327 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 SKIL 3821-01 runs a 1800-watt motor at 120 volts, pushing a 12-inch high speed steel blade at 4500 RPM. That blade speed is higher than many competitors at this price point, and the 1800-watt output matches the power class of saws priced well above $328.99.
The saw weighs 42.5 pounds, which is substantial but within range for a fixed-bench miter saw in this blade size class. With 327 reviews averaging 4.5 stars, the owner feedback base provides meaningful confidence for a sub-$350 tool.
Buyers should note that no bought-last-month data is available, so current demand trends are not confirmed. The high speed steel blade is durable and replacement-friendly, but premium carbide blades from third parties are a straightforward upgrade.
