Hello. i have to grind 1/16" off of the end of a kitchen backsplash. is this the best stone? what grit should i use? finished surface will not show.

It will work, though I think a flat grinding disc will work better with less chance of chipping.

Does this work with a Bosch hand grinder?

On our grinding stone the Thread is 3/8-11， if shaft of grinder adapt with this thread， then it works.

SIGNI Editorial Review

The SIGNI 4-Inch Green SiC Grinding Stone with 58-11 Thread 36 Grit is a versatile tool that can be used on various surfaces such as granite countertops, porcelain pedestals, and even quartz tabletop sink cutouts. However, customers have encountered some issues with the product. One customer reported that the wheel was egg-shaped and vibrated a lot, causing a huge safety hazard. Another customer stated that the weight of the tool was too heavy for their variable grinder, causing it to oscillate. On the other hand, a customer used it on their own granite countertops and was successful in smoothing out rough spots and even polishing them nicely. It seems that the product works fine for some but not for others.

Pros

Versatile tool that can be used on different surfaces
Can smooth out rough spots and polish surfaces nicely

Cons

Wheel may be egg-shaped and vibrate a lot, causing safety concerns
Weight of the tool may be too heavy for some variable grinders
Description of product may be hard to understand for some customers
