Review on Efficient And Precise: Mgtgbao 8PCS Green Diamond Drill Bits Set For Granite, Marble, Tile, And Glass by Luis Shreibman

I was able to quickly make holes in granite stone and cement pavers. There was no significant wear to the drill bit afterwards. The wax of course was gone. Looks like that is a one time use feature.I suppose that one could just drill into a candle to re-apply the wax. (Sorry dear, don't know how that hole got into your favorite candle) Lastly, I would prefer if this drill bit set came in a more compact carry case. The case it ships in is almost like a display case. I am satisfied with this purchase.
