so far very good. put this grinder to work all day with cutting wheel to cut (32) 1"x 4" 1/8" thick steel posts. Did not miss a beat, no overheating. Excellent choice for the lightest grinder I could find at homedepot

(What's this)
Makita 10.5 Angle Grinder This Makita tool was built to take punishment grinding. The long handle and extra handle that can be placed on the right or left, adds stability while grinding. I used the grinder to cut thru old bed rails while building a special shelf design. The protective shield helps direct away the sparks and small bits of metal. Using the right cutting wheel helps get the job done right. The grinder has quiet a bit of torque so when you turn it on, hang on to it. It will get away from you if you are not hanging on. The grinder is not to heavy but it does tire you out after a long days use. That is the only drawback I could find. The off on trigger is in the long handle and makes it easy to control. I really like this piece of equipment. This Makita tool was built to the same standard all Makita tools are built to and that is a real Plus. As Always Be Safe Using This Tool

(What's this)
I opened the box, installed the Guard and Grinding Wheel and was ready to go sharpen some of my tools. Because this is the first time I have used an electric grinder, I choose to sharpen a garden shovel and pruning shears, shown in the attached photo's. The grinder has a lot of power and did the job I had hoped for. I like the option of being able to attach the Tool Handle to either side of the grinder, although I don't see me switching sides. The guard kept me safe from a possible shattering of the wheel and it also helped keep the sparks away from my body. The grinder is rated at 11,000 RPM's so you want to make sure you use a grinding wheel that is made for those RPM's. The wheel that comes with the grinder is a Type 27 36-grit INOX Depressed Center Grinding Wheel.that can be used on steel and stainless steel. The directions warn you when using a depressed center wheel to only use fiberglass-reinforced wheels. This grinder only weighs 5.9 lbs., which helps make it easy to operate and control. The instructions were easy to understand. The guard and abrasive wheel were easy to install. I am looking forward to using this grinder on other tools and projects. I do recommend the Makita 10.5 amp SJS Angle Grinder, Model # GA5020.
