Overview
The 9557PBX1 is an electric grinder from Makita, running on 120 volt corded power with a 900 watt motor rated at 11,000 RPM. Those figures point to a handheld angle grinder, though exact disc diameter was not listed.
Makita's grinder line is built around corded, high RPM motors for cutting and grinding metal, and the 900 watt, 11,000 RPM combination here sits in the range expected of a mid-size angle grinder. A 4.8 rating from nearly 4,000 reviews is a strong result for a tool in daily shop and jobsite use.

Who it's for
Fits buyers who want a corded, high RPM electric grinder for metal cutting or grinding work and are comfortable with a plug-in tool over a cordless one. Anyone needing a battery powered grinder or a specific disc diameter confirmed in writing should verify the listing directly.
Strengths and trade-offs
Drawn from this product's published specifications.
- 900 watt motor rated at 11,000 RPM
- Corded power avoids battery runtime limits
- 4.8 rating from close to 4,000 reviews
- Disc diameter not listed in the spec sheet
- Corded design limits use away from an outlet
Performance notes
At 900 watts and 11,000 RPM, the motor sits in the range built for continuous metal cutting and grinding rather than light polishing work. Corded 120 volt power removes any battery runtime limit, at the cost of needing an outlet or extension cord on site.
