DEWALT DCS382B vs DCS387B Comparison

Motor Type

Edge: DEWALT 20V Brushless Reciprocating Saw

The DEWALT DCS382B features a brushless motor, which the product data highlights for optimized cutting power and efficiency. Brushless motors typically offer longer run times and increased durability compared to brushed alternatives. The DEWALT 20V MAX Compact Reciprocating Saw (DCS387B) does not explicitly list its motor type in the provided specifications. This leaves the internal drive mechanism of the DCS387B unclear. If the DCS387B uses a brushed motor, the DCS382B holds a clear technological advantage. You should consider this efficiency gain if you plan to run the tool for extended periods without battery swaps.

Blade Clamp

Edge: DEWALT 20V MAX Compact Reciprocating Saw

Blade changes are a frequent part of using a reciprocating saw. The DCS382B uses a twist-style keyless blade clamp for quick changes. The DCS387B offers a 4-position blade clamp that is also tool-free. This 4-position feature on the DCS387B allows for flush cutting and increased positional versatility, which the DCS382B data does not mention. If you need to cut flush against a wall or pipe, the DCS387B design provides specific mechanical advantages. The DCS382B clamp is simple but lacks the multi-position flexibility listed for the DCS387B.

Variable Speed

Edge: DEWALT 20V MAX Compact Reciprocating Saw

Both tools include a variable speed trigger for control. The DCS387B specifies a speed range of 0 to 2,900 strokes per minute. This wide range allows for precision cuts in delicate materials or fast cuts in hard wood. The DCS382B is described as having a 2-finger variable trigger design for ease of use, but it does not list a specific maximum strokes per minute value. Without that number, you cannot confirm if it matches or exceeds the DCS387B. However, the explicit SPM rating on the DCS387B gives you more confidence in its speed capabilities.

Included Tools

Edge: DEWALT 20V MAX Compact Reciprocating Saw

You must check what comes in the box. Both the DCS382B and the DCS387B are sold as bare tools, meaning neither includes a battery or charger. However, the DCS387B attributes list it as including a work light, which aligns with its feature list mentioning a bright LED. The DCS382B features list does not mention an LED light. If you often work in dark attics or crawl spaces, the DCS387B provides built-in illumination. The DCS382B lacks this specific included tool in its description, requiring you to rely on external lighting.

Stroke Length

Edge: Tie

The stroke length determines how much material the saw removes with each pass. Both the DEWALT DCS382B and the DEWALT 20V MAX Compact Reciprocating Saw share a 1-1/8 inch stroke length. This identical specification means both tools offer the same potential cutting speed and power per stroke. Neither tool has an advantage here. You can expect similar performance in terms of raw cutting aggression from either saw, as this core mechanical specification is exactly the same for both models.

Which 20V Recip Saw Fits Your Job

Users needing precision in tight spots

Our pick: DEWALT 20V MAX Compact Reciprocating Saw

The DCS387B measures 14 inches in total length, allowing it to fit between studs and work in confined spaces. Its 4-position blade clamp enables flush cutting and offers increased positional versatility. The variable-speed trigger ranges from 0 to 2,900 strokes per minute, giving you control for precision cuts where accuracy matters most.

Professionals prioritizing motor efficiency

Our pick: DEWALT 20V Brushless Reciprocating Saw

This model features a brushless motor, which DEWALT notes for optimized cutting power and efficiency. Brushless motors often provide longer run times and greater durability. The 2-finger variable trigger design offers ease of use, while the compact size ensures a high range of motion for demanding tasks where sustained power is critical.

Those valuing added visibility

Our pick: DEWALT 20V MAX Compact Reciprocating Saw

The DCS387B includes a bright LED light that illuminates dark work areas for better visibility. This feature helps you see your cut line clearly in low-light conditions. Combined with the pivoting shoe for versatility and the tool-free blade changes, it adds practical utility for jobsites where lighting is often limited or uneven.
