Caulking Guns

12 products

A caulking gun is one of those tools every contractor reaches for constantly, sealing window and door frames, running bead on trim, applying adhesives, and weatherproofing on new construction and remodel jobs. Getting the right one matters more than most people give it credit for.
Polar Tool & Supply carries a selection of professional-grade caulk guns built for the kind of volume and precision that contractors in Minnesota and Wisconsin actually deal with on the jobsite. That means smooth-rod frames with low-force ratchet drives for consistent bead control, heavy-duty barrel construction that holds up to repeated drops, and cordless electric caulking gun options from Milwaukee and DeWalt that work off the same M18 and 20V Max batteries your crew is already running.
Manual caulk guns are the standard for most applications and are lightweight, reliable, and available in 10 oz and 29 oz tube capacities to handle both standard cartridges and larger sausage packs for high-volume work.
Cordless caulking guns eliminate hand fatigue on long runs and give you consistent flow rate that's hard to match with a manual trigger. If your crew does a lot of siding, window installation, or exterior sealing, a battery-powered caulk gun pays for itself quickly.
Polar Tool has been supplying contractors across the Twin Cities, Superior, and Altoona areas for over 18 years. Order online at polartool.us or stop into any of our three locations.
