The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Context, not marks against it, and our read of the data, not a lab test.
Overview
The CRAFTSMAN CMCS300B delivers 3000 RPM cutting speed in a package that weighs just 4.4 pounds, which is notably lighter than the kit-version CMCS300M1 at 7.06 pounds. The $79 bare-tool price makes it one of the most affordable entry points into 20V cordless reciprocating saws, and the 1,510 verified reviews at 4.7 stars confirm consistent owner satisfaction across a large sample.
The 6-inch blade capacity suits the most common cutting tasks including wood, PVC pipe, and light metal. Owners who already hold CRAFTSMAN 20V batteries can run this tool immediately without additional investment. The high-speed steel blade material supports standard cutting applications found on a typical job site or home renovation.
The 400 units bought last month place this among the most actively purchased saws in its category, reflecting genuine ongoing demand rather than a stale listing. The tradeoff versus the full kit is straightforward: no battery or charger is included, so first-time buyers into the platform need to budget accordingly.
Pros
- 4.4-pound weight makes it among the lightest 20V reciprocating saws in this price range

- $79 bare-tool price is highly competitive for the 20V cordless segment

Performance notes
Battery-powered, 20V platform, bare tool only. Speed is 3000 RPM. At 4.4 pounds this is a lightweight build that reduces arm fatigue on extended overhead or one-handed cuts. Blade material is high-speed steel. Maximum blade capacity is 6 inches. No published stroke length spec in the listing.
What buyers say
Owners consistently highlight the low weight and solid build for the price. The most common positive note is how well it fits into an existing CRAFTSMAN battery collection. Criticisms tend to focus on the bare-tool-only format and the modest blade capacity compared to larger full-size reciprocating saws.
