EFFECTIVE TREE STUMP REMOVAL Use these copper nails to remove tree stumps and roots quickly and easily. By releasing high concentrations of copper ions, these nails inhibit the growth and regeneration of tree tissue, ensuring thorough and efficient removal. USER FRIENDLY INSTALLATION Thanks to their soft copper alloy, these nails are easy to hammer into pre-drilled holes in the tree stump with the included cobalt drill. This method ensures even distribution and effective penetration, thus maximising the efficiency of tree stump removal. Reusable and Economical: these copper nails are designed for multiple use and can be reused. This makes them a cost-effective solution for curbing unwanted tree growth. For best results on trees larger than 60cm in diameter, use of ten or more nails is recommended. Durable and resistant materials: these nails are made of 99% pure copper and are thicker and more durable than traditional nails. Together with the cobalt drill bits, which are for their high temperature resistance and durability, this set promises longevity as well as protection against rust and corrosion., Weight: 0.2645547144 Pounds, Manufacturer: Pinafresa
