance and wear resistance. Designed with a penetrating head to effectively separate wood fibers. A powerful drill enables fast splitting, even in denser softwoods. Power recommendations: The 45 mm log splitter is intended for heavy-duty applications and best used with a hammer drill. The 32 mm log splitter is suitable for light-duty use. Recommended minimum power: 750W for electric drills, 500W for hand drills. Not compatible with impact-only electric drills that lack standard drilling function or those using three-jaw chuck systems. Package includes: 1 x Drill, 3 x Bits
