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: Firewood splitter drill bit is an efficient tool to help you split wood quickly, especially small pieces of wood, already thin wood, and kindling. The smaller the piece, the better it works. Note that very hard woods, overly wet woods, and large logs are difficult to split Suitable for soft woods: The log splitter has a better splitting effect on soft and dry wood, such as pine. We do not recommend using it on hardwoods such as oak logs, knotty woods, or wet woods. If the wood is around 20 cm wide, split it in multiple steps. Hold the wood securely to prevent it from turning with the bit Easy to use: Use correctly by drilling straight and starting at the edge. Do not start drilling in the center or at an angle. For logs larger than 20 cm in diameter, pre-split the log in half with another tool before using this drill bit to save time and effort Compatible with various power drills: 32 mm, 42 mm, and 45 mm wood splitter bits work with hammer drills, impact drills, corded, and cordless drills. Best results are achieved with appropriate electric drills on soft and dry wood Strong and durable: Made from high-carbon steel with fine threading, these log splitter drill bits are strong, impact-resistant, and wear-resistant. The design allows the head to penetrate and separate wood effectively. A powerful drill enables fast splitting, even with harder woods Power recommendations: The 45 mm log splitter is designed for heavy-duty use and should be used with a hammer drill. The 32 mm log splitter is for light-duty use. We recommend an electric drill with at least 750 W power or a hand drill with at least 500 W power. Not suitable for impact electric drills with pure electric drill function or three-jaw chuck drill bits Package includes: 1 x Festberg drill + 3 x bits
