What to know before buying

Listing details to confirm

The listing is inconsistent about the tool type: the title calls it a cut-off tool and small circular saw, while its description calls it a reciprocating saw. It also lists a ceramic blade and 3-inch blade length alongside circular-saw-style details, so verify the intended tool and compatible blade before buying. The displayed 500 Milliwatts wattage is also inconsistent with the stated battery-tool configuration and should not be treated as confirmed power output.

Customer feedback describes the saw as useful and convenient, with reports of good performance, ease of use and battery life. This is encouraging for buyers considering routine cordless work, but it does not resolve the listing's conflicting tool and blade descriptions. The supplied rating distribution is largely positive, with a smaller spread of lower ratings, and does not explain individual experiences.

Frequently asked questions

Does the CMCM300B include a battery and charger?

No battery or charger is listed. It is identified as a bare tool, so plan to use a compatible battery and charger you already own or source separately.

What speed and cut depth does the listing specify?

It lists a variable-speed trigger with 0–20,000 no-load RPM and a 3/4-inch depth of cut. These are listing claims, not independently verified measurements.

What should I confirm before buying?

The listing uses conflicting descriptions for the tool type and blade. Confirm the intended tool, blade compatibility and included contents for the selected listing.
