The most powerful cordless caulk and adhesive gun on the market offers the most bead control. Deliver caulk or adhesives smoothly and steadily, even with the highest viscosity materials, with the incredible pushing force of the M18TM Cordless 10-oz Caulk and Adhesive Gun. All-metal gears provide an industry-leading 950 lbs of force, and CFTTM Constant Flow Technology eliminates motor oscillation for steady dispensing and even beads at all viscosity levels. A variable-speed trigger and six-setting maximum speed dial optimize the tool’s 0-21 inches per minute (IPM) flow rate.  The exclusive Milwaukee® anti-drip mechanism prevents oozing of excess material when the trigger is released. A rotating collar gives you maximum bead control around turns, and the quick-change carriage design lets you change between 10-oz, quart and sausage-style containers. The M18 REDLITHIUMTM Battery (sold separately) lets you dispense more than 200 10-oz tubes of construction adhesive on one charge. The gun comes with a 10-oz carriage, 10-oz plunger rod and piston assembly.
