Floating device included for safety. If the drill rod detaches from the drilling machine, the auger can float on the water surface, making recovery easier and reducing loss. Sturdy construction. Made of aluminum alloy and nylon for good tensile strength and impact resistance, while remaining lightweight for easy handling. Carbide blade. Carbide blade is sharp and durable, designed to cut through ice with ease. Comes with a protective device to help prevent blade damage during storage or transport. 28 inch length and 6 inch diameter. The length and diameter are chosen for deep water bodies and thick ice layers, providing reliable performance in demanding conditions. Use scenarios - Ice fishing on large lakes with thick ice where reliable cutting power and reach are needed. - Drilling holes from a boat, dock, or other elevated position to access deep water. - Expeditions in harsh cold environments where maintaining blade integrity and easy recovery if a rod is dropped matters.
