3-Thread Borer

Three-Thread Borers are made from the finest Swedish steel charcoal. Teflon® coated for easy starting into the tree. Plastic-covered handle prevents rust. Rubber end caps. Includes handle, bit and extractor. Two-Thread Borers feature the same construction but with two threads, so they turn slower in the tree and generate more strength when drilling. Replacement Bits, Extractors and Borer Handles also available.
