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

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

Well way to small for what I am doing which is tile. Will never use them

For the money they are a good buy. Not as durable as I would like but also were not expensive.

I loved the overall quality. Evenly spaced grits and a very durable shank. Ive been using the same bit for about 35 minutes of work so far!

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

The grinding bits wear down to quickly, but they do grind.

Good Starter Set. Upgrade the ones you use the most.

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.

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

Just the right set for tinkering, polishing and shaping
