This is another great tool from Milwaukee. I’ve been wanting (needing) a good die grinder. This M12 FUEL Right Angle Die Grinder fits the bill well! It runs at 4 different speeds (10,000, 15,000, 20,000, and 24,500 RPM) which are easily set with the press of a button. These speeds allow it to be used on a variety of different materials, with commonly available burrs, points, stones, disks, etc., even buffing. And, of course, the speed can be controlled (within each set speed) with the trigger (which has a safety lockout lever as well). It comes with (2) 2.0Ah batteries, a 12V charger, collet wrenches, and a nice, fitted, zippered case. Its compact design allows it to be used in tighter spots than other grinders. The right angle design makes it usable in situations where a straight shaft tool would be more difficult or awkward to use.
I recently replaced the deadbolt locks on my daughter’s outside yard gates with double keyed locks to keep the kids in and uninvited “guests” out. The holes in the frames were too small for the new bolts, so I used this die grander to enlarge those holes, using a ½ in. burr. The burr is intended to operate at 8,000 rpm, so it was easy to set the grinder at 10,000 rpm and control the speed a bit lower with the trigger. Worked great! Had the job done in very little time with almost no effort.
This die grinder far surpasses the usability of my ¼” straight shaft corded grinder and my ¼” pneumatic grinder. The corded one runs at 34,000 rpm which is far faster than most burrs, disks, etc. are designed to operate at. The pneumatic grinder requires more air volume than my current compressor is capable of producing. And, of course, to use either one of them requires dragging a cord or hose around, which makes some tasks more challenging.
Now I just have to “want” a straight, long shaft die grinder to match.
