The Milwaukee 2641-20 M18 Cordless 10-oz Caulk and Adhesive Gun has all-metal gears provide 950 lbs of force. Constant Flow Technology eliminates motor oscillation for steady dispensing and even beads at all viscosity levels and a variable-speed trigger with six-setting speed dial optimize the tool’s 0-21 inches per minute (IPM) flow rate. Milwaukee anti-drip mechanism stops excess material when the trigger is released. A rotating collar gives you improved bead control around turns, and the carriage design lets you quickly change between 10-oz, quart and sausage-style containers. The M18 REDLITHIUM Battery (sold seperately) lets you dispense more than 200 10 oz tubes of construction adhesive on 1 charge. The kit includes an 18-volt compact battery, 30-minute charger, 20-oz aluminum sausage-style barrel, 10 oz plunger rod and piston assembly.
