AVID POWER MW590 Angle Grinder 4-1/2 Inch

Overview

Running on 120 volts with a 900 watt motor and a 12,000 RPM no-load speed, the AVID MW590 grinder fits the specs typical of a handheld corded grinder, at 5.1 pounds.

The listing doesn't specify disc or wheel size, so the exact application isn't confirmed by the data, but the wattage-to-RPM ratio matches the range common to corded angle grinders rather than slower bench units. Buyers should check the disc arbor size against their own accessories before ordering.

• 900 watt corded motor
• 12,000 RPM no-load speed
• 120 volt power source

Who it's for

Works for anyone needing a corded grinder for general metalworking or fabrication tasks who is comfortable confirming accessory compatibility separately. Less suited to buyers who need a specific disc size guaranteed upfront.

Pros and cons

Performance notes

A 900 watt motor at 12,000 RPM no-load speed is enough for routine grinding, deburring, or light cutting work with the right disc fitted. Being corded means constant power at the cost of a cord tether, and at just over 5 pounds it should be manageable for extended handheld use without excess fatigue.
