realmente buenas brocas, perfore piedra de artesania y son excelentes

I had a dream and a Dremel that I wanted to use to drill holes in stones for jewelry. Initially the internet suggested that I:1) get the adapter to turn my dremel into a drill press (great advice), and2) use diamond-coated grinding bits to do this (terrible)I ended up with a broken stone after 15 minutes of trying to gently work through the stone (it also barely made a dent before the stone broke), SO, I flipped back through the different options, and then I bought theseLIKE A HOT KNIFE THROUGH BUTTER in comparison. Drilled 5 stones so far, each one took less than a minute and turned out perfectly.They come with the correct-sized cup to hold the various-sized bits in your Dremel. No issues, a million stars.

I bought these for drilling sea glass and pottery. They are really good and I’ve found them to last a lot longer than I expected for the money. Very happy and will buy again once these have worn down 👍🏼

Unter Wasser gerade zu bohren ist nicht ganz einfach aber auch harte Steine lassen sich gut und sauber bearbeitenBin sehr zufrieden damit, hatte anfangs Bedenken! Ergebnis ist einwandfrei.

I like that the bits are well made and durable
