Dremel 84922 Grinding Stone with Silicon Carbide Review

These are replacement grinding points. I've used them for a variety of tasks over the past few years and they work well. I recommend them.

Not for heavy duty/high stock removal, but great for parts and hard to reach areas. I mainly use it for "polishing/smoothing" polymer clay and UV resin crafts.

Do not buy this product. Not only are the grinding heads tiny, they don't grind either. Surface diamond dust deposited in five seconds. I'm not sure what kind of work they could be used for because I can't think of any. I'm going to Harbor Freight. Coffee at Starbucks.

It was disappointing to say the least.

This is a very nice product, well balanced and transparent. Unfortunately, even at 15,000 rpm it grinds next to nothing. The stone is extremely smooth and has no appreciable graininess; For example, at 15,000 rpm, I could only slowly grind the tip of my thumbnail off, and only after pressing down hard on it. My advice, look elsewhere; It's more like a polish than a whetstone. Go for a diamond-coated bit: it will never disappoint you! Given the price I paid for these beats I don't think I have…

Dremel tools and accessories are always miles ahead of alternatives at a bargain price. They consistently work faster and more accurately. I have yet to receive a bent replacement for a Dremel brand bit. I have never had a catastrophic failure of a Dremel grinder when used within specified parameters. Or outside of the parameters, for that matter. They almost always last longer and remain usable to the top. For work that involves moving a lot of material I take rough shots with cheap Chinese…
