207 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 Worx WX812L.9 operates on the Worx 20V PowerShare battery platform and reaches 8500 RPM at no load. Its compact form factor is reflected in the published dimensions of 5 inches by 5 inches by 13 inches. The tool weighs 2.59 kilograms. At $119 it sits in the mid-tier of the 20V cordless grinders in this batch.
Motor power is not published in the available listing data. The 8500 RPM speed is capable for standard angle grinding applications including disc grinding, surface prep, and wire brushing. The Worx PowerShare platform spans a wide range of 20V tools, meaning existing Worx users can draw on batteries they already own.
With 207 reviews at 4.6 stars and zero reported purchases last month, the WX812L.9 has positive owner feedback but limited current commercial traction. Buyers inside the Worx ecosystem will find it a practical addition; buyers choosing a cordless platform fresh may find more compelling review volume elsewhere at this price point.
