434 owner reviews, fewer than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other power tools and workshop machinery we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The DEWALT DCS512B runs on a 12V battery and lists an 8-inch cutting capacity with a weight of 2.8 kilograms. At $163.89, it is priced similarly to the 20V tool-only options in this batch while operating from the lower-voltage 12V platform. No RPM or motor wattage is listed in the available data.
With 434 reviews at 4.5 stars and zero units sold last month in this dataset, the DCS512B is a lower-velocity listing. The review base reflects moderate satisfaction but at a pace well below the top-demand 20V saws. Buyers should confirm that their DEWALT 12V battery packs are compatible with this model before purchasing.
The combination of 12V power and 8-inch listed capacity is an atypical pairing in this dataset, where most full-blade-diameter saws run on 60V or higher-voltage platforms. Buyers comparing it to the 20V and 60V options here should note that voltage directly affects available torque, so the DCS512B is best evaluated within the 12V compact segment.
Pros
- 4.5 stars from 434 verified buyers
- Lightweight at 2.8 kilograms for a saw with an 8-inch listed capacity
- Fits the DEWALT 12V compact battery platform for buyers already in that ecosystem
- $163.89 pricing is in line with 20V tool-only alternatives
Cons
- 12V limits available torque and sustained cutting power compared to 20V and 60V alternatives
- No RPM or motor wattage listed, making performance comparisons difficult
- Zero units bought last month indicates low current demand

Performance notes
The DCS512B operates on a 12V DEWALT battery and weighs 2.8 kilograms. The listed cutting capacity is 8 inches. No speed (RPM) or wattage figures are published in this listing. High speed steel is listed as the blade material. Buyers should account for the power constraints of a 12V platform relative to the higher-voltage cordless saws also available in this category.
What buyers say
Owners who rate the DCS512B positively cite its compact weight and suitability for work where a lighter 12V tool makes sense. At 434 reviews, the sample is moderate. Some buyers note limitations in sustained cutting power compared to higher-voltage alternatives, consistent with the 12V form factor.
