I purchased the Craftsman 1/6 hp 6" Bench Grinder as a replacement for an old grinder. I read several negative reviews about vibration, noise and poor running. To start with, I unpacked the unit and removed the side guards. With a permanent marker, I drew a line from the arbor out to the edge of both grinding wheels to mark the alignment. Removing the left wheel, I took care not to rotate the arbor and then performed a ring test on the grinding wheel (you can Google this to see how to do this). This MUST be done anytime a new wheel is installed. I reinstalled the left wheel taking care to align the marks, then removed the right wheel and repeated the test. I then assembled the tools rests and the spark arrestors and set the gap between them and the grinding wheels to .016" with a feeler gauge. I finished installing the face shields and gave the unit a spin by hand to assure everything cleared the grinding wheels. Finally, I moved the unit outside to a clear area and ran the unit under power for 10 minutes (turn it on from behind and get away). This proved that the unit was safe to operate. Both the running test and the ring tests are OSHA mandates for using these units in a machine shop and not a bad idea to follow at home. In conclusion, my Craftsman 1/6 hp 6" Bench Grinder has no vibration, is very quiet and performs exactly as it should. If you have vibration problems, you probably have an out of round grinding wheel. This can be set straight by shimming (Google to see how) if the wheel is out of balance laterally. If the wheel is out of round, it will need to be dressed (again, Google this and buy the correct tool to do this).
it is ok for home hobby use but under powered for any bigger work also when I put it together the mounts for the dust shields had to be modified to fit correctly
Purchased this recently at sale price -- On 2/25/2020 my order arrived: Craftsman 6” bench grinder, item# 9-211240. It is missing both tool rests, the left side tool rest bracket, and hardware for attaching the bracket and tool rests. The safety guards were bent and scraped from contact with the abrasive wheels; the left wheel housing was bent and creased; there was no wrench or product manual, and the product was scratched and dust covered, with price/inventory stickers pulled off and colored clearance/markdown stickers left behind. I had been contacted by the shipping Sears store and asked if I would accept a display item that did not have the original box, as the product is no longer in stock, to which I agreed -- if it was a new item with all the components and the product manual. I was assured it did, that it was only missing the original box. The product shipped was not complete nor in new condition. It arrived loose in an oversize box with a couple inches of packing peanuts in the bottom and a couple flat sections of air pillow, certainly insufficient to protect a 20+ lbs. metal bench machine in shipping. The missing pieces are significant parts required to use this machine for tool sharpening and for safe operation. The customer service number provided for the shipping store (XXX-XXX-XXX) in Texas comes back as “out of service.” There appears to be no available replacement inventory now available through Sears.com, either through a store or by shipment, although the item continues to be advertised in daily email messages at the sale price. Replacements for the broken parts are not available through Searsparts.com or eraplacement parts.com. If they were available, they would be more expensive than the price of the item. After contacting customer service (overseas) , I was offered a 15.00 refund which I accepted as I am a metal worker who can fabricate the replacement parts. A replacement item is not available for this previously standard item through Sears as it is reportedly a "discontinued" item and the effort to properly repackage and box this item for return shipment and time spent to do so for a full refund is more than simply inconvenient. I understand that Sears is downsizing and closing stores, but this quality of service certainly makes it hard for me to see that Sears is looking to do anything to retain its customer base, for what was once a quality brand.
