I received this grinder yesterday, so this is an early assessment. My old (cheap) grinder had given out, and I was looking for something to: use as a general purpose grinder for lawnmower blades, general metal grinding, and chisel and tool sharpening. Generally speaking, the grinding wheels that come on bench grinders aren't suited for tool sharpening, they are too coarse and the wheel tends to overheat the metal edge. I looked at specialized sharpening machines, but they are expensive and not suited for general purpose grinding, and I didn't want to buy two tools. My compromise was to buy a good quality bench grinder and get a higher quality grinding wheel for my sharpening needs. I opted for a Norton 3x blue wheel in a 100 grit. These wheels run cool and are supposed to last 3 times as long as a regular wheel. So- I had the wheel and yesterday I got the grinder. Opened the box from Amazon and there was another box inside. Opened that box and there was another box inside- suffice it to say it got here safely! Good job, Amazon. There was some assembly required; attach the spark shield, attach the particle guards, and attach the tool rests. I turned it on and was surprised at how quietly it ran, it spooled right up to speed, but it started to walk across the bench- I needed to follow the directions and fasten it down. I replaced the finer wheel with the one I bought and commenced setting up to sharpen some dull chisels. A wrench is not included. First was to fine tune the wheel to reduce the wobble- mark with pencil and place masking tape under opposite points under the flanges, it now runs pretty well but not perfectly. I then took my brand new wheel truing tool (sold separately) and took down the high spots, so the wheel runs true in circumference. Finally, time to get to the chisels. The tool rests are not particularly well designed, in fact they're kind of cheap- stamped out of a single piece of steel, one was bent and I had to use a hammer and anvil to get it in shape. The rests do not adjust for angle, they simply slide front and back. Get it close to the wheel and that's all you can do. Once the grinder was fastened down, a bulb (40 W max., not included) was put in the light, and the wheel trued up, I was able to get the sharpening done in about ten seconds per chisel. I really like this grinder, it is basically a very good tool. It has a very robust feel, a heavy gauge electrical cord, a rugged switch, generally a solid feel. I think I am going to come up with some new tool rests and throw the factory ones away, though. I like the fact that the power switch is sealed from grit and dust, and the light is on a long adjustable stalk, and is very bright and useful (it works independently of the grinder power switch). The motor is quiet, smooth and powerful. I like the fact it runs an 8" wheel because the larger size runs cooler and cuts flatter. I like that this is built ruggedly, it feels like it will last a long time. I had considered the Delta grinder with the adjustable speed feature, but I think I made the right choice with the Sunex, it seems like it is designed and built to last.One more thing- I watched a youtube video on grinders and watched how to sharpen a drill bit (hint: don't rotate the bit). I had to try it, and was pleasantly surprised at how quickly and easily it can be done. The trench in the right tool rest seems to be designed for positioning drill bits for sharpening.
