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 smaller pieces, thin logs, and kindling. Performance improves with smaller wood sections. Please note that extremely hard woods, wet woods, or large diameter 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 splitting passes may be required. Secure the wood during use to prevent it from rotating with the bit. Easy to use: Proper technique is essential. Drill straight and begin at the edge of the log—do not start 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 improve efficiency and reduce strain. Compatible 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. Strong and durable: Made from high-carbon steel with precision machining and fine threading. Designed to be highly impact resistant and wear resistant. The bit head is engineered to penetrate and separate wood effectively. Use with a powerful drill for faster splitting performance. Power recommendations: The 45 mm log splitter is intended for heavy-duty applications and should be used with a hammer drill. The 32 mm log splitter is suitable for light-duty use. 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 drivers that have only electric drill function or three-jaw chuck systems. Package includes: 1 x Festberg drill 3 x Bits
