Equipped with a 21V high-torque motor engineered for heavy-duty industrial use, delivering apowerful thrust, capable of extruding high-viscosity materials with consistent pressure. The motor boasts power conversion efficiency, optimized for prolonged heavy-load operation while minimizing heat buildup, supporting 2 hours of continuous use without performance drops. Its sealed bearing design resists dust and debris, ensuring reliable performance in construction sites, workshops, or renovation projects.

Variable Speed Adjustment

Features an intuitive variable-speed trigger with a 0-6mm/s extrusion range, allowing users to fine-tune speed based on material viscosity and project requirements. For delicate tasks like window frame sealing or tile grouting, a gentle trigger pull delivers slow, controlled flow to avoid excess caulk and ensure neat, even application. For heavy-duty industrial work, such as large-area structural bonding or high-volume sealing—the full-trigger position unlocks maximum speed, cutting project time compared to manual guns.

Anti-DripTechnology

This cordless caulking gun comes with a smart anti-drip system that works instantly, once you let go of the trigger, the material flow stops right away. No more messy drips of caulk or adhesive getting on your work surfaces, which means way less cleanup after you’re done. Plus, there’s a built-in anti-siphon valve that prevents the caulk from flowing back into the gun. This keeps the pressure steady the whole time you’re using it, so the caulk comes out evenly from the first squeeze to the last. With this design, your work areas stay neat, you don’t have to spend extra time wiping up spills, and you won’t waste expensive materials by letting them drip or leak.

Ergonomic Industrial Design

Engineered to prioritize user comfort during long industrial shifts, the caulking gun features a reinforced yet lightweight structure. The ergonomic handle is wrapped in soft, anti-slip rubber with a contoured shape that fits naturally into palms of all sizes, distributing grip pressure evenly to reduce hand fatigue and soreness even after hours of continuous operation. Its optimized weight distribution shifts the center of gravity closer to the handle, alleviating wrist strain when working at overhead angles or in confined spaces.

Versatile Industrial Application

Designed to excel across a wide spectrum of industrial, construction, and DIY scenarios, this 21V cordless caulking gun offers unmatched versatility that eliminates the need for multiple specialized tools. It features universal compatibility with standard cartridges, including aluminum, plastic, and fiber options, catering to both small-scale touch-ups and large-volume industrial projects. The gun seamlessly handles all common sealing and bonding materials, from low-viscosity acrylic caulk for interior trim and window sealing to high-viscosity silicone for waterproofing bathrooms, kitchens, and exterior joints.

Industrial Safety and Durability

The gun’s body is made of reinforced aluminum alloy, which can stand up to bumps, rust, and damage from caulk or adhesive chemicals—perfect for the rough conditions of construction sites and industrial workshops. A trigger guard keeps the tool from turning on by accident, while the motor housing is designed to release heat, protecting internal parts from overheating even during long hours of use. The non-slip base has rubber feet that prevent sliding on wet or oily surfaces, and the battery compartment is sealed to keep out moisture and dust.
