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: This firewood splitter drill bit is designed to help split wood quickly, especially small or already thin pieces such as kindling. Best performance is achieved on smaller logs. Please note that extremely hard woods, wet woods, or large logs may be difficult to split. Suitable for soft woods: The log splitter works effectively on soft and dry wood types 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 firmly during use to prevent rotation. Easy to use: Proper usage is key. Drill straight and begin at the edge of the log—avoid drilling into the center first or applying angled pressure. For logs larger than 20 cm in diameter, pre-split the log using another tool before using this bit to improve efficiency and reduce strain on equipment. 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. Optimal results are achieved when used with appropriate electric drills on soft, dry wood. Durable construction: Made from high-carbon steel with precision machining and fine threading, these drill bits offer high strength, excellent impact resistance, and wear resistance. The design allows the head to penetrate and separate wood efficiently. A powerful drill can significantly speed up splitting, even with denser softwoods. Power recommendations: The 45 mm log splitter is intended for heavy-duty applications and performs best with a hammer drill. The 32 mm bit 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 drivers that have only electric drive mode or three-jaw chuck systems. Package includes: 1 x Drill 3 x Bits
