255 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 Metabo G18ST runs on a 3950-watt motor, the highest motor power figure listed in this grinder batch. Its 6000 RPM no-load speed is lower than several competitors in the same category, reflecting a torque-oriented design rather than a high-speed finish-grinding focus. At $159 it occupies a mid-to-upper price position among the angle grinders here.
Weighing 10.8 pounds, the G18ST is noticeably heavier than most competing models. The published dimensions are 12 inches by 12 inches by 12 inches. Owners rating it 4.5 stars across 255 reviews suggest solid satisfaction among those who have purchased it, though the review count is modest compared to category leaders.
With zero reported purchases last month, current market momentum for the G18ST appears limited. Buyers evaluating it should weigh whether the 3950-watt motor output justifies the heavier form factor and higher price against lighter, faster-spinning alternatives.
Pros
- 3950-watt motor rating is the highest in this batch for raw cutting and grinding power
- 4.5-star rating from 255 verified buyers reflects solid owner satisfaction
- Published dimensions provide clear bench and storage planning information
Cons
- 10.8 pounds is the heaviest build in this batch, creating more fatigue on sustained overhead or vertical use
- 6000 RPM is among the lower no-load speeds listed, limiting high-speed finishing work
- Zero units purchased last month indicates very limited current buyer demand

What buyers say

Frequently asked questions
Is the Metabo G18ST heavy to use?
Based on its listed weight of 10.8 pounds, it is heavier than most other cordless angle grinders in this category. Users doing extended overhead or vertical work may find it tiring more quickly than lighter alternatives.
Why does the Metabo G18ST have low recent purchase numbers?
The listing shows zero units bought last month. This may reflect niche appeal or a product that suits specific professional use cases rather than broad DIY demand. The 255 existing reviews still provide useful owner feedback.
