Luo ke20 Pcs 𝐃𝐢𝐚𝐦𝐨𝐧𝐝 Mounted 𝐁𝐞𝐚𝐝 𝐑𝐞𝐚𝐦𝐞𝐫, 5 Different Shapes Diamond Drill Bit, 1/8 Inch Shank Diamond Grinding Tool for Dremel Rotary Tool

Good files to have on hand. They work well.

Bored a bigger hole in stubborn stone beads like butter, didn't flinch or wear down at all after many. Very pleased with this set!

Works well, worth the money, Good product.

I’m glad I got this so far it has been very helpful for my projects. It fits my rotary tool perfectly so I’m glad about that.

These attached to my dream so thats was a bonus. I didn't know they would do that. They're very durable for bead reaming. They worked out great.

Great product I needed a thin diamond shanks and these are good. Very high quality. Used these to carve through hardened steel. Never even broke or got bent. Plz keep the quality at the same level. Used with my hypertough rotary tool. Thinnest I found online. No joke they don't break even at high speeds. Highly recommended item.

I was expecting them to be cheap and of lower quality given the price and country of manufacture, but i really didn't expect them to break so quickly. I'm using them to drill holes in gemstones and minerals for jewelry. I've tried different rpm and pressure, but the tips burn out within seconds and many will just break.Overall, terrible quality and worthless

They do the job at least to increase the hole size in some softer stone, pearl -anyway it will literally sand the drill bit- and soft metals like sterling, gold and fine silver if you drill a hole and is not big enough and want just to increase it a bit. I found the conical shaped particularly useful.
