Diamond Burr Bits,Carving Drill Bits,Diamond Burr Bits Drill Kit for Rotary Tool Metal Woodworking Router Grinding Engraving Carving- 1/8"(3mm) Shank (60)

Used to attach to my stemmed for earring making. Great price and many uses. Found all I needed with this set.

Great for art work and carving in wood and cutting up metal it’s just a great package deal of carving bits

It is a good deal for the price, I had some issue with the packing. it looks like it's a return package or it just is flimsy because it is cloudy and scratched. I have yet to try them, but they seem like they will do the job. I would probably assume these are more for a couple times of use on glass, but will work longer term on other surfaces. It is cheap so what do you expect?! You get 3 of each kind though and it is definitely worth it!

So, I've boughten a number of these diamond bit packs (about 7 separate orders) over the last several years. I don't know if they were all from the same company/manufacturer, but they all LOOK the same.The first 4 I bought were pretty good. Aside from 1 or 2 of the bits in each pack, they all worked great. But then, when I bought the 5th one about a year ago, of the 3 packs that came, a little more than half were deformed. So, I refrained from purchasing more until just recently.I recently reopened my glass etching business and had an order that I needed a variety of different bits for. So I ordered these for the 6th time in 5 years. When they arrived, I opened the package and examined them. 2 or 3 of them were bent but aside from that, they looked great. So I began setting up all of my equipment so I could finish my customer's order. I put the first bit into my rotary tool, turned it on, and touched it to the glass. It made a different noise than normal and when I lifted it away, there was NO mark on the glass. I increased the RPM and tried again - still no mark. So I changed the bit. Again, the same result. Then another bit - same thing.So I used my fingers to carefully examine the texture of these bits. Despite looking like they have a rough diamond coating, they are smooth as a baby's bottom.So much so that when I tried touching it to some ultra thin stencil vinyl, just to see if it would even make a mark on that (typically bits shred through that material like a lawnmower to tissue paper) - it didn't make a scratch. I even tried pushing down with a bit of force. It left a small indent from the pressure but still didn't even scratch the material.Naturally, I ordered a replacement. It arrived the day before the customer was to come pick up his mirror. It was going to be a miracle if I could finish in time. So imagine my dismay to realize that out of the 3 replacement packs in the order, not one bit had any texture. Hence the title of this review. Because they LOOK great, as far as bits go, but it's just an illusion. They don't ACTUALLY work. They just look like they do. Don't waste your money!(And in case anyone was wondering, I couldn't finish my customer's order in time and, not only did I have to refund his $450 but he also left a very negative review for my business... AND I'm out the $120 for the mirror! All in all, these things probably cost my business more than $1,000. AVOID AT ALL COST!!!)

These Wear out so quick it’s kind of great to be able to find them for a decent price for more than just one set!

Got these for my metal artist son. Good value and quality

The price is so great and they work so well that i don't worry that I'm using it like it should be and i need to replace one. I find that I'm working more efficiently.
