Very good product

These work well. I had never drilled glass before and wanted to drill some bottles to make decorative lights. The importance of cooling is to be emphasised. I broke the first bottle, just dribbling a little water on, but succeeded on several more by drilling under running water. If you want a large hole, start small and then enlarge, using very, very, gentle pressure.

Provate per effettuare dei fori su delle bottiglie di birra, funzionano molto bene e per il momento non sembrano usurarsi troppo.
