Oudtinx 50pcs Diamond Coated Grinding Head Grinding Burrs Set for Dremel Rotary Tool

Just the right set for tinkering, polishing and shaping

I bought this set because I thought they looked more durable in better attachment and consistency of the diamond. I was wrong. I love the shapes of the bits, but as I was working on this sandstone project They lost their ability to cut much quicker than the other set I have pictured

Ive been using these to clean up after I use the Dremel and so far so good. It leaves a smooth surface and different sizes has been great for those small areas that are hard to reach.

Good but very small. Works on fine areas that need sanding on hard surfaces like ceramic.

So far so good! These are awesome for carving rocks and crystals. IMPORTANT, do not push hard, use water and let the bit do the work, otherwise (past experience, not with this brand) the diamond coating will wear out faster. I definitely recommend these!

Love this product and have used it alot, forcing the bits will bend the ones that are long and pointy, but if you relax and let the bit do it’s job without adding your own force and pressure, they work nicely and stops the issue mentioned. The problem was the users fault and I would purchase this again certainly.

Quick delivery, items as described and good quality. They last quite a while, even on gun steel

I used a few of these tools so far. They seem to work great and seem very durable.

Ill admit, I trashed a couple of the burrs in this set, and it was from my mistake. For some reason, I got it in my head one day that these 120 grit burrs were 40 grit, so I started wailing on a piece of quartz with them. After I realized my mistake and started using these burrs in their proper context (which for me, is detailing stone carvings AFTER Ive roughed in desired shapes with coarser burrs), they work fine. I still think they wear a little fast, but Im a newbie to stone carving, and as its the dead of winter at the time of writing this, Im not carving stone that often since I do so in a basement thats very cold during winter. So its entirely possible that my lack of experience and lack of articulation is fully or partially to blame for the burrs wearing so fast. I was eager to try the burrs that have the larger diameter heads, but I find that theyre actually tricky to handle. Im using a rotary tool that has a flexible line attachment, and its harder to articulate the pressure I apply to my workpiece with the larger burrs. I dont have this issue with the burrs that have smaller diameter heads. But thats just my experience, your mileage may vary, both in how the burrs feel to you and how long they last. I do want to point out I dont carve stone wet; I will occasionally stop and dunk my workpiece in water, but I dont have a means to keep water constantly flowing on my workpiece and tool at this time, so that may be another factor in why the burrs have worn relatively quick for me. I dont know if Ill buy these again when I need more burrs, but Im not unhappy with them yet I dont feel that theyre outstanding in any way either.

They wear out fast but they do cut real well both metal and stones like quarts, and steel but for the price I think its a great deal
