In conjunction with the marine industry, the transom drill was developed to eliminate the problems associated with drilling through fiberglass and wood. Due to the special parabolic flute design, chip packing problems are eliminated and make short work of drilling through thick transoms. Micro-grain carbide tips and premium steel bodies ensure maximum performance and durability. This bit is ideal to drill mounting holes for outdrive gimbal brackets, outboard engine brackets, and drain holes. Can be re-sharpened or re-tipped.
