This battery powered electric rebar tying tool is lightweight and has a compact easy to hold body. It runs on a 14.4V Lithium-Ion quick-charge battery that drives a brushless twisting motor. Like our standard BNT-40, the BNT-25 automatic rebar tying tool is designed to conserve wire by tying up to one #4 rebar and a #3 rebar together with three wraps of 21 gauge zinc coated wire. It comes with two batteries, a charger and four spools of wire ready to use. Its also a handy tool for tying wire mesh. USA-Made Wire and Poly-Coated Wire spools are also available for all of this tool!
