20V vs 18V Recip Saw Specs
Voltage rating
The DEWALT DCS382B operates on a 20V MAX power source, while the Makita XRJ08Z uses an 18V LXT system. Voltage indicates the electrical potential available to drive the motor. Higher voltage often correlates with greater torque and cutting power under load. You get 20V from DEWALT and 18V from Makita. This difference may affect performance in dense materials. The 2V gap is noticeable in spec sheets, though real-world impact depends on motor efficiency. Both are cordless systems, so battery chemistry also matters. You should consider your existing battery ecosystem when weighing this spec.
Stroke length
Stroke length determines how far the blade moves per cycle, impacting cutting speed and aggression. The DEWALT model features a 1-1/8 inch stroke length. The Makita model has a 7/8 inch stroke length. A longer stroke generally removes material faster, which is useful for rough demolition or thick lumber. The DEWALT offers a longer stroke at 1.125 inches compared to Makita's 0.875 inches. This gives DEWALT an advantage in raw cutting aggression. Makita compensates with higher RPMs, but stroke length is a key mechanical difference for heavy-duty tasks.
Motor type
Both tools utilize brushless motors, a critical spec for modern cordless power tools. The DEWALT DCS382B and Makita XRJ08Z both feature brushless technology. Brushless motors eliminate carbon brushes, reducing friction and wear. This design typically extends runtime, improves efficiency, and increases overall tool lifespan. You get brushless motors in both options. There is no advantage here regarding motor technology. Both manufacturers have optimized their respective brushless systems for performance. This spec is a tie, as both tools share this core efficiency feature.
Speed control
Variable speed triggers allow you to adjust cutting speed based on the material. The DEWALT includes a 2-finger variable trigger design for ease of use. The Makita provides a variable speed range of 0 to 3,100 strokes per minute. While both offer variable control, Makita specifies the maximum RPM. DEWALT describes the trigger ergonomics but does not list a specific RPM cap in the provided data. You can adjust speed on both. Makita gives you a clear maximum speed figure. DEWALT focuses on trigger comfort. This is a slight edge for Makita due to specific performance data.
Battery included
You need to know if the tool comes with a power source. The DEWALT DCS382B is sold as a tool only, with no battery included. The Makita XRJ08Z is also a tool only, with no battery included. Both are bare tool options. You must purchase batteries and chargers separately for either saw. This is a critical spec for your total cost and setup time. Since both require separate battery purchases, neither has an advantage here. You are comparing two bare tool configurations. This aspect is a tie for both products.
Choose the Best Recip Saw For You
Heavy demolition and thick material cutting
The DEWALT DCS382B features a 1-1/8 inch stroke length. This longer stroke removes more material per cycle, making it faster for cutting thick lumber or metal. The brushless motor provides optimized efficiency for demanding jobs. You get more work done with each pass through dense materials compared to shorter stroke options.
Precision work and overhead cutting tasks
The Makita XRJ08Z is designed for one-handed operation with a compact 14.4-inch length. It weighs only 1 pound, reducing fatigue during extended use. The low vibration design offers up to 40% less shake. You can maintain better control in tight spaces or when working overhead, ensuring safer and more precise cuts.
Fast cuts with high speed settings
The Makita XRJ08Z reaches 0-3,100 strokes per minute. This high speed allows for rapid cutting in various materials. The brushless motor delivers consistent power without excess heat. You benefit from up to 55% faster cutting performance. This makes it ideal for projects where speed is critical and you need to clear debris quickly.

Frequently asked questions
Is 20V better than 18V for cutting thick metal?
Yes, the higher voltage often provides more torque for tough cuts. The DEWALT 20V model delivers strong performance for demanding tasks. You get consistent power when cutting through dense materials. The 18V option is lighter but may slow down under heavy loads. Choose 20V if you prioritize raw cutting power over weight.
Can I use an 18V battery with a 20V saw?
No, battery systems are not cross-compatible between brands. DEWALT uses its 20V MAX platform, while Makita relies on the 18V LXT system. You must stick to the voltage ecosystem of your chosen tool. If you already own batteries, pick the matching brand. Mixing systems is not possible without an adapter, which is not standard.
Which saw is better for tight spaces?
The Makita 18V model is designed for one-handed use in confined areas. It weighs just one pound and has a compact width of four inches. This makes it easier to maneuver in tight spots. The DEWALT 20V is a standard two-handed tool. You should choose the Makita if space is your primary constraint.
Do both models have brushless motors?
Yes, both the DEWALT 20V and Makita 18V saws feature brushless motors. This technology improves efficiency and extends runtime. You get longer tool life and less maintenance. Both options offer reliable cordless power. The choice depends on whether you need the extra torque of 20V or the compact size of 18V.
Is the Makita saw lightweight enough for overhead work?
Yes, the Makita 18V saw weighs only one pound. Its compact design reduces fatigue during overhead or prolonged use. You can hold it with one hand for better control. The DEWALT 20V is heavier and requires two hands. For overhead tasks, the lightweight Makita is the more practical choice.
What is the main difference between these two tools?
The primary difference is voltage and physical size. DEWALT offers 20V power for higher torque, while Makita provides 18V power in a smaller package. DEWALT is for users with existing 20V batteries. Makita suits those needing a one-handed tool. Both are bare tools without batteries included.
