You are comparing a 20V MAX jigsaw against an 18V X2 circular saw. This 20V MAX vs 18V table saw guide focuses on their core specifications. Both tools use brushless motors for efficiency. The main difference lies in their power source and intended cut type. The DEWALT model runs on a single 20V battery. The Makita model uses two 18V batteries for higher voltage. You need to understand these specs to pick the right tool.
Key differences
| Aspect | DEWALT 20V MAX Cordless Brushless Jig Saw | Makita 18V X2 Brushless 7-1/4-Inch Rear Handle Saw |
|---|---|---|
| Voltage | 20V MAX | 18V (uses 2 batteries for 36V X2) |
| Motor Type | Brushless | Brushless |
| No-Load Speed | 3,200 Blade Speed | 5,100 RPM |
| Weight | 4.2 pounds | 12.1 pounds |
Which one should you choose?
Choose DEWALT 20V MAX Cordless Brushless Jig Saw if
- You need a lightweight tool for detailed, curved cuts.
- You prefer using a single battery from your existing 20V MAX system.
- You want a compact tool that fits in tight spaces.
Choose Makita 18V X2 Brushless 7-1/4-Inch Rear Handle Saw if
- You require more power for cutting thick lumber.
- You already own two 18V LXT batteries.
- You need a larger blade for deeper cutting capacity.
Verdict: The DEWALT jigsaw is the better choice for precision work and portability. The Makita circular saw offers more raw power for ripping through thick materials. Choose the DEWALT for detail work and the Makita for structural cuts.
Voltage and Power Source Differences
Voltage System
Product A uses a standard 20V MAX battery system. Product B utilizes 18V X2 technology, which combines two 18V batteries to create a 36V power source. This dual-battery setup in Product B allows for higher output compared to the single 20V pack in Product A. You get more raw power from the Makita configuration, which helps with demanding cuts. The DEWALT tool relies on its brushless motor efficiency to maximize runtime from its single battery. Your choice depends on whether you prefer the simplicity of one battery or the extra torque from two.
Motor Type
Both tools feature brushless motors, which is a significant advantage for modern cordless power tools. Product A highlights its brushless motor for efficient performance and longer runtime compared to older brushed models. Product B also uses an electronically controlled brushless motor, noting that it eliminates carbon brushes to run cooler and more efficiently. This design choice in both products extends motor life and improves overall reliability. You benefit from reduced maintenance and consistent power delivery in either case. Neither tool lists a brushed motor option, so you get the same core efficiency technology in both.
Cutting Capacity
Product B offers a substantial 2-9/16 inch cutting capacity at 90 degrees, allowing it to cut through 3-inch material in a single pass. This makes it suitable for thicker lumber and structural work. Product A is a jig saw, so its cutting depth is not specified in the provided data, but jig saws generally handle thinner materials or intricate curves rather than deep cross-cuts. The Makita circular saw clearly wins for deep, straight cuts in thick wood. If you need to rip through heavy timber, Product B is the superior choice due to its large blade and depth capability.
Weight and Portability
Product A weighs 4.2 pounds, making it very lightweight and easy to handle for extended periods. Product B weighs 12.1 pounds, which is significantly heavier due to its larger motor and battery configuration. The lighter DEWALT jigsaw is easier to maneuver for detailed work and overhead cuts. The heavier Makita circular saw provides more stability during heavy cutting but may cause fatigue during prolonged use. You should consider your physical comfort and the type of cuts you perform most often when weighing this difference.
Speed and Control
Product B reaches a no-load speed of 5,100 RPM, providing fast cutting performance for circular saw operations. It also features Automatic Speed Change technology to adjust torque and speed during the cut. Product A offers variable speed control via a trigger and dial, allowing you to adjust the blade speed for different materials. While Product B has a fixed high-speed ceiling, Product A gives you manual control over the speed. For precision work on delicate materials, the adjustable dial on Product A is advantageous. For speed in softwoods, Product B is faster.

Frequently asked questions
Is 20V MAX better than 18V for table saws?
The voltage rating alone does not determine the best tool for your needs. You must look at the specific motor type and intended use. For example, a 20V MAX jigsaw offers precise control in a compact form. An 18V system can combine two batteries for higher power. Choose based on whether you need detailed cuts or heavy-duty ripping.
What is the difference between 20V and 18V X2?
A standard 20V system runs on a single battery pack. An 18V X2 system links two 18V batteries to create 36V of power. This dual-battery setup provides more torque and runtime than a single 20V pack. The DEWALT model uses one 20V MAX battery. The Makita model uses two 18V batteries for increased output.
Does a brushless motor matter in cordless saws?
Yes, brushless motors are more efficient and durable than brushed ones. They generate less heat and require less maintenance. Both the DEWALT and Makita tools in this comparison use brushless technology. This means you get longer runtime and consistent power delivery. It is a standard feature for modern professional-grade cordless power tools.
How heavy are cordless table saws compared to corded?
Cordless tools vary in weight based on their design and battery integration. The DEWALT 20V MAX jigsaw weighs 4.2 pounds without a battery. The Makita 18V X2 circular saw weighs 12.1 pounds. These weights affect portability and ease of use. Heavier tools may offer more stability but are less convenient to carry around a job site.
Can I use 20V batteries in an 18V tool?
No, battery systems are generally not cross-compatible between brands. You must use the specific battery platform for each tool. The DEWALT tool requires 20V MAX batteries. The Makita tool requires 18V LXT batteries. If you already own batteries for one brand, stick with that ecosystem to save money and reduce clutter.
What is the best saw for precise cuts?
If you need precise curve cutting, a jigsaw is the right choice. The DEWALT DC334B is designed for detailed work with adjustable orbital settings. It weighs only 4.2 pounds for easy handling. For straight cuts, a circular saw like the Makita XSR01Z is better. It delivers 36V power for clean, straight lines in thicker materials.
Do I need a special blade for these saws?
Each tool uses blades designed for its specific cutting action. The Makita circular saw accepts 7-1/4-inch blades for straight cuts. The DEWALT jigsaw uses thin, reciprocating blades for curves and intricate shapes. Always match the blade type to the tool. Using the wrong blade can damage the saw or result in unsafe cutting conditions.
