Milwaukee has never been known to follow convention, and they've stuffed the 6121-30 with a bunch of invaluable features for maximum user-frendliness. This 11 Amp 4-1/2" Small Angle Grinder has a unique trigger grip that provides extended reach and better control. If you have a long day of work ahead of you, the paddle switch and its "lock on" feature will be a godsend, making extended operation much easier. Included with the tool is a 3-position handle that has a soft grip for more comfortable and controlled operation. Keeping dust and debris out of the internal components is important for a happy and healthy tool. The Debris Baffles ejects harmful particles via airflow. The guard can be adjusted without using additional tools. Changing out brushes on the 6121-30 is easy due to the external brush doors, which offers direct access. Tools Plus guarantees you won't find a better price on the web for this or any other great Milwaukee Power Tools.

Rated 5 out of 5 by from I can't live without this angle grinder! I'm a US Army veteran. I make music therapy instruments out of old propane tanks for Vets with PTSD. These instruments need to be precisely tuned and the this angle grinder allows me to do that. I use it for sanding and cutting. The power and reliability of it allows me to make the accurate cuts needed. Hundreds of veterans that have had their lives changed and many had their lives saved because of this tool. I tried many other brands before this one and none worked well enough. Thank you from this Veteran and hundreds of others. You have a customer for life

Rated 5 out of 5 by from Great Grinder! I Recommend It To Anyone: I Manily Use This Product To Grind Down Welds After I've Completed The Project. It Runs Great, Don't Stall Out, Over Heat, Or Any Of The Things A Lesser Product Does. This Is A Safe Tool To Use, And You Can Count On It To Do A Great Job, And I Do Use It For Other Things, Such As Removing Rust, Etc. And It Always Comes Through For Me. I Recommend It To Anyone Who Needs A Great Grinder Of This Size For Any Job They Might Have To Do.

Rated 5 out of 5 by from Great tool I don't know what I did before I got this- I'm using it all the time. I'm glad I got the longer handle. Adds stability and easy grip. I can still lock the trigger for the rare one handed operation. Wire brushes are hazards- get a face shield.

Rated 5 out of 5 by from Is it possible to attach a buffing pad to this tool? I'd like to double the use of this to include buffing for furniture finishing and auto polishing. Anyone have experience with this?
