Overview
The Makita GA4030 is a corded AC angle grinder running on 110 volts, spinning at 11,000 RPM with a 720 watt motor. It weighs about 3.7 pounds, keeping it in the compact grinder class.
Compact angle grinders like the GA4030 are built for one-handed control on cutting, grinding and sanding tasks around metal and masonry. The 11,000 RPM speed and 720 watt motor put it in line with typical compact grinder specs, and the light weight matters most during overhead or extended use.

Who it's for
Metalworkers, welders and DIYers doing cutting, grinding or deburring work will find this a workable compact grinder. It is not sized for heavy-duty stock removal on large steel sections, where a larger grinder would run cooler under sustained load.
Strengths and trade-offs
Drawn from this product's published specifications.
- 3.7 pounds keeps it light for overhead work
- 11,000 RPM speed suits cutting and grinding discs
- Corded 110 volt AC power avoids battery runtime limits
- 720 watt motor is small for heavy stock removal
- Corded design limits reach compared to battery models
- No reviews on this listing to confirm long-term durability
Performance notes
The 720 watt motor driving the wheel at 11,000 RPM gives enough speed for cutting and grinding discs to work efficiently, while the 3.7 pound weight reduces arm fatigue during one-handed or overhead use compared to larger grinders.
