21V Cordless Caulking Gun, 4-Speed, 300 ml Hard Adhesive
Four-speed cordless caulking gun built for hard adhesive in a 300 ml cartridge, the format used for structural sealant, tile grout and window and door installation. A 21V motor drives the plunger through a 2000 mAh pack and generates between 80 and 300 kg of thrust, which is enough to move the stiffer sealants that stall lighter tools. Four feed rates from about 77 to 196 mm per minute let the operator match the bead to the joint: slow for a narrow control joint where accuracy matters, fast for long runs along a floor or frame. A locking trigger holds the plunger so the bead keeps flowing without hand pressure, and a battery gauge shows how much charge is left before a run is finished. At 1.5 kg with a 13 degree grip angle it stays comfortable over a long shift, and the tool is supplied bare with battery kits optional.
