A cordless saw listed as a bare tool, so battery and charger are a separate purchase. The listing is thin and its size figures are unusable, so verify details before ordering.

Overview
A brushless motor drives a rectangular high speed steel blade in this battery saw, which runs from a single pack of the same voltage platform. The grip is listed in thermoplastic elastomer or rubber, and the blade is cut for metal surfaces according to the surface field.
The reason to look at it is the brushless motor on a small battery platform, useful for people who already own packs and chargers. The limitation is the listing itself: the included field says bare tool, the unit count reads oddly, and the dimensions cannot be real.
Who it's for
Maintenance workers and tradespeople already carrying this maker's twelve volt packs can add the saw body without buying a second charger. A newcomer to the system faces a separate battery and charger purchase, and should look at a full kit instead.
Pros and cons
- Brushless motor listed
- Single battery platform to manage
- Elastomer or rubber grip material
- High speed steel blade material
- Battery and charger not included
- Dimensions in the listing are unusable
- Cutting depth and stroke not given
- Unit count conflicts with item count
Performance notes
Run time and cutting speed depend on the battery fitted, because the tool ships without one. A brushless motor reduces brush wear and wasted heat compared with a brushed design on the same pack, but the listing gives no speed or stroke figures. Blade material and tooth count govern which surface it cuts cleanly.
