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 passes may be required. Hold the wood securely to prevent it from rotating with the bit. Easy to use: Proper usage is key. Drill straight and always start at the edge—do not begin drilling 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. 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 and dry wood. Strong and durable: Made from high-carbon steel with precision machining and fine threading. These 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 in harder wood types.
