Overview
With 3,960 reviews at 4.8 stars and 200 units bought per month, the Makita 9557PBX1 is the standout choice on buyer confidence alone among all the grinders reviewed here. Its 900-watt motor and 11000 RPM top speed place it at the upper end of the lighter corded grinder class, with the faster RPM compared to the 9557PB variant giving it better disc surface speed for cutting and finishing work.
At $109.00 it matches the base 9557PB on price while delivering 11000 RPM versus 10000 RPM. The PBX1 designation typically indicates a kit configuration, meaning buyers may receive additional accessories in the box, though accessory contents are not detailed in the listed specs. The listing does not publish weight or dimensions, so direct portability comparisons require manufacturer documentation.
For buyers who want the strongest possible combination of price, verified owner satisfaction, and performance at the $109 level, the 9557PBX1 is the most data-supported choice in this entire corded grinder group.
