21V Cordless Caulking Gun, 4-Speed, 300 ml Hard Adhesive
Key points
- 80 to 300 kg of thrust moves the stiff sealants that stall lighter guns
- Four feed speeds from 77 to 196 mm per minute match the bead to the joint
- Locking trigger keeps the bead flowing without constant hand pressure
- Battery gauge shows remaining charge before a long run is finished
- Site crews can leave manual skeleton guns in the van for structural sealing work, because the tool supplies the force the operator would otherwise lean into all day
- Accepts standard 300 ml cartridges (52 x 220 mm), the format most structural and tile adhesives are supplied in

Product detail
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. On a run at height, a fitter can pause part-way, move the ladder and pick up the bead again, because the plunger holds position when the trigger is released. Specified for construction adhesives and hard cartridges that a hand gun cannot push; the multi-speed feed lets the operator match flow to bead width, which is what keeps a panel adhesive job neat on a vertical surface.
