The Makita XSH04ZB 18V LXT Lithium-Ion Sub-Compact Brushless Cordless 6-1/2 Inch Circular Saw is a blade-right cordless circular saw built for cutting and ripping tasks where size and control matter as much as raw power. This is a circular saw designed for framing, roofing, formwork, and general construction cutting. Model Number XSH04ZB. If you want 18V platform compatibility but do not want to drag around a full-size saw for every cut, this one is aimed squarely at that gap.

What makes this saw stand out is how much performance Makita packs into a smaller body. The brushless motor spins at 5,000 RPM, which gives the saw the speed needed for common lumber cuts and quick rips. Makita also adds Automatic Speed Change technology, which adjusts cutting speed and torque during the cut. In plain terms, that means the saw reacts better when the material pushes back, so it stays more consistent instead of feeling weak once the blade is buried in the work.

The compact layout is a big part of the appeal. At only 10-5/8 inches long, the Makita XSH04ZB is easier to position in tighter spots than a bulkier rear-handle or full-size sidewinder. That matters when you are trimming sheet goods on the floor, making quick cuts from staging, or reaching into awkward framing layouts. The blade-right design also gives right-handed users a familiar sight line to the cut, and the top handle keeps the grip natural for one-handed repositioning between cuts.

Capacity is still jobsite-useful. You get a 2-1/4 inch max cutting depth at 90 degrees and 1-5/8 inch max cutting depth at 45 degrees, along with a bevel range of 0 to 50 degrees. That covers common framing lumber and a wide range of angled cuts without stepping up to a larger saw. The included 6-1/2 inch 24-tooth ultra-thin kerf carbide-tipped blade is also a smart match for a cordless tool because it reduces drag and helps stretch runtime.

Makita did not leave out the details that affect everyday use. Dual LED lights help when you are cutting in dim areas or inside partially finished spaces. The electric brake stops the blade quickly, which speeds up repetitive work and makes the saw feel more controlled when you move from cut to cut. There is also a built-in dust blower to keep the cut line visible, an on-board blade wrench so adjustments do not turn into a scavenger hunt, and a flat motor housing that gives the saw more stability during blade changes.

Build materials matter here too. The aluminum base and magnesium blade cover help keep weight down while still giving the saw the durability expected on a construction site. Makita also includes Extreme Protection Technology for improved dust and water resistance in harsh conditions. Add the included dust extracting attachment and rear dust port vacuum connection, and the saw is better suited for indoor remodeling or any job where controlling debris helps keep the space workable.

On the battery side, this saw is part of the Makita 18V LXT platform, so it works with Makita 18V LXT and Compact Lithium-Ion batteries that have the Star symbol. That matters if you are already invested in Makita because this tool drops right into the system instead of forcing you into another charger and battery line. Makita also states runtime of up to 174 crosscuts per charge in 2x10 SPF lumber when used with one 5.0Ah battery, which gives a solid real-world idea of what the saw can handle on a charge.

Who should buy it? Contractors and serious DIY users who want a lighter, more compact cordless circular saw for everyday cutting, especially framers, builders, roofers, and remodelers. If your priority is the biggest blade and the deepest cut possible, look at a larger saw. If your priority is portability, control, and staying on the Makita 18V LXT system, the Makita XSH04ZB 18V LXT Lithium-Ion Sub-Compact Brushless Cordless 6-1/2 Inch Circular Saw makes a lot of sense.
