Cordless caulking gun

Bosch Professional GCG 18V-600 Cordless Caulking Gun (body only)

Even beads without dripping — 9 feed settings and automatic material retraction.

The Bosch Professional GCG 18V-600 is an 18 V cordless caulking gun for sealing joints, windows and construction connections. It handles both 310 and 400 ml cartridges and 400 and 600 ml foil sachets, and is supplied without battery or charger.

9 feed settings for full control of the bead

A 9-step speed dial plus a variable-speed trigger let you match the flow to the joint width. The GCG 18V-600 lays an even bead on both fine window seals and wide structural joints.

3.5 kN push force for high-viscosity adhesives

With 3.5 kN of push force and up to 7 mm/sec feed rate, the caulking gun moves even high-viscosity adhesives quickly. Long joints get done without straining your hand across a full working day.

Automatic retraction stops dripping

Release the trigger and the GCG 18V-600 automatically retracts the plunger to cut the flow. Sealant stops oozing onto finished surfaces, so cleaning up takes minimal effort.

Works with every Bosch Professional 18 V battery

The caulking gun runs on any battery from the Bosch Professional 18 V system (AMPShare), so your existing packs are ready to go. It ships as a body-only tool, without battery or charger.
