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 pieces, thin logs, and kindling. Best results are achieved with smaller pieces. Please note that extremely hard woods, wet woods, or large logs may be 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 logs approximately 20 cm in width, multiple splits may be required. Secure the wood 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 drill bit to save time and effort. Compatible with various power drills including hammer drills, impact drills, corded and cordless drills. Best performance is achieved when used with appropriate electric drills on soft, dry wood. Strong and durable: Made from high-carbon steel with fine threading, these drill bits are strong, impact-resistant, and wear-resistant. The design allows the head to penetrate and separate wood effectively. A powerful drill can make splitting fast and efficient, even with harder woods. Power recommendations: The 45 mm log splitter is intended for heavy-duty use and should be used with a hammer drill. The 32 mm log splitter is 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 suitable for impact electric drills with only standard electric drill function or three-jaw chuck drills. Package includes: 1 x Festberg drill 3 x Bits
