Makita XGC01Z 18V LXT Lithium-Ion Cordless 10 oz. Caulk & Adhesive Gun,

The Makita XGC01Z 18V LXT Cordless Caulk and Adhesive Gun provides motorized dispensing power for applying heavy sealants and construction adhesives. It eliminates the hand fatigue of manual squeeze guns, making it well suited for builders, remodelers, and tradespeople who regularly push high-viscosity materials through standard cartridges.

A built-in motor generates up to 1,100 pounds of dispensing force, which easily handles the thickest compounds. Application speed is managed through a 5-speed dial that regulates flow rates between 0 and 66 inches per minute, paired with a variable speed trigger for instant fine-tuning during continuous runs.

Maneuverability and clean application are central to the design. The cartridge holder rotates a full 360 degrees to maintain steady bead alignment around obstacles, while an automatic drip-reduction mechanism immediately releases internal pressure when the trigger is released to prevent unwanted material discharge.

As a bare tool running on an 18V LXT battery platform, it requires an existing compatible battery to operate. The holder is also specifically sized for 10 oz. and 300 ml tubes, meaning larger bulk sausages or oversize cartridges will not fit this configuration.

Verdict: The Makita XGC01Z is an excellent choice for anyone needing strong, consistent dispensing force for high-viscosity sealants. Its combination of speed regulation, rotating frame, and pressure relief makes it ideal for frequent caulking and gluing jobs.

• Dispensing Force: 1,100 lbs.
• Flow Rate: 0-66 IPM
• Speed Settings: 5-speed dial plus variable speed trigger
• Cartridge Compatibility: 10 oz. and 300 ml
• Holder Rotation: 360 degrees
• Power Source: 18V LXT Lithium-Ion battery system

A great fit if you:

• Apply high-viscosity construction adhesives or dense sealants frequently
• Want precise control over flow rates ranging up to 66 inches per minute
• Need to caulk around tight corners with a 360-degree rotating cartridge carriage
• Rely on standard 10 oz. or 300 ml material tubes

Consider something else if you:

• Use large sausage packs or cartridge sizes outside the 10 oz. and 300 ml range
• Do not own compatible 18V cordless platform batteries

What sizes of caulk tubes fit into this tool?
The 360-degree rotatable holder accommodates standard 10 oz. and 300 ml cartridges.

How does the tool prevent messy drips after stopping?
It features an automatic drip-reduction function that immediately relieves pressure on the tube whenever you let go of the trigger.

What flow rate range does this caulk gun offer?
The 5-speed control dial adjusts the material flow rate from 0 to 66 inches per minute (IPM).
