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 pieces. Please 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 in width, multiple splitting passes may be required. Hold the wood securely to prevent it from rotating with the bit. Easy to use: Proper usage is key. Drill straight and always start at the edgedo 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 drill bit to save time and effort. Compatible with various power drills including hammer drills, impact drills, and corded or cordless drills. Best results are achieved when used with appropriate electric drills on soft, dry wood. Strong and durable: Made from high-carbon steel with fine threading, these log splitter drill bits are precisely machined for exceptional strength, high impact resistance, and wear resistance. The design allows the head to penetrate and separate wood effectively. A powerful drill can make firewood splitting fast and efficient. 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 use. We recommend using an electric drill with at least 750W power or a hand drill with at least 500W power. Not compatible with impact electric drills that have only pure electric drill function or three-jaw chuck systems. Package includes: 1 x Festberg drill 3 x Bits
