10 Best Cordless Caulk Guns 2025 in the United States

The DEWALT 20V MAX Cordless Caulking Gun is designed for both DIY enthusiasts and professionals who need a reliable tool for applying adhesive. One of its standout features is the variable speed trigger, which allows users to control the flow of caulk with precision. This is particularly useful when working on detailed projects where accuracy is crucial. Additionally, the speed dial lets you set both maximum and minimum flow rates, offering flexibility for different applications.

The anti-drip feature is another significant advantage, as it automatically retracts the plunging rod when the trigger is released, preventing messy drips and waste. This makes it easier to work neatly, especially in tight spots. The quick-connect interchangeable canister trays add convenience, allowing users to switch between different cartridge sizes without hassle, which can save valuable time.

The built-in LED light is a great addition for working in dimly lit areas, ensuring visibility as you apply your adhesive. The hang hook for easy storage is also practical, making it a user-friendly option for both home projects and professional work.

The Milwaukee 2641-20 M18 10 oz Caulk Gun excels in ease of use and durability, making it a solid choice for both DIY enthusiasts and professionals looking for a reliable tool for their projects. Weighing in at 4.9 pounds, it strikes a balance between portability and sturdiness, which is beneficial for extended use without causing excessive fatigue. The cordless design adds to its convenience, allowing for unrestricted movement while applying caulk.

One of the standout features is its user-friendly design that simplifies handling, which can be especially helpful for those who may not have extensive experience with caulk guns. However, it’s worth noting that the product is sold as a tool only, meaning you'll need to invest in compatible batteries and chargers separately. This could be a drawback for users who are just starting and don’t already own Milwaukee M18 batteries.

The cartridge size compatibility is limited to 10 oz, which might be a constraint for those who use larger cartridges frequently. Also, while it boasts high durability, the actual longevity and performance under heavy use would require real-world testing to fully assess. The Milwaukee 2641-20 is likely a great fit for users who need a lightweight, durable caulk gun for occasional to moderate use, though those requiring larger capacities or already possessing other brands' batteries may want to weigh their options carefully.

The Milwaukee 2642-21CT M18 Sausage Caulk Gun Kit is a sturdy and well-built cordless caulk gun that users will find easy to handle thanks to its ergonomic design. It comes with an 18-volt lithium-ion battery included, so you can start using it right away without needing to buy separate batteries. The 6.5-pound weight makes it a bit heavier than some other models, which might cause some fatigue during prolonged use. The tool is compatible with sausage-style cartridges, which are common in professional sealing jobs.

It does not mention adjustable speed control, so users might find it a bit limited if they need fine control over the bead size or flow. Durability is a strong point here, with metal and plastic construction backed by a 5-year warranty, making it a reliable choice for regular use. This caulk gun is well suited for those who want a durable, ready-to-use cordless option for medium to heavy sealing tasks but may not suit users who need a lightweight or highly adjustable speed control feature.
