How to choose
Compatibility with Existing DeWalt Models
When searching for parts for the DCS391, verify specific compatibility to ensure a proper fit. For example, the 381091-00 Trim Saw Fence is explicitly listed for the DCS391B, while the N621119 steel outer clamp washer also supports the DCS391 alongside various other models like the DCS390 and DCS393. Always cross-reference the exact part number provided in the product description with your specific circular saw model to avoid purchasing incompatible hardware or accessories. Checking these manufacturer-specified lists helps maintain the structural integrity and intended functionality of your tool when performing routine maintenance or replacing worn components.
Essential Accessory Selection
Selecting the right accessories depends on the specific maintenance needs of your circular saw. If your current blade retention hardware is damaged, the N621119 steel outer clamp washer serves as a necessary replacement part. Conversely, if you require improved accuracy during long rip cuts, an edge guide is essential. The 381091-00 fence is designed specifically for trim saws including the DCS391B. Ensure you are not confusing accessories intended for newer models, such as the DW3278 kit which is compatible with the DCS575 and DCS570, as these may not fit the DCS391 chassis due to design variations.
Tool Kits versus Individual Units
Shoppers looking for a comprehensive power tool setup may consider a bundled approach, such as the DCK240C2 20V Lithium Drill Driver and Impact Combo Kit, which includes a 20V MAX circular saw. This option is ideal for those who need multiple cordless tools and batteries simultaneously. If you already possess a collection of DeWalt 20V batteries and chargers, you might opt for a bare tool, though availability varies. Bundles provide a unified power ecosystem, allowing you to swap batteries between the drill, impact driver, and circular saw without needing different charging interfaces or power standards.
Understanding Replacement Part Specifications
Replacement parts like the N621119 washer and the 381091-00 fence are engineered to restore the factory performance of your circular saw. When reviewing these items, note the listed compatibility groups. The N621119 is compatible with a wide range of older and current models, including the DCS390, DCS392, and DC310. Using parts explicitly vetted for your model ensures that the blade clamp or fence properly secures or guides the tool as intended. Always prioritize parts that list your specific model number to ensure the dimensions and mounting points match your existing equipment exactly.
Evaluating Alternative Saw Options
While searching for the DCS391, some shoppers encounter alternative options like the 20V Max brushless cordless circular saw. This unit features a 6-inch aluminum alloy blade, 5900 RPM performance, and a 2-1/20 inch cutting depth at 90 degrees. It is marketed as a lightweight 4.2-pound alternative compatible with DeWalt 20V batteries. When considering such alternatives, compare the specific feature sets, such as bevel capacity and weight, against the specifications of the original DCS391. Ensure the alternative meets your specific cutting requirements and ergonomic preferences before making a purchase decision for your workshop.
Frequently asked questions
Does the 381091-00 fence work with my DCS391B?
Yes, the 381091-00 trim saw fence is specifically listed as compatible with the DeWalt DCS391B. This accessory is designed to assist in making consistent, straight rip cuts by acting as an edge guide. Always ensure your specific saw model is listed on the packaging or product page before installation to guarantee the fence mounting hardware aligns correctly with your saw's base plate.
Can I use the N621119 clamp washer on a DCS390?
Yes, the N621119 steel outer clamp washer is compatible with the DeWalt DCS390, as well as the DCS391, DCS372, DCS392, DC310, DCS373, DCS393, and DC390B. This part is a durable replacement intended to secure the blade to the saw arbor. It serves as a replacement for several older part numbers, making it a versatile option for maintaining various DeWalt circular saw models.
Is the DCK240C2 kit the best way to get a circular saw?
The DCK240C2 20V Lithium Drill/Impact Combo Kit is a practical choice if you need a drill, an impact driver, and a circular saw in one purchase. It provides a complete 20V power tool ecosystem with batteries included. If you only require a circular saw, you might look for a bare tool or a dedicated saw kit, but this bundle is efficient for those building a tool collection.
Will the DW3278 fence kit fit my DCS391?
No, the DW3278 circular saw fence kit is explicitly listed for the DCS575, DCS570, DCS577, DWE575, and DWS535 models. It is not advertised as compatible with the DCS391. For the DCS391B, you should look for the 381091-00 trim saw fence, which is the model specifically designated for that unit in the provided product information.
How does the alternative 20V brushless saw compare to the DCS391?
The 20V brushless circular saw mentioned provides 5900 RPM, a 6-inch blade, and a 2-1/20 inch cutting depth at 90 degrees, weighing 4.2 lbs. It is designed for compatibility with DeWalt 20V batteries. While it offers brushless motor technology, you should compare these specific cutting depth and bevel capabilities against your DCS391 requirements to see if it meets your specific project needs for wood or PVC cutting.
Bottom line
For owners of the DeWalt DCS391 seeking to maintain or enhance their tool, the most effective approach is to source parts specifically validated for that model. The 381091-00 Trim Saw Fence is the definitive choice for adding edge-guiding capabilities to the DCS391B, ensuring a secure fit that generic guides cannot guarantee. Similarly, the N621119 steel outer clamp washer is the correct component for maintaining blade security, offering verified compatibility across the DCS390 series. While alternative brushless saws exist, relying on manufacturer-matched replacement parts like these ensures the long-term reliability and safety of your original DCS391 unit without the risks associated with using incompatible or improperly fitted third-party accessories.
When deciding how to support your DCS391, prioritize model-specific part numbers over general compatibility claims. If you are looking to expand your tool arsenal, evaluate whether a combo kit like the DCK240C2 offers better value than buying individual components. Always verify the part number against your specific saw label before purchase. If your needs have evolved beyond the capabilities of the DCS391, consider whether a newer brushless model might offer better performance, but ensure any new unit is compatible with your existing 20V battery platform to maintain efficiency across your workshop equipment.
