20Pcs Diamond Grinding Bit Set Stone Carving Set Diamond Burr Bits Compatible with Dremel Rotary Tool Accessories YURINWOO 3mm Shank Drill Bits Set for Grinding,Stone Glass Ceramics Carving,Polishing

Needed to drill some holes in glass jars to fit LED lights for resin displays.This drill set works perfect with my Dremmel tool and drill bit selection is good. Just drilled through a tough glass jar no problem,be patient while drilling and these bits will give you perfect circles..:). Oh and it was very good value for money...

Been using them a lot, they do wear down fast but no faster than the official pieces imo and works really well considering to get the same set with dremel it would cost your soul so for the price they are great.

Used small grinder to clear grouting from a broken tile prior to lifting it. The first bit wore out after about three quarters of job done, but eventually got thee.

Very happy with the product

Well made, no obvious wear doing the job I bought them for.

They are nice but can only do so much If you want to engrave stone make unsure it’s soft They do engrave quartzite but the diamond abrasive gets worn off very quickly

It's perfect for me 100%

happy with buy.

Ottimo prodotto, materiale buono , vanno bene per l'utilizzo che me servono. Grazie

Used this set to drill into a ceramic mug and turn it into a pot plant. The bits handled the job well precise and sharp. A handy little kit for creative projects!

J’ai utiliser l’outil rond pour graver une date sur une pierre tombale et cela fonctionne très bien. La pierre est de la pierre bleu. J’ai utilisé une Dremelle avec l’outil.

Estas son las fresas que uso más.

Muy resistentes
