Specifications: Material: High-quality carbon steel Size: 32 mm (1.26 inches), 42 mm (1.65 inches), 45 mm (1.77 inches) Shape of the bits: Round, square, hexagon Efficient firewood splitting: The firewood splitter drill bit is designed to help split wood quickly, especially smaller pieces, thin logs, and kindling. Performance improves with smaller wood sections. Extremely hard, wet, 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 may be required. Secure the wood during use 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 larger than 20 cm in diameter, pre-split the log using another tool before using this drill bit to improve efficiency and reduce effort. Compatible with various power drills: These 32 mm, 42 mm, and 45 mm wood splitter bits work with hammer drills, impact drills, corded, and cordless drills. Best results are achieved when used with appropriate electric drills on soft and dry wood. Durable construction: Made from high-carbon steel with fine threading, these drill bits are strong, impact-resistant, and wear-resistant. The design allows deep penetration to effectively separate wood fibers. A powerful drill enables fast splitting, even with denser wood types. Power recommendations: The 45 mm log splitter is intended for heavy-duty use and best paired with a hammer drill. The 32 mm log splitter is suitable for light-duty use. We recommend using an electric drill with at least 750W power or a hand drill with at least 500W power. Not compatible with electric drills that have only pure rotary function or three-jaw chuck systems. Package includes: 1 x Drill, 3 x Splitter bits
