Our take on the Milwaukee 4-1/2 in. 13 Amp Corded Angle Grinder 6146-30

The Milwaukee 6146-30 is a corded 4-1/2 in. angle grinder built around a 13-amp motor that spins at 11,000 RPM. Its standout feature is an electronic clutch that cuts power when the wheel binds, plus overload protection and a paddle switch. It is a heavy tool at about 8 lb, so it suits shop and jobsite work more than overhead or one-handed use. Against lighter 4-1/2 in. grinders it trades weight for torque and kickback safety.

Questions and answers

Is the 6146-30 good for cutting steel?
Yes. The 13-amp motor and 11,000 RPM speed handle cutting and grinding steel with 4-1/2 in. wheels. Use the correct wheel type for cutting rather than grinding.
Does it have kickback protection?
Yes. An electronic clutch cuts power when the wheel binds, and overload protection shuts the motor down under heavy load.
Is it variable speed?
No. It is a single-speed grinder that runs at 11,000 RPM, so control comes from technique and wheel choice.
What wheels does it take?
It uses 4-1/2 in. wheels with a 5/8"-11 spindle thread, the common size for this class.
Is it too heavy for one-handed use?
At about 8 lb it is on the heavy side for a 4-1/2 in. grinder. It is better suited to two-handed work at a bench or on the ground.
Does it come with a wheel?
It ships as a bare tool with a grinding wheel; check the box contents for the side handle and wrench before you rely on them.
