Specifications: Material: high-quality carbon steel Size: 32 mm, 42 mm, 45 mm Shape of the bits: round, square, hexagon Efficient firewood splitting: This firewood splitter drill bit is designed to help split wood quickly, especially small pieces, thin logs, and kindling. Best performance is achieved with smaller wood pieces. Note that very hard woods, wet woods, and large logs are more difficult to split Suitable for soft woods: The log splitter works best on soft and dry wood, such as pine. It is not recommended for hardwoods like oak, knotty wood, or wet wood. For wood approximately 20 cm wide, multiple splits may be needed. Hold the wood securely to prevent it from rotating during use Easy to use: Proper usage is key. Drill straight and always start at the edge—do not begin in the center or at an angle. For logs over 20 cm in diameter, pre-split the log using another tool before using this bit to save time and effort Compatible with various power drills: These 32 mm, 42 mm, and 45 mm wood splitter bits work with hammer drills, impact drills, corded and cordless drills. Best results are achieved when used with appropriate electric drills on soft and dry wood Durable construction: Made from high-carbon steel with fine threading, these drill bits are strong, impact-resistant, and wear-resistant. The design allows the bit to penetrate and separate wood efficiently. A powerful drill enhances splitting speed, even on harder wood types Power recommendations: The 45 mm log splitter is intended for heavy-duty use and works best with a hammer drill. The 32 mm log splitter is suitable for light-duty tasks. We recommend using an electric drill with at least 750 W power, or a hand drill with at least 500 W. Not compatible with impact electric drills that have only electric drill function or three-jaw clamping drill chucks Package includes: 1 x drill + 3 x bits
