Overview
The DEWALT DCG416B delivers 1550 watts of motor output at 9000 RPM on the DEWALT 20V MAX platform. The 1550-watt figure is the highest motor power rating among all 20V grinders in this batch, making it a standout for sustained heavy-duty work within the 20V cordless tier. The listed weight is 16 ounces, which is an exceptionally low figure for a cordless angle grinder.
At $139 the DCG416B positions itself as the performance leader in the 20V cordless category. It is a tool-only purchase, so DEWALT 20V MAX battery owners can put it to work immediately, while new users will need to factor in battery and charger costs. The 9000 RPM speed is consistent with the other top 20V options in this batch.
The purchase data for the DCG416B leads this entire batch: 3,000 reviews at 4.7 stars and 700 units bought last month. That level of active buyer validation is rare and signals a product that consistently meets or exceeds expectations across a wide range of users.
