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, and large logs are more 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 splits may be required. Secure the wood firmly during use to prevent it from rotating with the bit. Easy to use: Proper usage is key. Drill straight and always start at the edgedo 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 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 drill bits are highly impact resistant, wear resistant, and built to last. The bit head is designed to penetrate and separate wood effectively. A powerful drill enables fast splitting, even with denser softwoods. 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 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 chuck systems. Package includes: 1 x Festberg drill 3 x Splitter bits
