✅ Highlights

1. Cordless Power with Real Performance

Contractors and home-improvement reviewers alike confirm that this cordless model stacks up well against corded versions, providing impressive power and endurance—even under heavy workloads .

2. All-Metal Bevel and Blade System

The metal bevel shoe includes positive stops at common angles, enabling clean, precise bevel cuts. The durable, lever-activated, keyless blade clamp accepts standard T-shank blades for robust performance.

3. Orbital Action and Variable Speed

Four orbital settings allow customization for smoother curves or faster rough cuts. The variable-speed trigger helps tailor the SPM to material and blade type.

4. Dust Blower Enhances Visibility

The built-in blower keeps your cut line free from debris—great for precision work and maintaining accuracy on curves .

⚠️ Potential Limitations

📉 Non-Brushless Motor

As highlighted in community forums, the DCS331B uses a brushed motor—less efficient and with shorter runtime compared to brushless successors like the DCS334B. That said, if your usage is occasional, brushing likely suffices and costs less upfront.

⚠️ No Battery or Charger Included

This is a tool-only purchase. If you’re new to the 20V platform, you’ll need to add the battery and charger separately — a consideration for true newcomers.

💬 What Users Say

From forums and professional reviews:

“It works great for me. If I needed to use one more often then the brushless would be the way to go.”

Pro reviews confirm contractor-grade performance:

“Powerful cordless jigsaw… fills that gap” for tasks like cabinet or stair cuts, matching many corded models on power and cut quality

🛠️ Pro Tips for Use

1. Upgrade to a brushless model if you're cutting daily—better efficiency and power.
2. Keep high-quality T-shank blades ready; perfect alignment with the bevel shoe ensures cleaner cuts.
3. Adjust orbital settings: use lower settings for fine curves, higher for fast roughing.
4. Use 20V batteries of 3Ah or more for enough runtime and consistent performance.
