Summary of Tool


The BNT-40 rebar tying tool is lightweight and has a compact, easy to hold grip. The tool is well balanced and is designed to tie rebars as fast as you can pull the trigger. Included with the tool are two lithium-ion batteries. The tool comes with four spools of 21 gauge tie wire. The tool is designed to tie up to #6 (20 mm) rebar. The long life battery will give you over 2000 ties on a single charge. The extra battery that is included can be charging while the other one is in use. The charger is designed for quick charging in less than 40 minutes. Our standard wire is galvanized plated to inhibit rust and corrosion. The 14.4V Lithium-Ion power pack quick-charge battery drives the tool’s brushless twisting motors. Each tool comes with two batteries, a quick charger and four spools of wire in a tough molded plastic carrying case ready to use.  Note: We also now offer wire made here in the USA!
