Effective Tree Stump Removal: Use these copper nails to accelerate the removal of tree stumps. The release of copper ions inhibits the growth and recovery of tree tissues, promoting efficient and thorough stump elimination. Reusable and Economical: Designed for multiple uses, these copper nails can be removed and reused, offering a cost-effective solution for controlling unwanted tree growth. For best results on trees over two feet in diameter, use ten or more nails. User-Friendly Installation: Made from soft copper, these nails can be easily hammered into pre-drilled holes in the stump using the included cobalt drill bit. This ensures even distribution and deep penetration for maximum effectiveness. Quality Materials: Constructed from 99% pure copper, these nails are thicker and more durable than standard options. The set includes cobalt drill bits known for high-temperature resistance and long-lasting performance, providing excellent rust resistance.
