Specifications: Material: High-quality carbon steel Size: 32 mm (1.26 inch), 42 mm (1.65 inch), 45 mm (1.77 inch) Bit shapes: Round, square, hexagon Efficient firewood splitting: This drill bit is designed to split wood quickly, especially small, thin pieces and kindling. Performance is optimal on smaller pieces. Hardwoods, wet woods, and large logs may be difficult to split. Suitable for soft woods: Best results are achieved with soft, dry wood such as pine. Not recommended for hardwoods (e.g., oak), knotty wood, or wet wood. For logs approximately 20 cm in width, multiple passes may be required. Secure the wood firmly to prevent rotation during use. Easy to use: For best results, drill straight and begin at the edge—not the center—of the log. Avoid angling the bit. For logs over 20 cm in diameter, pre-splitting with another tool is recommended before using this bit. Compatibility: Compatible with various power drills, including hammer drills, impact drills, and corded or cordless drills. Optimal performance is achieved with appropriate electric drills on soft, dry wood. Durability: Precision-machined from high-carbon steel with fine threading. Highly impact resistant, wear resistant, and designed not to break. The bit head is engineered to penetrate and separate wood fibers. A powerful drill enables fast splitting—even of denser wood types. Power recommendations: The 45 mm bit is intended for heavy-duty use and is best used with a hammer drill. The 32 mm bit is suitable for light-duty applications. Recommended minimum power: 750 W for electric drills, 500 W for hand drills. Not compatible with impact drills that lack hammer function or with three-jaw chucks designed only for standard drill bits. Package includes: 1 x Drill bit holder + 3 x Bits
