Key Features to Consider When Comparing Power
Beyond just the model name, there are specific features that will tell you how a DeWalt reciprocating saw performs. Comparing these will help you make the best choice:
Brushless vs. Brushed Motors
This is a crucial distinction for power and longevity. Most modern, higher-end DeWalt reciprocating saws feature brushless motors. Here’s why that matters:
- Brushless:
- More efficient power delivery
- Less heat generated, leading to longer motor life
- Better control and more consistent speed under load
- Typically more powerful for their size
- Brushed:
- Traditional motor design
- Brushes wear out over time, requiring replacement
- Can be less efficient and generate more heat
- Often found in older or more budget-friendly models
For comparing the best power, you’ll almost always want to lean towards DeWalt’s brushless offerings.
Stroke Length: The Closer the Better for Tougher Materials
Think of stroke length like the stride of a runner. A longer stride can cover more ground with each step. In a reciprocating saw, a longer stroke length means the blade can cut through thicker materials more aggressively.
- Short Stroke (e.g., 3/4 inch to 1 inch):
- Great for detail work and cutting thinner materials.
- Offers more control.
- Less efficient for thick lumber or demolition.
- Long Stroke (e.g., 1 1/8 inch to 1 1/4 inch):
- Ideal for aggressive cutting through thick wood, metal, and demolition.
- Faster cutting speed.
- Can be slightly less precise for fine work.
If your primary concern is raw cutting power through challenging materials, a longer stroke length is a significant advantage.
Strokes Per Minute (SPM) & Variable Speed Trigger
SPM is like the cardiovascular rate of the saw. More strokes per minute mean faster cutting. However, it’s not just about the maximum speed; it’s about control, too.
- High SPM (e.g., 3,000+): Essential for quickly cutting through wood and softer materials.
- Variable Speed Trigger: This is a lifesaver! It allows you to adjust the SPM on the fly. You can start a cut slowly and precisely, then ramp up the speed for faster material removal once the blade is engaged. This is crucial for safety and for cutting different materials. For instance, cutting metal often requires lower speeds to prevent overheating the blade and material.
When comparing, look for saws with a high maximum SPM and always ensure they have a variable speed trigger for optimal control and versatility.
