Milwaukee 4-1/2″ Small Angle Grinder 6121-30

Milwaukee 4-1/2″ Small Angle Grinder 6121-30 Review

There’s not a lot to say about the Milwaukee 4-1/2″ Small Angle Grinder 6121-30.  This Milwaukee grinding tool is great.  At 5.4 pounds, this too was just the right weight and size to hold and maneuver.

I used it to smooth a very rough and extremely uneven concrete wall so that I could mount a wall hung laundry sink FLAT on the wall and found the trigger easy to engage and disengage. I also used it to remove rust from a metal and it worked well asn was comfortable to use.

The 6121-30 has a trigger lock so you don’t have to hold down the trigger for it to run for long periods of time. One press of the button and it disengages it and shuts off the tool. It took more than few times for me to get used to it but with a little practice it’s easy.

The 6121-30has Overload Protection to maximize motor life, an Electronic Clutch that extends tool life and helps prevent bind-up, Line Lock-Out that prevents automatic start-up after power loss, and a Soft Start.

One of the best features is the tool free design, that allows you the hub bed wheel without a wrench.


I really liked this grinder.  You can find it for $ 109.00 online here: Milwaukee-6121-30-2-Inch-Grinder-Trigge
