Overview
Spinning at 12,000 RPM, the GALAX 66235A-115 runs on a 520 watt corded motor and 120 volt power. Those figures line up with a handheld angle grinder.
12,000 RPM is a typical top speed for angle grinders used for cutting, grinding and surface prep. The 520 watt motor sits at the lighter end for grinders, suited to smaller discs and lighter-duty jobs rather than heavy metal fabrication.

Who it's for
DIYers and light-duty tradespeople who need a corded grinder for cutting, grinding or surface prep tasks. Heavier fabrication work may call for a higher wattage grinder.
Pros and cons
- 12,000 RPM suits standard cutting and grinding discs
- Corded design gives steady power without battery limits
- 520 watts is modest compared to heavier-duty grinders
- Disc size not listed
Performance notes
At 12,000 RPM the disc speed matches standard angle grinder use for cutting and surface grinding. The 520 watt motor draws steady corded power, though it sits below the wattage of heavier fabrication grinders, so disc size and material thickness should be matched to the job.
