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 sections. 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 wood approximately 20 cm in width, multiple splitting operations may be required. Secure the wood firmly to prevent it from rotating during use. Easy to use: Proper technique is essential. Drill straight and begin at the edge of the log—avoid drilling into the center first or angling the bit. For logs over 20 cm in diameter, pre-split the log using another tool before using this drill bit to improve efficiency and reduce effort. Compatibility: Works with various power drills including hammer drills, impact drills, corded and cordless drills. Best results are achieved when used with appropriate electric drills on soft, dry wood. Durable construction: 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 enables fast splitting, even with denser wood types. Power recommendations: The 45 mm log splitter is intended for heavy-duty applications and performs best with a hammer drill. The 32 mm log splitter is suitable for lighter tasks. We recommend using an electric drill with at least 750 W power or a hand drill with at least 500 W power. Not compatible with impact electric drills that have only pure electric drill function and three-jaw chuck systems. Package includes: 1 x Festberg drill 3 x Bits
