Specifications: Material: High-quality carbon steel Size: 32 mm (1.26 inches), 42 mm (1.65 inches), 45 mm (1.77 inches) 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 best on smaller pieces. Hardwoods, wet woods, and large logs are more difficult to split. Suitable for soft woods: Works best on 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 log to prevent rotation during use. Easy to use: For optimal results, drill straight and begin at the edge—not the center—and avoid angling. For logs over 20 cm in diameter, pre-split with another tool before using this bit. Compatibility: Fits various power drills including hammer drills, impact drills, and corded or cordless drills. Best results achieved with appropriate electric drills on soft, dry wood. Durability: Precision-machined from high-carbon steel with fine threading. Highly impact-resistant and wear-resistant. Designed to penetrate and separate wood fibers effectively. Power recommendations: - 45 mm bit: Recommended for heavy-duty use with a hammer drill. - 32 mm bit: Suitable for light-duty use; minimum recommended power is 750 W for electric drills and 500 W for hand drills. Not compatible with impact drills that function only as standard electric drills or with three-jaw chucks. Package includes: 1 x Drill + 3 x Bits
