Overview
A corded electric angle grinder from AVID, model AG684, running on 120 volt AC power with a 750 watt motor and a no-load speed of 11500 RPM. At 3.2 pounds it is light for a grinder in this power class.
An 11500 RPM top speed paired with 750 watts is typical of small angle grinders built for cutting, grinding, and surface work on metal, and the light 3.2 pound body should help with control during handheld use. Disc size is not listed, so confirm compatible wheel diameter before buying replacement discs.
- 120 volts AC corded
- 750 watt motor
- 11500 RPM
- 3.2 pounds
Who it's for
Fits users doing metalworking, fabrication, or general grinding and cutting tasks who want a corded tool with steady power rather than battery runtime limits. Less suited to users who need cordless portability away from an outlet.
Strengths and trade-offs
Drawn from this product's published specifications.
- Light 3.2 pound body for one-handed control
- 750 watt motor with 11500 RPM speed
- Corded power avoids battery runtime limits
- No listed disc or wheel diameter
- Corded design limits use to where an outlet is available
Performance notes
The 750 watt motor and 11500 RPM speed give this grinder enough power for typical cutting, grinding, and surface prep tasks on metal, while the corded design means output does not taper off the way a battery tool's can as it drains. At 3.2 pounds it should be easier to control one-handed than heavier grinders in the same power range.
