Sent the first one back as only hummed wouldn’t rotate. The second one armature must be bent as unbalanced and wobbled. This had to be one sent back as plastic bag around motor was off.

Garbage. 3/4 horsepower? Not a chance. Takes 30 seconds to get spinning, has ZERO POWER when actually trying to grind something. Totally taken for a ride on this one. Company should be ashamed that they actually market this thing

A little noisier than expected, but other than that a good buy.

 

Lets start with the BAD The grinder arrived with loose and some missing hardware in the box. The packing is not up to specs for something of this weight. The clear plastic and aluminum shields were bent and the clear plastic scratched and cracked at the screw hole. One tool rest was bent and had a manufacturing defect. The GOOD... the wheels and motor were intact and in good condition. The motor and assembly appear to be well made, it spins up, and works as advertised. Now the UGLY, the tool rests and pretty much everything attached to the motor assembly is junk. The tool rests are made from 2mm stamped sheet metal. You can flex it with a finger. One tool rest was damaged during the stamping process and required extensive straightening and shaping to make it useable. Three of the threaded holes for installing the tools rests onto the wheel shields were misaligned and had burrs. I got the grinder assembled and attempted to use it, the tool holders would flex with anything other than light pressure. I ended up cannibalizing my old Craftsman's tool rests, which are 7mm and solid metal. Pictures provided. There are also misaligned threads on the face shield mounts as well as damaged bolts and screws. I don't recommend this grinder for anyone who is not willing or capable of extensive rework. Will update as required.UPDATE: One year in and the on/off switch stopped working. I was grinding a 5/8 nut to make it thinner and the grinder just powered down and stopped. I attempted to turn the power off but the switch was frozen open. The power switch is a generic rong feng two pole switch , so I ordered a replacement on ebay. One more failure and this POS is going to find a new home.

It showed up damaged. Left side wheel broken and parts bent. After taking the bent parts off because I needed to use it right away the motor works.

I find the motor very slow to get up to speed. I have always used 6" grinders and have found them to get up to speed rather quickly.

Works well. I’m expecting a long service life believing it’s well built/balanced with great bearings given how long it takes to wind down after you turn it off.

Very weak, takes some time to get up to speed. And hardly nothing to stop it. Both wheels were out of balance. And loose

I’m giving this bench grinder four stars because it needed a little work. The grinder arrived in time as stated, even if it hadn’t this should not be a reflection on the grinder itself and how it is rated. Although the shipping box was in excellent shape, the product box was a little messed up. However, this has no bearing on the validity of the product. Too many people drop their evaluation percentage of a product because of late shipping/arrival or packaging problems. Rate the product on how it functions folks. OK, first, the grinder vibrates excessively, causing the screws holding the eye protectors together to fall out. The eye protectors come assembled, but not installed. The vibration also makes a lot of noise, which could necessitate the use of ear protection. I also had purchased a WEN 4288 Cast Iron Pedestal Stand on which I installed the grinder. After the installation in my basement, I turned on the grinder and let it run. It was LOUD. My wife, upstairs, said the nose was really loud. Second, this also involves the eye protectors, the aluminum frame holding the plastic protectors onto the grinder is lame. The frame is crimped onto a small rod that is bent and bolted to the inside wheel cover. This needs to be crimped tighter than done at the factory. During assembly they came loose, allowing the clear plastic eye protectors to free fall against the grinding wheels. I’m expecting this will be a minor problem in the future. I’ll deal with that when, and if, it occurs. Third, the grinding wheels are not balanced and they wiggle when the machine is first turned on. I’m sure this causes some of the vibration. There is almost 1/8th to 1/4th-inch wiggle in both grinding wheels. One can really see this problem after turning the grinder off and watching the wheels as they slow down and come to a stop. The machine itself does what is advertised. It is a strong enough machine to do most grinding one will need. Having once had a small engine repair shop, I would have used this grinder to do what I needed. It will definitely provide all of the grinding requirements for the handyman, homeowner or DIY person. Now, a solution to the excessive vibration and noise. While pushing, poking, pressing and stretching on the grinder and its wheel covers, I discover that a simple solution to much of the vibration and noise was to stretch the wheel covers outward. This eliminated a lot of the vibration, hence the elimination of most of the excessive noise. I then took a ¾” x ¾” x 13¾“ piece of wood and placed it snuggly between the tops of the wheel covers (I actually had to gently hammer it in place with a small ballpeen hammer. Afterwards, my wife said she could not hear it.). As for the screws coming loose, I’ll add some lock tight to them. I am now satisfied with the grinder and expect to get many years use from it. I would recommend the machine to anyone. I’ll update my review if necessary.

Got this from Amazon.com. Wow, this worked wonderfully -- right out of the box: No vibration, powerful motor (5 amps), smooth operation when using it, and it seems to have some reasonably strong components! After its first use, just to check its operation, I then replaced the wheels. My suggestion is to replace the grinding wheels, which are just average quality (most
