Our take on the Milwaukee 6146-30 Grinder

The Milwaukee 6146-30 is a corded 4-1/2 inch angle grinder with an 11 amp, 1,400-watt motor that spins at 11,000 RPM. Its standout feature is a paddle switch with an electronic clutch that cuts power on bind-up, plus overload protection. It is a heavy-duty tool for cutting, grinding and polishing steel and masonry, aimed at tradespeople rather than light home use. Against compact grinders it is heavier at about 8 lb and has no variable speed, but the kickback control and Milwaukee's motor reputation are what buyers pay for.

Best forMetalworkers cutting and grinding steelContractors and welders who want kickback protectionFabricators doing heavy daily grindingBuyers who prefer a paddle switch for control
Pros
  • 11 amp motor with strong torque for its class
  • Electronic clutch reduces kickback on bind-up
  • Overload protection shuts the motor down before damage
  • Paddle switch is easy to control with gloves
  • Standard 5/8"-11 spindle fits common wheels
Cons
  • No variable speed, so it is not ideal for polishing or delicate work
  • About 8 lb makes it heavy for overhead or one-handed use
  • Corded only, so it needs an outlet or extension cord
  • Paddle switch can be awkward for users used to slide switches

Questions and answers

Is the Milwaukee 6146-30 good for cutting metal?
Yes. The 11 amp motor and 11,000 RPM top speed handle cutting and grinding steel with 4-1/2 inch wheels. It is built for continuous trade use rather than occasional jobs.
Does it have variable speed?
No. The 6146-30 runs at a fixed 11,000 RPM. For polishing or work that needs slower speeds, a variable-speed grinder is the better fit.
What does the electronic clutch do?
It senses a bind-up or kickback and cuts power to the motor, which reduces the chance of the tool twisting out of your hands. Overload protection also shuts the motor down if it is pushed too hard.
What size wheels does it take?
It uses 4-1/2 inch wheels with a 5/8"-11 spindle thread, the most common size for this class of grinder.
Is it too heavy for one-handed use?
At about 8 lb it is on the heavy side for a 4-1/2 inch grinder. Most users hold it two-handed, especially for overhead or long cuts.
Where is the Milwaukee 6146-30 Grinder cheapest?
At Construction Tool Warehouse, for $139.00, as of our latest check.
Where can I buy the Milwaukee 6146-30 Grinder?
