WARM TIP
1. When installing the grinding head, please make sure the chuck can hold 3mm shank. Meanwhile, you can use a special wrench to tighten properly and check whether it is firm and strong.
2. Wear protective equipment correctly during operation.Idling for 1-2 minutes after installation to make sure everything is normal.
3. During the grinding, the operator should stand on top of the workpiece to prevent it from flying, chipping and hurt.
4. Use the grinding head, the force should be increase slowly. If the force is too strong, the grinding head will get stuck and broken,even the machine motor will burn out. The grinding should maintain about 30° and move the grinding bits back and forth at a uniform speed.

Nice little set that I use for my dremmel. They are not the greatest quality, but you get A TON of them, so your milage is pretty good. They grid alright but can get gummed up by softer metals. I didn't notice any differences in grit, but the variety of shapes can be useful. Overall they are somewhat disposable for the price and I would buy them again.

This a nice collection of rotary grinding stones, despite the unfortunate choice of brand name. They're not the most durable, but they do work pretty well and there are a lot of them in the package. Overall a pretty good value.

These bits are very brittle. I had many that broke apart as I was using them. Mostly I used them to grind away rust from my metal gates. Fortunately you get a lot of them but the quality is not there.

I just wanted a Dremel bit to grind some blades (lawn mower, shears, loppers), but they ranged from about $15 to nearly $40 apiece. Then I found these...YES, there really are 72 grinding bits for a Dremel (or equivalent). I used ONE, and sharpened every blade in my garage. I have no idea why the others are so expensive and these are so inexpensive, but clearly, I love them!

These are very hard and do an excellent job on forged metals. I used them for grinding down/cleaning up the edges of the tabs on some brakepads and it worked great! Other color grinding tips I've used (kind of a blue green color) wore down too quickly. Not these! These help up and got the job done! Seem like quality from what I can tell so far after using only one of them quite heavily, hasn't seemed to wear at all yet!

I purchased these to make a sandstone grave marker to put over the place where I buried my dog. I don't think these were intended to be used for this purpose, however, as you can see in the pics, I was able to cut fairly deep into the sandstone. I feel they worked rather well and was quite pleased. A handful of the tips did break but considering the task at hand, I expected there would be more break than what actually did. Various sizes in a single bag. (In the pic, the bits on top are new and bits on bottom are after being used). Very durable, great price & shipped fast!
