Does the GA4534 have a lock-on switch?

No. The paddle switch is a dead-man design with no lock-on, so the tool runs only while you hold it. It does have a lock-off to prevent accidental starts.

Can it run off a generator?

Yes. The AC/DC switch lets it run on AC or DC power, including a generator, as long as the supply meets the tool's 120V, 6 amp draw.

What discs fit this grinder?

It takes 4-1/2 inch (115 mm) wheels with a 5/8-11 UNC arbor. The spindle thread matches most standard grinding and cutoff discs.

Is it good for cutting or only grinding?

It handles both. The 11,000 RPM and 6 amp motor work well with cutoff wheels, and the guard can be adjusted for either task.

How does it compare with a variable-speed grinder?

It is simpler and lighter than variable-speed models, with one fixed 11,000 RPM. Choose variable speed only if you polish or finish with flap discs and wire wheels.
