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. Performance improves with smaller wood 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 use on hardwoods like oak, knotty wood, or wet wood. For wood approximately 20 cm in width, multiple splitting passes may be required. Secure the wood during use to prevent it from rotating with the bit. Easy to use: Proper technique is important. Drill straight and begin at the edge of the log—do not start in the center or drill at an angle. For logs larger than 20 cm in diameter, pre-split the log using another tool before using this drill bit to improve efficiency and reduce strain on the tool. Compatibility: These 32 mm, 42 mm, and 45 mm wood splitter drill bits are compatible with various power drills, including hammer drills, impact drills, and corded or cordless drills. Optimal performance is achieved when used with appropriate electric drills on soft, dry wood. Durable construction: Made from high-carbon steel with fine threading, these drill bits are precisely machined for strength, 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, even with denser softwoods. 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. - Use an electric drill with at least 750W power or a hand drill with at least 500W power. Not compatible with standard electric drills that have only basic chuck functionality or three-jaw chucks without sufficient torque. Package includes: 1 x Festberg drill 3 x Splitter bits
