Proxxon 28326 Tungsten Carbide Micro Drills, 2-Piece

Mir war das klar, anderen ist es das wohl nicht. Also beim Bohren nicht herumbiegen sondern den Bohrer piel gerade herein und herausführen, weil er sonst beim Bohren abbrechen könnte.Bei 1,5 mm VHM eigentlich ganz normal aber wir sind ja hier nicht im Expertenforum.

Prodotto di qualità.

I kind of knew that before I bought them, but I thought I'd give it a try anyway. I bought these for my wife so she could add glass and stone pieces to her necklace making hobby (we tried diamond tipped but it was a no-go). We mounted these in our jewel makers drill press, used the recommended cutting fluid, and with very light pressure but the drill tips still snapped. These are better suited for metals like platinum, gold, silver, etc...
