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: The firewood splitter drill bit is an efficient tool designed to help split wood quickly, especially small pieces, thin logs, and kindling. Performance improves with smaller wood pieces. Note that extremely hard woods, wet woods, or large logs may be difficult to split. Suitable for soft woods: This 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 are advised. Secure the wood firmly to prevent it from rotating with the bit. Easy to use: Proper usage is key. 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 in half 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 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, these log splitter drill bits are highly impact resistant and wear resistant. 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 designed for heavy-duty applications and is best used with a hammer drill. The 32 mm log splitter is intended for lighter tasks. 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 clamping drill chucks. Package includes: 1 x Festberg drill + 3 x bits
