Quick Answer
The Makita 18V LXT system offers several cordless circular saw options. The most prominent are the standard brushless 6-1/2" model (XSH03) and a sub-compact 6-1/2" variant (XSH04ZB). The XSH03 is noted for excellent cutting power and ergonomics, while the sub-compact is lighter and more portable. For metal cutting, an 18V LXT 5-3/8" saw with an electric brake is the best-rated product in its category.
Main Explanation
Choosing a Makita 18V LXT circular saw depends on cutting capacity, weight, and blade size.
1. Standard Brushless 6-1/2" Saw (XSH03)
This saw (model XSH03Z when sold as tool only) combines a brushless motor with magnesium components to reduce weight and features electronic speed control. According to a professional review, it offers excellent cutting power and some of the best ergonomics in its class. It easily cross-cuts 2x material at 90 degrees and, at a 45-degree bevel, still cuts through typical framing lumber.
2. Sub-Compact 6-1/2" Saw (XSH04ZB)
The sub-compact variant (XSH04ZB) measures 10-5/8" in length and weighs 6.4 lbs. with the battery, delivering up to 5,000 RPM. This model suits overhead work or tight spaces where weight and size matter.
3. Metal-Cutting Saw
Makita also offers an 18V LXT 5-3/8" metal-cutting saw with an electric brake and a chip collector. It is listed as the best-rated product in Makita's circular saw category on Home Depot.
Practical Takeaways
- Choose the XSH03 for a balance of power and ergonomics in general framing and sheet goods. Its brushless motor and magnesium build provide a favorable power-to-weight ratio.
- Choose the XSH04ZB if portability and compactness are top priorities, especially for light-duty cuts or working in tight spaces.
- Choose the metal-cutting saw for frequent cuts through steel or other metals.
- All claims are synthesized from product specifications and third-party reviews.
