Brad Nails Usage
Brad nails, typically 18-gauge and ranging from 5/8" to 2" in length, are the exclusive fastener type compatible with the DeWalt DCN660 nailer. Their thin profile—just 0.0475 inches in diameter—minimizes wood splitting, making them ideal for delicate trim work, cabinetry, and furniture assembly. Unlike finish nails, brad nails leave nearly invisible holes, often eliminating the need for wood putty when paired with a quality nailer like the DCN660.
Selecting the correct brad nail length is critical for material integrity. For 1/2" molding, use 1" brads; for 3/4" baseboards, opt for 1.5" nails. Overdriving or underdriving risks weakening joints or leaving unsightly protrusions. The DCN660’s depth adjustment feature ensures precision, but always test on scrap material first. Pro tip: Angle the nailer slightly downward when fastening near wood ends to prevent blowouts.
While brad nails excel in thin materials, they lack the holding power of larger fasteners. Avoid using them in load-bearing applications or outdoor projects without stainless steel variants. For structural tasks, consider 16-gauge finish nails or screws instead. However, for interior decorative work, brad nails paired with the DCN660 deliver unmatched efficiency and aesthetics, driving up to 1,200 nails per battery charge.
To maximize brad nail performance, maintain your DCN660 regularly. Clear jams immediately to prevent misfires, and use only DeWalt-recommended 18-gauge brads to avoid damage. Store nails in a dry environment to prevent rust, which can clog the tool. With proper technique and care, brad nails transform the DCN660 into a precision instrument for professional-grade finishing work.

Nail Length Range
The DeWalt DCN660 cordless finish nailer is a versatile tool, but its performance hinges on using the right nail length for your project. This nailer accommodates a specific range of 15-gauge finish nails, but within that category, length matters.
Nails too short won't penetrate deeply enough for a secure hold, while nails too long can protrude through the material or split the wood.
Understanding the Range: The DCN660 typically accepts 15-gauge finish nails ranging from 1 inch to 2-1/2 inches in length. This range allows for a variety of applications, from delicate trim work to heavier baseboard installation.
Material Thickness: The key factor in nail length selection is the combined thickness of the materials you're fastening. For example, when attaching 1/4-inch molding to 3/4-inch plywood, a 1-1/4 inch nail would be appropriate.
Practical Tips:
- Start with the Shortest Possible Nail: Always err on the side of caution and begin with the shortest nail that will provide adequate holding power. This minimizes the risk of splitting the wood.
- Test on Scrap Material: Before committing to a nail length, test it on a scrap piece of the same wood species and thickness you'll be using in your project. This allows you to see the nail's penetration depth and ensure it doesn't protrude.
- Consider Grain Direction: When nailing into wood, be mindful of the grain direction. Nailing against the grain requires slightly longer nails for a secure hold.
Beyond Length: Other Nail Considerations: While length is crucial, don't overlook other nail characteristics. Head type (flat, sunken, etc.) and coating (galvanized, stainless steel) also play a role in the nail's performance and appearance.
Refer to the DeWalt DCN660 manual for specific recommendations on compatible nail types and brands.
By carefully selecting the appropriate nail length within the DCN660's range and considering other nail characteristics, you can ensure professional-looking results and strong, lasting joints in your woodworking projects.

Wire vs. Plastic Collation
The DEWALT DCN660 nailer is a versatile tool, but its performance hinges on the collation type of the nails you choose. Wire and plastic collations each bring distinct advantages and drawbacks, influencing everything from tool longevity to environmental impact. Understanding these differences ensures you select the right nails for your project and maintain your tool’s efficiency.
Wire collation, often seen in heavy-duty applications, offers superior durability. The wire strips hold nails firmly, reducing the risk of jams in high-volume framing or roofing tasks. However, this strength comes with a trade-off: wire strips are less flexible and can be harsher on the tool’s internal components over time. For instance, prolonged use of wire-collated nails may accelerate wear on the DCN660’s feed system, necessitating more frequent maintenance. If you’re tackling large-scale projects where reliability is paramount, wire collation is a solid choice, but factor in the potential for increased tool upkeep.
Plastic collation, on the other hand, is lighter and more flexible, making it gentler on the nailer’s mechanism. This reduces friction and minimizes wear, potentially extending the tool’s lifespan. Plastic strips are also biodegradable, offering an eco-friendly alternative to wire. However, they are more prone to breakage, especially in cold temperatures, which can lead to misfeeds or jams. For interior trim work or smaller projects where precision and tool preservation are key, plastic collation excels. Always store plastic-collated nails in a temperature-controlled environment to prevent brittleness.
When deciding between wire and plastic, consider the project’s scale and conditions. Wire collation is ideal for demanding outdoor tasks like sheathing or subflooring, where its robustness shines. Plastic collation suits indoor or detail-oriented work, where its reduced tool impact and environmental benefits are more valuable. Always check the DCN660’s compatibility with specific nail lengths and gauges, as both collation types are available in various sizes. For example, 2-inch to 3.5-inch nails are common, but ensure the shank style (smooth, ring, or screw) aligns with your project needs.
In practice, alternating between wire and plastic collation based on the task can maximize both tool performance and longevity. Keep a stock of both types, and inspect the nailer’s feed system periodically to clear debris or adjust tension as needed. By tailoring your choice to the job at hand, you’ll optimize the DCN660’s efficiency while minimizing downtime and repair costs.
